Description

In the present invention, in a database for browsing and evaluating patent publications of domestic and foreign third parties collected under the relevance to a specific technical theme, information on the results of evaluating individual patent publications can be collected by multiple people. It relates to a "patent information display program and display method" for obtaining good visibility when viewing and sharing information on a .

In product design in the engineering department of the manufacturing industry and research and development in research laboratories, new development projects are investigated in order to investigate domestic and foreign patent publications of other companies that are highly related to newly developed products and elemental technologies. Periodic surveys are conducted using retrospective surveys (also called theme surveys or technology trend surveys), SDI (Selective Dissemination of Information) searches, and the like.

Devices such as patent management databases for recording the results of the investigation and sharing information are often devised as in-house systems operated within manufacturing companies. The device ranks and records the patent publications collected in association with the technical theme and the results of evaluating the patent publications by engineers and researchers who are directly involved in the technical theme as importance information. A technology has been proposed that enables searching for patent publications and importance information to be shared among users.

With the recent progress in the digitization of patent publications, patent search systems based on electronic data have become widespread, making it easy to obtain a large number of domestic and foreign patent publications, and recently, an AI-based search function has been added. While the system is becoming more sophisticated year by year, the system's user, the manufacturing industry, has a database that stores the many patent publications collected for research and the results of evaluating these patent publications. It remains a simple function that only displays a list, and there is a problem in terms of ease of browsing and information sharing. In addition, as the number of recordings on the database increases due to regular surveys such as SDI, management becomes more difficult.

In the first place, the amount of information contained in one patent publication is enormous, and the individual results of evaluating a large number of patent publications depend on who is in charge of the evaluation. It is important not only to share one-sided information such as whether or not the results of evaluation have been recorded, but also to record and share information such as evaluation of importance and countermeasures based on the results. It is necessary to reduce the burden on evaluators who browse patent publications and their evaluation results by displaying records of the relevant information with good visibility even if the number of patent publications increases.

The present invention has been made in view of such circumstances, and is a method that provides excellent visibility of patent information that is collected and accumulated in one's own department and that is closely related to the product and development technology that one's own department is responsible for. To provide a patent information evaluation system which can be appropriately managed by a person in charge, can efficiently share information between groups inside and outside an organization to which a person in charge belongs, and has an excellent user interface.

One aspect of the patent information display program in the present invention is a patent information display program that has a storage unit and a calculation unit that store a patent evaluation database, and that is executed in the calculation unit, wherein the user uses the patent search system. Patent information including at least bibliographic items such as the application number of the published patent publication obtained by A set of one or more patent evaluation records with the same application number in the theme table, in which patent evaluation records linked with information are associated with a theme table set for each theme and accumulated in the patent evaluation database. , a group formation process in which the patent evaluation record with the smallest record number is the representative of the set, and a list of the patent evaluation records accumulated in association with the theme table specified by the user are provided to the user. a display process to be presented on the terminal, and in the group formation process, the representative application number of the group of patent evaluation records managed in the theme table, or the application number or publication number in the patent family , if the application number or publication number of a patent evaluation record with a large record number matches, the patent evaluation record with a large record number is incorporated into the group as a patent evaluation record belonging to the group, and in the display process, the patent Regarding the group of evaluation records, the representative of the group, the state in which the patent evaluation records belonging to the group are expanded and displayed directly under the representative, and the patents other than the representative belonging to the group by displaying only the representative The patent information display program presents the patent evaluation records of the group so that the user can recognize them as a group of patents by switching between a collapsed state in which the evaluation records are not displayed and a state in which the evaluation records are not displayed.

One aspect of the patent information display method in the present invention includes patent information including at least bibliographic items such as application numbers of published patent publications obtained by a user using a patent search system, and Display of patent information displayed on a display device in association with a theme table set for each theme, a patent evaluation record in which attached evaluation information is associated with incidental information including a record number assigned to each case in descending order. A method, wherein, in a set of one or more patent evaluation records having the same application number in the theme table, group formation processing in which the patent evaluation record with the smallest record number is used as a representative of the set; a display process for presenting a list of the patent evaluation records accumulated in association with the theme table specified by the user on the terminal of the user, and in the group formation process, If either the representative application number of the group of patent evaluation records or the application number or publication number in the patent family matches the application number or publication number of the patent evaluation record with a higher record number, the higher record number A patent evaluation record belonging to the group is incorporated into the group as a patent evaluation record belonging to the group. By switching between an expanded list display state and a collapsed state where only the representative of the group is displayed and the patent evaluation records other than the representative belonging to the group are not displayed, the patent evaluation records of the group can be displayed. This is a display method for presenting patent information so that the user can recognize it as a group of patents.

When displaying a list of the huge number of patent publications in Japan and overseas recorded in the patent information evaluation system, they are automatically correlated based on the application number and patent family to obtain good visibility. The practice of evaluating and monitoring third-party patents within the department will be streamlined.

Embodiment 1
BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, embodiments of the present invention will be described with reference to the drawings. First, the patent information display program and display method in the embodiments described below are collected for the purpose by displaying groups of domestic and foreign patent families in association with the basic application number of the application claiming priority. Improve the visibility of the entire list of patent publications. In particular, in the patent information evaluation system that implements the present invention, new patent publications of patent families whose foreign applications have been filed in multiple countries are automatically placed in the patent family group at the same time as they are imported into the system. By doing so, it becomes easier to compare and refer to new patent publications of the relevant patent family with reference to patent information that has already been evaluated. In addition, patent families often have almost the same content, with only differences in the content of claims depending on the country. can greatly reduce the burden of

A patent information evaluation system that implements the present invention in the embodiment can be realized by executing a patent information display program on a computer having a storage unit (not shown) configured with a database and a computing unit that executes the program. Below, a patent information evaluation system will be described as an example of a method of implementation. It should be noted that the patent information evaluation system is composed of a server that executes a patent information display program and a client terminal that refers to patent information.

