And an output step of receiving the ID of the search result patents and the related number from the cited patent search means and the citation count calculating means, respectively, and outputting the interlocked patents.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

First, referring to FIG. 1, the seed patent, the preceding patent, the following patent, the collateral patent, and the number of citation relationships described in the present invention are as follows.

The rectangular boxes shown in FIG. 1 each mean one patent, and the arrow connecting each box indicates the direction in which the arrow refers to the prior patent. In other words, Patent I shows a pre-patent relationship in which Patent G is a prior patent and Patent M cites Patent J as a prior patent. In addition, each alphabet is introduced for description of the present invention as an ID to a specific patent. Thus, in practice, this may be replaced with a publication ID, a registration number, or a unique ID to identify the patent.

For reference, in the present invention, the term "patent" may refer to the invention of the application not only registered patent but also to the present disclosure, and further, all points that can be formed in the line-of-support relationship such as utility model, design, trademark, etc. It is representative of property rights. In general, such citation relations are generally selected at the substantive examination of the respective patent offices, but may include prior patents directly mentioned by the applicant in the Information Disclosure Statement (IDS) existing in the US patent system.

After the user of the present invention finds certain specific patents, he or she may wish to find out the citation relationship of these patents. In other words, a plurality of patents having a specific applicant or a specific technical classification are found through a search, and then a post-patent patent which refers to which patents as prior art patents or to cite these patents as prior art (hereinafter, ' Later patents' are intended to determine what is there.

In this case, since the specific patents are the starting grounds for the citation relationship investigation, this is specifically referred to as a seed patent or seed patent group, and in FIG. 1, patents J, K, and H existing in a closed curve made of dotted lines are seeded. Patents.

Therefore, if the interpretation of the relationship of Figure 1 again, for patents J, K, H, patents G, D, and F will be prior patents, and patents M and L will be later patents citing seed patents as prior patents. will be.

 In addition to these preceding and following patents, the present invention introduces a new concept of patent citations called collateral patents.

In the present invention, the collateral patent refers to a patent that is not directly connected to seed patents, but is indirectly connected to it through a preceding patent or a following patent. For example, in FIG. 1, G which is a prior patent of seed patent J For another patent I to cite this as a prior patent at the same time, patent I is in patent relationship with patent J through patent G. As another example, seed patent J, K or H has patent L as a trailing patent, patent C also has patent L as a trailing patent, so patent C is a collateral patent of seed patents. Patent N has collateralized with seed patents through following patent L and prior patent F.

The reason why analysis of collateral patents is necessary is that the collateral patents cannot be searched by the pre-supply relationship of the seed patents, but because they have the same precedent or subsequent patents as the seed patents, they are considered to be filed at the same or similar time as the seed patents. And may further be placed in technically equivalent or replaceable relationships with the seed patents.

In FIG. 1, the numbers recorded on the upper portions of the patents refer to the number of times a direct or indirect relationship with the seed patents is established. Specifically, in the case of the preceding patent, the number of times cited from the seed patents, and in the case of the following patent, refer to the seed patents. The number of citations and, in the case of collateral patents, refers to the number of indirect relationships with seed patents. For example, collateral patent I is indirectly linked to seed patents through patent G and patent F, so the indirect relationship is 2 and patent F is cited only once from seed patents although it is relatively cited. The number is one.

The number of citations, citations, or indirect relations refers to the degree of relationship with seed patents. The higher the number, the higher the precedence, trailingness, or substitution of seed patents. Can be a very important indicator.

Hereinafter, specific embodiments of the present invention will be described using the above-described relationship of FIG. 1 as an example.

Example 1 Method of Performing Multiple Citation Analysis Directly from a Patent Database

FIG. 2 is a block diagram showing the components of the patent information system required by the first embodiment for each module. FIG.

In order for the present invention to be applied, at least two or more patents among patents stored in the patent database shown in FIG. 2 should be stored in association with information on their prior patents. That is, the present invention relates to a patent analysis system and method for finding prior patents, following patents, or collateral patents for at least two or more plurality of patents.

The operation of the cited patent search means and input unit of FIG. 2, and the number of citation counting means is described in detail in the flowchart illustrated in FIG. 3.

Referring to FIG. 3, the cited patent search means first undergoes an input step of receiving IDs of at least two seed patents from an input unit.

The input unit refers to hardware such as a keyboard, a mouse, and / or a software module such as the input window, which is used in a method of listing and inputting a patent number in a search window of a computer screen provided by a general patent database.

As described above, the seed patent ID is a basis for the user to analyze the citation relationship. The seed patent ID corresponds to a unique number of a patent such as an application number, a publication number, and a registration number of the patent.

The user can then select, by the analysis mode setting means, a citation relationship to be analyzed by at least one of the preceding citation relationship of the preceding patent of the seed patent, the following citation relationship of the following patent, or the collateral citation relationship of the collateral patent. Go through the steps

This analysis mode setting means is necessary to specify the object to be analyzed in an integrated type analysis system that enables various citation analysis with one system, but separate analysis systems for prior patents, trailing patents, or collateral patents, respectively. If the structure is separated from each other by a prior patent citation relationship analysis module, a subsequent patent citation relationship analysis module, or a collateral patent citation relationship analysis module, the search mode setting means may not be necessary separately in each analysis module. In addition, even in the integrated form, if it is set to perform all the preceding, trailing, and collateral by default, it may not be necessary separately.