<System configuration>
FIG. 1A is a configuration diagram of a patent information evaluation system 1 of this embodiment. The patent information evaluation system 1 is a WEB system composed of a commercial database 2, a server 3, and a plurality of client terminals 5 via an in-house intranet line 4. FIG. The commercial database 2 is an example of a patent search system in which patent information is accumulated, and a public patent search system available free of charge can also be used.

The commercial database 2 is a search and browsing system for domestic and foreign patent publications operated by a private intellectual property-related information service business company, and is installed in the company's internal network that uses it, or the information service business As an Internet connection service with a contract ID issued by a company, employees of the company use it as a practical user.

In this embodiment, domestic and foreign patent publications (patent publication publications, patent registration publications, etc.) recorded in the commercial database are downloaded in text files such as csv (Comma Separated Value) format, and managed by the above users. A user having administrative authority imports it into the designated theme table 31 of the patent evaluation database 30 of the server 3 and accumulates it as a patent evaluation record 700 .

The employee user can access the server 3 using the WEB browser of the client terminal 5 and refer to or edit the patent evaluation records stored in the theme table of the patent evaluation database 30 according to the usage authority.

In the patent information evaluation system according to the present embodiment, the server 3 has a patent evaluation database 30 , a database management section 33 and a display processing section 34 . The patent evaluation database 30 includes patent information 710 that includes at least bibliographic items such as application numbers of published patent publications obtained by the user using the commercial database 2 (or patent search system), A theme table in which a patent evaluation record 700 is generated by linking the attached evaluation information 720 and incidental information 730 including a record number assigned to each case in descending order by a positive integer starting from 1, and set for each theme. 31 and accumulated in the patent evaluation database.

In the theme table 31 of the patent evaluation database 30, the database management unit 33 designates the patent evaluation record with the smallest record number in a set of one or more patent evaluation records with the same application number as the representative of the set. group formation processing is performed. In addition, in the group formation process, the database management unit 33 selects the representative application number of the group of patent evaluation records managed in the same theme table as the designated theme table, or the application number or publication number in the patent family. and the application number or publication number of a patent evaluation record with a higher record number, the patent evaluation record with the higher record number is included in the group as a patent evaluation record belonging to the group.

The display processing unit 34 refers to the patent evaluation records, and presents on the terminal of the user a list of patent evaluation records that have been accumulated in association with the theme table specified by the user.
Here, with respect to the group of patent evaluation records, the display processing unit 34 displays the representative of the group, the state in which the patent evaluation records belonging to the group are expanded and displayed in a list directly under the representative, and only the representative. The patent evaluation records of the group are presented so as to be recognized by the user as a group of patents by switching between display and a folded state in which the patent evaluation records other than the representative belonging to the group are not displayed.

Details of the configuration of each part in the server 3 as the core function of the patent information evaluation system 1 will be described below.

<server>
As shown in FIG. 1A, the server 3 includes a patent evaluation database 30, a database management section 33, a display processing section 34, and an update processing section . Also, the server 3 is configured by a processor (CPU), a hard disk, a memory, and a server operating system (not shown), and maintains high network performance and stability.

The patent evaluation database 30 includes N theme tables 31 (N is a natural number), and a user definition table 32 that associates and stores user authority (create, reference, edit, delete) for each theme table.

One theme table 31 corresponds to one technical theme. M (M is a natural number) patent evaluation records 700 are stored. One patent evaluation record 700 includes patent information 710 , evaluation information 720 , and additional information 730 . (Fig. 1B)

As shown in FIG. 1C, the patent information 710 includes elements such as "status" 711 and "application number" 712, which are bibliographic items consisting of texts downloaded from the patent publications in the commercial database 2, abstracts, claims, and the like. included. In addition, the evaluation information 720 includes elements such as “importance” 721 that records the result of the user's evaluation of the patent publication, comments, and the like. Further, the incidental information 730 includes elements such as a "record number" 731 assigned to each case in descending order by positive integers starting from 1, and a "record pointer" 732 for forming a record group. . The record pointer stores a physical address as a reference destination of a patent evaluation record other than its own belonging to the same record group.

As shown in FIG. 1E, in the process of forming the record group, in a set of one or more patent evaluation records 700 having the same application number in the theme table, the patent evaluation record 700 having the smallest record number as a representative of the set, NULL is written in advance to the record pointer as the terminal value, and when a new patent evaluation record with a record number greater than the patent evaluation record is added to the group, the terminal value NULL) is rewritten to a physical address indicating the reference destination of the new patent evaluation record, and a termination value (NULL) is written to the record pointer of the new patent evaluation record. Each time a new patent evaluation record is added to the group, the terminal value (NULL) is rewritten to form a record group.

By the process of forming the record group, in the display process, the patent evaluation records of the group are regarded as a group of patents by continuously performing the reference process via the record pointer in the record group. can be displayed.

The database management unit 33 has a core function of the patent evaluation database 30, and can access a designated theme table to obtain any patent evaluation record. In addition, a function to import domestic and foreign patent publications downloaded from the above-mentioned commercial database into the database in csv file format, a user management function for registering and authenticating users of this system, contents of the patent evaluation database It has a function to output to a file.

The display processing unit 34 includes a list display unit 34p that outputs a list of the patent evaluation records 700 that exist in the theme table 31 corresponding to the technical theme when the user logs in and selects the technical theme that the user is in charge of, A detailed display means 34q for displaying the patent evaluation records 700 so that they can be referred to or edited according to the user authority recorded in the user-defined table 32; A cross-tabulation means 34r is provided for setting and graphing the results of cross-tabulation of a plurality of items of each analysis axis.

The update processing unit 35 sets the element "importance" 721 of the evaluation information 720 of the patent evaluation record 700 to "high" among "high", "medium", "low", "noise", and "not set". request the latest application/right status of the patent evaluation record 700 corresponding to .

Since the application/right status information of the patent publication in the commercial database is updated according to the prosecution progress, when the update processing unit acquires the latest application/right status information of the application number from the commercial database 2, If there is a change, the “status” 711 and “right state” 716 included in the patent information 710 of the patent evaluation record 700 with the “importance” 721=“high” are updated. As an example, "status" 711 = updated from "published" or "examination request" to "registered", or "right status" 716 = from "rights continued" to "rights revoked".

However, in order to acquire information through the above API linkage, it is assumed that the information service company that operates the commercial database prepares the above API linkage service for the purpose of improving the value of the service and expanding the market. be. In addition, the API linkage service will be made available only to companies with which the information service company of the commercial database has signed an introduction contract for the system, and will be operated after ensuring a sufficient level of security by the information service company. should be done.

<Client terminal>
The client terminal 5 is a so-called personal computer equipped with basic software (operating system), control/arithmetic unit (CPU), storage device (memory, hard disk), input/output device (keyboard, mouse, display), etc. (not shown). It is configured. The client terminal 5 may be a user's personal smart phone or tablet terminal.

<Logging in to the system and displaying a list of patent evaluation records>
Hereinafter, an operation example of the patent information evaluation system 1 (especially the server 3) is based on the processing of the flowcharts (FIGS. 2A, 2B, 3A, 3B, 3C, 4A, 4B, and 5) and the processing concerned. List display screen (FIGS. 6A, 6B, 6C, 6D), detail display screen (FIGS. 7A, 7B), patent map display screen (FIGS. 8A, 8B, 9A, 9B), login screen (FIG. 11) will be explained.

When the patent information evaluation system 1 is started, the login screen 120 shown in FIG. logs into the server 3 (S000), the list display screen 60 is displayed in the list display format 1 (S101) as shown in FIG. 6A. In the upper part of the list display screen 60, tab icons 60a showing the names of "technical themes" corresponding to all the theme tables 31 in the patent evaluation database 30 are displayed side by side.

Immediately after login, the leftmost tab is selected by default, and all patent evaluation records corresponding to the "technical theme" are displayed in a list with the list tab 62a selected. On the list display screen 60, when the user clicks and selects one of the tab icons of technical themes related to the team to which he/she belongs or the product he/she is in charge of, the theme table 31 corresponding to the selected technical theme All patent evaluation records 700 are immediately listed and output to the client terminal. (S101)

<List display screen>
The list display means 34p displays each element included in the patent information 710 and the evaluation information 720 that constitute one patent evaluation record 700 for each row and each column to display a list of all patent evaluation records. , to the client terminal 5 .

FIG. 6A shows a display output example of all patent evaluation records 700 included in the theme table 31 corresponding to the technical theme “system” as an example of the list display screen 60 . The list display screen 60 includes a "check" column 65a for selecting a patent evaluation record 700, an "F" column 65b indicating the existence of a patent family, and an "importance" recording the user's evaluation result of the patent evaluation record. Based on the contents of 721, the "importance" is converted into a character string such as "high" = ◎, "medium" = 〇, "low" = △, "noise" = x. 65c.

In addition, the values of each column such as "Judgement", "Applicant", "Status", "Application Number", "Publication Number", "Patent Number", and "Invention Title" are displayed. It should be noted that other items after "Title of the Invention" can be displayed by sliding the horizontal scroll bar.

The list display screen 60 has a tab 61a that displays patent evaluation records of Japanese patent publications and a tab 61b that displays patent evaluation records of foreign patent publications. The patent evaluation records are switched and displayed.

Furthermore, the list display means 34p can control switching between folded display and expanded display, which will be described later, and display a list in descending order of importance and output it to the client terminal 5. FIG.

<Detailed display screen>
When one of the patent evaluation records 700 displayed as a list is selected (by checking the column 65a with "check mark") and the display button 64a is pressed down, or a mouse operation such as double-clicking is performed (S102 ), a detailed display screen 70a (FIG. 7A), which is the first detailed display format, is generated as a separate screen and output to the client terminal 5 by the detailed display means 34q. (S103)

Since the user normally selects one technical theme for which he/she has the editing authority to view and edit the patent evaluation record, the detailed display screen has a display format that allows both viewing and editing. be.

As shown in FIG. 7A, the detailed display screen 70a displays the contents of the patent information 710 and the evaluation information 720 of the patent evaluation record 700. FIG. An area 72 is an area for displaying constituent elements of the evaluation information 720, and includes a theme name, an "importance" field, and user's "judgment" (for example, "caution", "hold", "reference", etc.), Each field of entry person, entry date, etc. is included.

The "Importance" field is an input field for recording the "Importance" 721 of the evaluation information 720 in which the unique judgments of the user and the product/technical department are recorded. One of "medium", "low", "noise", and "blank (unfilled)" is set. The area 71 contains the components of the patent information 710: “status” 711, “application number” 712, “publication number” 713, “patent number” 714, “filing date” 715, “right status” 716, “patent Family” 717, etc. are displayed.

The patent family indicated by "patent family" 717 is based on the idea that a plurality of patent applications with completely the same priority information are regarded as a "patent family" by the information service company that operates the commercial database 2, and the priority information is Although there are differences in thinking, such as defining even one patent application as a “patent family,” the corresponding patent family is composed of the corresponding foreign application (including PCT application) publication number or application number claiming priority. Information. The patent family may also include divisional applications.

The “comment” 722 of the evaluation information 720 is the content describing the “importance” 721 which is the result of evaluation by the user and the process and grounds of the “judgment”, and is displayed in the “comment” tab 722 to be used by the user. to help other members of your team understand. Information such as "summary", "claims", and "FI/CPC", which constitute the patent information 710, are separately described in adjacent tabs, and the contents of the tabs can be switched and displayed by operating the mouse. .

In addition, an operation button for editing the evaluation information 720 and an operation button for ending editing and closing the screen can be arranged on the detailed display screen 70a.

<Management screen>
When the "management" tab 69 of the list display screen 60 shown in FIG. 6A is selected, the screen is switched to the management screen 100 shown in FIG. 10 (S001). Domestic and foreign patent publications downloaded from the commercial database 2 are imported into the patent evaluation database 30 by operating the management screen. In addition, a process of setting user authority in association with user registration and technical themes (S002), a process of outputting to a file all patent evaluation records in the theme table corresponding to each technical theme or all technical themes (S003), It is possible to perform database management operations such as

<Importing patent publications>
In the patent information evaluation system according to the embodiment, the incidental information of the patent evaluation record has a "record pointer" 732 indicating the reference destination of the patent evaluation record other than itself in the group constituting the patent family, and database management is performed. The unit 33 assigns a preset termination value (for example, NULL) to the record pointer, and the application number or publication number of the newly added patent evaluation record is the representative patent evaluation record of the group constituting the patent family. or the application number or publication number in the patent family, the physical address indicating the reference destination of the newly added patent evaluation record is rewritten. Further, the display processing unit 34 displays a series of patent evaluation records followed by reference processing via a record pointer as a group of patents. Therefore, the patent publication import process for creating a new patent evaluation record will be described below.
When actually importing patent publications into the patent information database, as shown in FIG. By selecting the type of search (regular search or theme search) and the country of search (Japan or foreign country), specifying the file of the patent publication list in csv format downloaded from the commercial database 2 and importing it, the patent publication can be registered as a patent. The process of reading into the theme table 31 of the evaluation database is started.

In the import process, as shown in the flowchart (S500) of FIG. It is copied (S501) and added to the theme table 31.

At the same time, the priority claiming application number or publication number included in the "application number" 712 or "patent family" 717 of all existing patent evaluation records 700 in the subject table and the newly added patent publication number A process is performed in which the application number or publication number is compared and collated.

In this process, the “application number” 712 of the patent information 710 of all the patent evaluation records (m: m=1 to M) in the existing 1st to Mth theme tables and the new patent evaluation record (M+1 ) is compared with the application number of (S502, S503). If the application number is the same, the "record pointer" 732 of the supplementary information 730 of the patent evaluation record (m) is referred to (S504), and it is compared whether it is NULL or not (S505). , and refers to the patent evaluation record indicated by the physical address (S506).
S505: S504 to S506 are repeated until YES, and when "record pointer" 732=NULL is detected, it is determined that the end of the existing patent family is formed.

Next, by substituting the physical address of the new patent evaluation record (M+1) into the record pointer 732 of the existing patent evaluation record (m) (S507), the patent evaluation record (M+1) constitutes a new patent family. be recognized as a thing. At the same time, NULL indicating the end of the patent family is written to the "record pointer" 732 of the new patent evaluation record (M+1) (S508).

On the other hand, if the result of the comparison processing in S502 and S503 is negative, the presence or absence of the application number or publication number of the new patent evaluation record (M+1) in the "patent family" 717 of the patent evaluation record (m). It is retrieved (S509).

As a result of the search, if it is determined that the relevant application number or publication number is included (S510: YES), it is determined that it is a patent evaluation record of a group that constitutes a patent family, and the process returns to S504 and performs the same procedure as above. It is processed and becomes a member of the patent family group. If not included, NULL is written (S508), and the next patent publication recorded in the csv file is read.

The series of processes described above is a method of constructing a data structure that connects records in a daisy-chain fashion, generally called a linear list. If the value is not NULL, it indicates the physical address of the patent evaluation record (m) to be referenced next, and if NULL, it is recognized as the end indicating the last patent evaluation record (m) added to the group.

In this way, as shown in FIG. 1E, it is possible to link and record patent evaluation records that constitute a series of patent families associated with application numbers or application numbers claiming priority.

<Reading patent evaluation records and folding display>
The patent evaluation record 700 is stored in the theme table 31 in a state of being associated with the “record pointer” 732 by the patent publication import process shown in S500 described above. Therefore, when displaying the entire patent evaluation record of the theme table as shown in FIG. 6A, it is possible to read out and display on the client terminal 5 in units of groups that constitute the patent family.

In the above display, as shown in the theme table reading process (S200), all the patent evaluation records 700 are sequentially read from the top of the specified theme table 31 (S201), and the incidental information 730 of the patent evaluation record " A record pointer' 732 is referenced (S202), and whether or not it is NULL is evaluated (S203). If it is not NULL, the patent evaluation record is referenced by the physical address indicated by the record pointer (S204). Processing moves to the patent evaluation record, and all the patent evaluation records 700 of the theme table 31 are read.

Furthermore, in order to enhance the eye-catching effect of showing the existence of the patent family in the list display, the list display means 34p indicates that the group of patent evaluation records constituting the patent family is the representative patent evaluation record of the group. A marker "+" 67a is displayed in the "F" column 65b to indicate that the representative indicating the existence of the group and the patent valuation records other than the representatives that make up the patent family are included in the group. . (Fig. 6B)

With the above display method, it is possible to clearly show that the representative of the group of patent evaluation records other than the representative is folded under the representative, and when the marker "+" is clicked, the patent family are expanded, and all the patent evaluation records are continuously displayed directly under the representative. At the same time, the marker "-" 67b indicating that all the patent evaluation records of the group constituting the patent family are in an expanded state is displayed, and the F column 65b of the remaining patent evaluation records expanded and displayed immediately below A marker “├” 67c and a marker “└” 67d indicating the end of the last patent evaluation record are displayed.

As described above, the existence of the patent evaluation records of the groups constituting the patent family is indicated by the marker "+" 67a, and only the patent evaluation records of the representative of the group are displayed, so that the existence of the patent family can be easily grasped. In addition, the display space can be saved, so that the visibility of the entire theme table composed of patent families in the technology theme and other patent evaluation records is improved.

In this system, regardless of the existence of a patent family, Japanese and foreign patent valuation records are imported and added to the patent valuation database using different csv files each time a periodic search is conducted. Furthermore, since foreign patent publications are published at different times in each country, they are not necessarily included in the same csv file, and there is a high possibility that the patent families will be dispersed chronologically.

In addition, it is not yet decided when the foreign patent gazette will be available for download from the commercial database 2. However, as described above, the user can check whether the patent family is included in the csv file downloaded from the commercial database, regardless of the publication date, using the patent evaluation record of the application number claiming priority as a representative. Without worrying about it, as soon as the relevant patent family is included at the same time as the import, it is possible to link the patent evaluation records of the groups that make up the patent family automatically.

If the newly added patent evaluation record is a record group of any patent family by the above processing, by expanding and displaying the record group, the "importance" 721 etc. of each patent evaluation record is displayed. Since the entry status can be known, when the user evaluates the new patent evaluation record, in the patent evaluation record having the patent information 710 that has the same contents of the claims, the filled-in "importance" can be used as a reference. If so, the load of evaluation work for the new patent evaluation record can be significantly reduced.

The patent evaluation records 700 of Japanese patents and foreign patents are recorded in the same theme table 31, and on the list display screen 60, tabs 61a and 61b are provided so that Japanese patents and foreign patents can be browsed separately. However, the user is freed from the trouble of switching the list display by switching tabs between the "Japan" tab 61a and the "Foreign country" tab 61b, searching for the patent family by application number, etc., and performing an evaluation. It is possible to save unnecessary man-hours for treating the existence of already evaluated patent families as first-time users without being aware of them.

<Representative of the group that constitutes the patent family>
As described above, as an example of the display method on the Japan tab 61a of the list display screen 60, a patent family group is composed of patent publications having the same application number of the relevant patent publications and patent publications of divisional applications (published publications). patent publications, registration publications), as well as foreign patent publications with application numbers claiming priority from Japan. Among them, the representative of the group is the patent evaluation record that is always displayed even if the display of convolution and expansion is switched at 67a and 67b.

The "record number" 731 of the incidental information 730 of the patent evaluation record is incremented by 1 each time it is recorded in the theme table 31 as described above, and each time a patent publication is read into the theme table from the csv file, the record is changed according to the flowchart of S200. Since the process is executed in descending order of the number, the patent evaluation record with the smallest record number in the patent family is representative. Therefore, in the patent gazette with the same application number, the patent evaluation record whose "status" 711 is "published" chronologically earlier than "examination request" or "registered" can be the representative of the group of the patent family, and the application As soon as the patent evaluation records of the second country and beyond are included in the theme table, they will form the relevant group.

On the other hand, the display method in the foreign country tab 61b should originally be the patent evaluation record with the same application number as the application number claiming priority, but Depending on the chronological order of reading the csv file, the patent evaluation record may become the representative of the group that constitutes the patent family because the record number is smaller.

<Read out and list in order of importance>
In the patent display system according to the embodiment, when displaying a list of a plurality of patent evaluation records accumulated in the patent evaluation database 30, the display processing unit 34 sorts them in descending order of importance based on the judgment of the user. Displayed in the order of 1. Further, when the first order is the same order, the display processing unit 34 performs at least one of the following orders (1) and (2):
(1) The order of the application/right status is after registration and still in existence, request for examination, publication, reasons for refusal, decision of refusal, after registration and cancellation of rights.
(2) In descending order of the application/right status, which has been registered, has been registered, and has been in existence for a long period of time.
is the second order, and a list of a plurality of patent evaluation records is displayed in descending order within the second order.
The contents of the element "importance" 721 of the evaluation information 720 of the patent evaluation record 700 include "high", "medium", and "low" as a result of evaluating the individual patent evaluation record by the user in charge of the technical theme. , “noise”, and “blank (not evaluated)” are recorded. Further, the user evaluates the patent evaluation record 700 in which "status" 711 = "registered" and "right status" 716 = "right surviving", and sets the "importance" 721 to "high". , the "application number" 712 and "application date" 715 of the relevant patent evaluation record 700 and the physical address (not shown) are added to the most important table 31A shown in FIG. 741, "filing date" 742, and "record pointer" 743, sorted and recorded in ascending order of filing date.

In the reading process of all patent evaluation records 700, as shown in flowchart S220, the list display means 34p sets the "importance" 721 in the order of "high", "medium", "low", and "noise". They are read out in descending order from the “importance”=“high” and displayed on the list display screen 60 as a list. First, "application date" 742 from the most important table 31A in which the information of the patent evaluation record of "importance" = "high" and "status" 711 = "registration" and "right status" 716 = "right surviving" is recorded. The patent evaluation records are read out in ascending order of rights, that is, in ascending order of rights duration (S240).

In the patent evaluation record reading process of flowchart S240, the physical address of the patent evaluation record (not shown) recorded in the "record pointer" 743 of the most important table 31A is referenced to read the patent evaluation record (S241).

Next, the "record pointer" 732 of the incidental information 730 of the patent evaluation record is referred to (S242), and it is compared whether it is NULL or not (S243). A physical address is indicated, and the patent evaluation record is read by the physical address (S244). When NULL is detected, it is determined that reading has been completed up to the end of the group of the patent family, and the next most important table 31A is read. By repeating S242 to S244 until NULL is detected in this manner, the patent evaluation records described in the most important table can be read out including a series of patent families, as shown in the schematic diagram of FIG. 1F.

Next, for all patent evaluation records with "importance" 721 = "high" (S221), the combination of "status 711 and state of rights 712" is "request for examination: -", "disclosure: -", and "reasons for refusal: -", "decision of refusal" or "registration: cancellation of right" is read out in descending order. That is, the "status" 711 is read for "examination request" (S222, S200), then the "status" is read for "publication" (S223, S200), and then the "status" is read for "rejection" (S223, S200). reason" (S224, S200), then all the remaining patent evaluation records are read (S225, S200).

Next, the patent evaluation records 700 whose importance is "medium" are read (S226, S200), then those whose importance is "low" are read (S227, S200), and finally those whose importance is "noise" are read. It is designed to be read out (S228, S200). In addition, patent evaluation records with "importance" = "high" and "status" 711 = "registered" and "right status" 716 = "right surviving" may be displayed in different colors according to the number of remaining years. , for example, red indicates 10 years or more remaining years, orange indicates 5 to 9 years, and yellow indicates 2 to 4 years. Alternatively, the remaining years may be color-coded by shades of the same color (eg, red).

<Updating the most important table (1)>
As shown in the flowchart of FIG. 4A, the user evaluates the patent evaluation record from the detailed display format 1 screen (S103), sets the "importance" 721 to "high", finishes editing, and saves the record (S401). It is evaluated whether or not the “status” 711 of the evaluation record is “registered” (S402), and further whether or not the “right status” 716 is “right surviving” (S403). If both are YES, the "application number" 712 and "application date" 715 of the relevant patent evaluation record are copied to the "application number" 741 and "application date" 742 of the most important table 31A, respectively, and the patent evaluation The physical address of the record is copied to the "record pointer" 743, and further sorted and recorded in ascending order of the "filing date" 742 (S404).

<Updating the most important table (2)>
The update processing unit in the embodiment periodically refers to and acquires the application/right status information included in the patent information 710 of the patent evaluation record 700 from the commercial database 2 based on the "application number" 712, and updates the application. - Update the application/right status information included in the patent information of the patent evaluation record if the right status information has been changed. Processing for updating the application/right status information will be specifically described below.

The application/right status of the patent publications recorded in the commercial database 2 is updated at any time.
Therefore, when the csv file is imported into the patent evaluation database 30, the "status" 711 and the "right status" 716 of the patent evaluation record 700 in the theme table will be the corresponding patent application/right in the commercial database. A problem arises in that the states deviate with the lapse of time.

In order to solve this problem, the update processing unit 35 has a function of periodically accessing the commercial database 2 using the API protocol about once a week. "Status" 711 and "State of Rights" 716 of the patent information 710 of the patent evaluation record are obtained by obtaining the latest progress information from the commercial database using the "application number" 712 as a key. Update content.

As for the above process, as shown in the flow chart S410, after performing the authentication process (S411) with the commercial database, for the patent evaluation record with the "importance" 721 of "high", the "application number" 712 is (S412), and transmits an API protocol for inquiring the latest status and rights status corresponding to the "application number" to the commercial database (S413).

Then, upon receiving a response from the commercial database (S414), the "Status" 711 and "State of Rights" 716 of the patent valuation record are compared with the received status and state of rights (S415), e.g. 711 is "publication" or "examination request" and the received status is "registration" (S416), the "application number" 712 and "application date" 715 of the patent evaluation record, and the The physical addresses of the patent evaluation records are newly added to the most important table 31A as application number 741, filing date 742, and record pointer 743, respectively, and at the same time, arranged in the most important table 31A in descending order of long term. Therefore, the "application date" 742 of the most important table is compared and sorted in ascending order (S417).

On the other hand, as a result of S415, if the received rights status 716 is "revoked" (S418), the most important table corresponding to the "application number" 712 of the patent evaluation record One item of information recorded in 31A is deleted, and the filing dates of the most important table are compared and sorted in ascending order (S419). Since this result is automatically reflected in the list display of the list display screen 60 and the detail display screen 70a, the latest status and right status of the patent evaluation record whose "importance" 721 element is "high" can be edited. You can check the application and rights status of the latest patent evaluation record at any time, regardless of whether the user who was in charge of this or the member who is in charge of the same technical theme in the department to which the user belongs can view it at any time.

In addition, regardless of the degree of importance, the patent evaluation record is edited every time the user receives progress information from the commercial database, such as the user's effort to set progress monitoring by application number etc. on the commercial database 2. Since it is possible to save time and effort to manually reflect the results, the efficiency of the patent monitoring work on the patent evaluation database can be greatly improved. In the commercial database 2, a patent number is assigned when the application/right status is newly registered. A new number will be recorded in "Patent number". Similarly, information on the patent family is updated as needed, such as when a new foreign application is published, so the "patent family" 717 may also be included in the update target.

<Search mode: Search by control number>
The display processing unit 34 in the embodiment uses the "application number" 712, the "publication number" 713, and the "patent number" 714 of the patent information 710 as management numbers, and assigns users in a plurality of theme tables with editing or management authority. In a certain theme table, when one of the numbers included in the management number is specified as a search key and a search is performed, the patent evaluation record having the same management number as the search key is extracted and displayed. . In addition, list the patent evaluation records having the application number or publication number that matches the application number or publication number recorded in the "application number" 712 or "patent family" 717 of the patent evaluation record as a group. . On the other hand, if there is no patent evaluation record with the same management number as the search key in the theme table for which the user has editing or management authority, the search range is expanded to all theme tables and the same management number as the search key is found. to extract and display only the patent evaluation records that have The process of displaying the patent evaluation record to be searched by the two display methods in the display processing unit 34 will be specifically described below.

For technical themes that the user is in charge of and has editing authority for, clicking the search tab 62b on the list display screen 60 (FIG. 6A) enables switching to the search mode (S104). In the search mode, as shown in FIG. 2B, flow chart S300, when the application number (or publication number or patent number) is entered in the input window 62b1 and the search button 62b2 is pressed, patents including the application number in the patent information 710 are searched. Search the rating record 700 .

First, the presence or absence of the relevant patent evaluation record is confirmed from the theme table 31 corresponding to the relevant technical theme (S301). are output in list display format 1 (S302, S303, S304, S305). When a patent evaluation record to be viewed is selected from the display of the list display screen 60 and the display button 64a is pressed (S102), the detailed display screen 70a, which is the first detailed display format editable by the user, is displayed as a separate screen. It is generated and displayed on the client terminal 5 . (S103)

On the other hand, if it does not exist in the relevant theme table, it is checked whether it exists in another theme table (S306). Name" and only the relevant patent evaluation record is output in list display format 2. (S307, S105) As shown in FIG. 6D, the list display format is a display format in which the "technical theme name" 62b5 in which the patent evaluation record is recorded is specified in the "importance" column 65c.

When a patent evaluation record to be browsed is selected from list display format 2 and the display button 64a is pressed (S106), a detailed display screen 70b, which is the second detailed display format shown in FIG. Output to 5. (S107) On the detailed display screen 70b, the area 72 corresponding to the evaluation information 720 and the comment 722 are grayed out so as to indicate that the evaluation information cannot be changed because the user does not have editing authority, and the detailed display screen 70b is displayed. The display format is such that it can be seen at a glance that it is different from the screen 70a.

The display format clearly indicates that the patent evaluation record belongs to a theme outside the editing authority of the user, and on the other hand, although the theme is different from the theme in charge of the user, other users can enter the degree of importance. If there is a record in the or comment column, the record can be referred to, which may lead to unexpected information discovery between users who share the same upper organization.

Furthermore, if it does not exist in any of the theme tables 31 of the patent evaluation database 30, based on the application number entered in the search input window 62b1, a URL protocol that conforms to the regulations shown in the service manual of the commercial database 2, etc. is generated by the detailed display means 34q and transmitted to the commercial database (S308). indicate. (S309)

In this way, even if there is a patent evaluation record corresponding to an application number that does not exist in the patent evaluation database 30, it is possible to access a huge number of domestic and foreign patent publications recorded in the commercial database 2, and the application number ( Or you don't have to set up and rerun commercial databases to look up patent publications by publication number or patent number.

<Patent map display>
The display processing unit 34 in the embodiment visualizes the number of subsets forming the patent evaluation record group at each intersection point on the analysis target axis specified by the user with respect to the plurality of patent evaluation records selected by the user. If the user is presented with a patent map that displays the analysis results shown in Add a highlighting effect to the analysis results. The processing of this display processing unit 34 will be specifically described below.

Select a plurality of patent evaluation records displayed as a list on the list display screen 60 (Fig. 6A) in the "Check" column 65a, or press the select all button 64b for selecting all patent evaluation records, and press the MAP button 64c. is pressed, a map setting screen 110 as shown in FIG. 8A is displayed (S108).

Here, the patent map refers to information such as applicants, inventors, application numbers, etc., and patent classification information such as FI and F terms, which belong to each patent information in a population of multiple patent information. Therefore, the number of cases matching these is statistically aggregated, and the number of cases is shown graphically or graphically. On the map setting screen, the map type is selected in map selection 111, and the X axis and Y axis are input in setting items 112 and 113 from pull-down menus (not shown).

The setting item "X axis" 112 can be selected from a pull-down menu such as first FI, F term, IPC, application number, middle classification, etc., and the setting item "Y axis" 113 can be selected from the same pull-down menu as applicant, inventor , etc., and when each selection is made and the OK button 114 is pressed, a patent map screen 80 as shown in FIG. 8B is displayed by the cross tabulation means 34r (S109).

In the example of the patent map shown in FIG. 8B, the leading FI extracted from the element "FI" of the patent information 710 is set on the X axis, and the element "applicant" of the patent information 710 is set on the Y axis. , a visualization element 81 representing the number of patent evaluation records corresponding to a specific applicant by the size of a circle is allocated and arranged at each position corresponding to the XY two-dimensional coordinates. .

Here, the cross-tabulation means 34r sets the coordinates corresponding to the X-axis: "first FI" and the Y-axis: "applicant" of the object including the patent evaluation record 700 with "importance" 721 = "high". In the area indicated by a certain visualization element 81, a point-like marker 82 indicating the presence of "high" importance is displayed. Punctate markers are, for example, dots or figures that create a large color contrast with their surroundings. In addition, if the outline of the area of the corresponding visualization element 81 is thickened or the entire area is emphasized with a different color contrast, not only the patent evaluation record 700 whose importance is "high" but also the corresponding Attention to other patent valuation records included in the area indicated by the visualization element is also highlighted. Also, it becomes easier to compare the area with other areas in the entire patent map screen 80 .

For example, if the technical theme includes an application filed by the company and is set in the population of patent evaluation records for displaying the patent map, the importance indicated by the marker 82 is "high". Since the comparison between the visualization element 81 indicating the area where the patent evaluation record 700 exists and another visualization element 81 indicating the application area of the company is made clearer, it can help the company's patent application strategy.

In addition, a character string 83 such as "publication number" 713, "patent number" 714, etc. is displayed by a lead line from the location of the dot-like marker, or the character string is popped up by placing the pointer display of the mouse. By associating the dot-shaped marker 82 with the character string 83, it is possible to more specifically indicate the information of importance=“high” indicated by the marker.

Further, when the latest progress information is acquired from the commercial database 2 by the update processing unit 35, and the "status" 711 of the patent evaluation record 700 with the importance of "high" is changed from "examination request" to "registered." Furthermore, in correspondence with the marker 82 indicating that the "importance" 721 = "high" patent information, the character string 83 also changes from the "publication number" 713 to the "patent number" 714. can also be reflected

Further, by clicking the corresponding circle of the visualization element 81 of the map, only the patent evaluation records 700 belonging to the corresponding area may be listed on the list display screen 60 . Also, in the patent map type selection, when the "shading chart" is selected from the map selection 111 of the map setting screen 110 and displayed, the visualization element 81 is indicated by a rectangle centered at the intersection of the X coordinate and the Y coordinate, The number of cases occupying the rectangle is indicated by shades of the same color such as grayscale.

<Map animation>
The display processing unit 34 in the embodiment displays the variable analysis target axis based on another analysis point on the patent map displayed in the above-described predetermined format, and displays it in accordance with the change of the value of the variable analysis target axis by the user. to change the analysis results on the patent map in conjunction with it. An example using the filing year as the variable analysis target axis will be described below.

As shown in FIG. 9A, in addition to the X-axis and Y-axis, a switch 91 is turned on to set the "year of application" as an additional axis to be analyzed, and a slider 92 is displayed. By changing the range of the "application year" with the slider, the patent map is dynamically changed like an animation so that the size of the visualization element 81 by the patent evaluation records 700 included in the range is changed accordingly. By changing the display (S110), a more visually impressive effect can be achieved.

The cross tabulation means 34r turns on/off the display of all the visualization elements 81 and the visualization elements 81 and markers 82 that include projects of high importance as if interlocking with the operation of the slider 92, and turns on/off the display of the visualization elements 81. You can change the highlighting of the outlines of the areas shown.

Specifically, for example, as shown in FIG. 9A, when the application years are set to 1999 to 2006, the marker 82 is not displayed in the upper rightmost visualization element 81 on the patent map. When the application year is set to 1999 to 2015, a marker 82 is displayed on the uppermost visualization element 81 on the map.

This means that the applicant/first FI corresponding to the uppermost visualization element 81 on the two-dimensional map applied for the application year between 2007 and 2016, and "importance" = "high" indicates that there is a patent valuation record that has been

In this way, by dynamically changing the map display M according to the filing year, etc., the degree of growth of the map can be drawn in animation, and the development in the technical area indicated by the visualization element 81 containing the projects with high importance is possible. Trends and other companies' market entry status can be communicated more impressively to team members and management other than users.

<Modification: Configuration>
One of the plurality of client terminals 5 may be a terminal of an external patent research company. For example, for a patent research company that is granted network access rights based on a relationship of trust with a company that requests patent searches (theme searches, regular searches), a searcher belonging to the patent search company By directly importing the patent gazettes downloaded from the above commercial database 2 into the user's patent evaluation database 30, for example, conventional csv files or Excel files are attached to e-mails and the results of investigations are sent to the requesting company. If the patent has been delivered, there is no need for clerical work associated with the delivery, and the burden on the patent evaluation database manager can be greatly reduced.

Moreover, the patent evaluation database 30 constituting the present embodiment may be a function extended to the commercial database 2 . For example, by providing a list display screen 60 or the like by the list display means 34p as an optional function of the commercial database, engineers and researchers in engineering departments or research laboratories can obtain patent information related to the products and technologies they are in charge of. As an information sharing tool with excellent visibility, it can be a high value-added service that deepens information sharing between team members and members of the team's upper-level organization.

In addition, display processing is performed in an on-premises environment, which is a physical server prepared within the company, or in a private cloud virtual server environment for the core of the system, such as the patent evaluation database 30 and the database management unit 33, which requires a high degree of security. A configuration in which the server 3 is divided is also conceivable, such as implementing the unit 34 and the update processing unit 35 as an application program for each client terminal, or installing them as an application in a virtual server of a public cloud.

It should be noted that the present invention is not limited to the above embodiments, and can be modified as appropriate without departing from the scope of the invention.