For reference, the seed patent ID input and analysis mode setting may be inputted in reverse order. That is, first, set the analysis mode, and then input the seed patent ID.

The citation patent search means is a means for finding other patents in the citation relationship based on the seed patent ID, which is usually composed of software and coupled to the analysis system of the present invention. Of course, hardware-configured forms are also available.

In the case of selecting a prior cited relationship in the analysis mode, the cited patent search means goes through a search step of searching for and finding from the patent database the preceding patents cited by the seed patents based on the IDs of the seed patents provided. That is, since each patent recorded in the patent database of the present invention has a record of its own prior patent, the cited patent search means searches the prior patent of the seed patents directly from the database in real time.

Then, the citation count calculation means, which is also configured in software or hardware form, and calculates the number of citations cited by the seed patents for each of the preceding patents found in the step by the citation count calculating means coupled to the analysis system of the present invention. Go through the steps

This is to find out the relationship shown on each patent ID by the Arabic numeral of FIG. 1 mentioned above.

Finally, the output means such as a PC monitor under the control of the CPU and the OS and the driving driver are provided with the IDs of the preceding patents and the number of citations, respectively, from the citation patent search means and the citation count calculation means. Output step is performed.

If the user sets the analysis mode to a trailing cited relationship in the integrated analysis system, the cited patent search means retrieves the trailing patents citing the seed patents from the patent database based on the provided seed patent IDs. After searching by searching, the output is processed through the same process.

If the analysis mode is for collateral citation, the cited patent search means first finds the prior patents cited by the seed patents based on the provided seed patent IDs, and the patent group citing these prior patents as prior patents. Find them. This is because it is found in a different way from the collateral patents found from the following patents to be described later, it is called a first collateral patent when it is particularly necessary to distinguish the two. The first collateral patent group may also include the seed patents, but since it is desired to know the collateral relationship of the seed patents, only the pure first collateral patents may be found through the step of filtering and removing only the seed patents. .

In addition, in order to find a collateral patent group connected indirectly with a subsequent patent among collateral patents, the citation patent search means first searches for the following patents citing the seed patents based on the seed patent IDs provided, and then the following patents Find a patent group cited as a prior patent. The patent group found for classification is referred to as a second collateral patent group. In the present invention, the method of finding the collateral patent group may use a method of finding at least one or both of the first collateral and the second collateral group.

Then, the citation count calculation step for calculating the citation count relationship with the seed patents for each of the patents belonging to at least one of the first and second collateral group patents; Go through.

Next, the output unit receives the IDs of the collateral group patents for which the collateral citation number is calculated and the collateral citation number from the cited patent search means and the citation count calculating means, respectively, and outputs the interlocked citations. Perform.

Example 2 Method of Performing Multiple Citation Analysis from Citation File

In the citation relationship analysis of the present invention, the above-described embodiment should search the patent database in real time every time the analysis, and accordingly, if the same and similar analysis is newly performed every time the database is updated, the server load increase and the communication with the server. Discomfort due to slow speed can be expected.

As a countermeasure against this problem, the second embodiment of the present invention generates a citation file for patent data from a server in advance and stores it in a storage device connected to a server or a storage device connected to a terminal such as an analyst's PC. It is about how to analyze. Therefore, in this case, if there is a database update, such as the publication of new patent cases, a new citation file is generated only for the update cases, so that the load on the server can be reduced and at the same time, it can be quickly analyzed.

4 is a block diagram illustrating a citation file generation module of the present invention for such an embodiment, and FIG. 5 relates to an analysis module using the generated citation file.

Referring to Figures 4 and 5 the operation method in detail as follows.

First, a connection step of connecting a citation file generating means to a patent database in which information of patents is stored is performed.

The citation file generating means receives the ID and the preceding patent ID cited by these patents for a predetermined patent, that is, all or a large number of patents recorded in the database, and sets the predetermined patent ID as a file name therefrom. A citation file is generated using the prior patent ID as a file content.

FIG. 6 illustrates an example of the citation file generated as shown in FIG. 1. For example, in FIG. 1, since patent M has patents J and N as prior patents, while a citation file called M.SPT is generated, the contents of the file are recorded as J and N, and so on. Where the extension SPT is an arbitrary notation to show that the cited file of this embodiment is in file format.

The citation file generating means then stores the citation files in the citation file storage device. Here, the citation file storage device may be another storage server connected to a server where the database exists, or a storage device such as an internal or external hard disk connected to a user's terminal, for example, a PC.

The generation of the citation file may generate and store a new citation file every time an update is added to the patent database with data about the new patents by application or publication of a new patent.

After creating the citation file through these steps, a detailed analysis step is performed thereafter.

When the analysis begins, the citation file search means first retrieves the IDs of the seed patents with a command to find the IDs of at least one patent group of at least one of the preceding patents, the following patents, or the collateral patents of at least two seed patents. The input stage is provided from the input unit. In this case, the analysis mode setting means may receive the at least one or more of the preceding patent, the following patent, or the collateral patent, and notify the cited file searching means. It operates as a partial module that is included or at least connected, so that the citation file retrieval means can be broadly inclusive of the analysis mode setting means.

If a predecessor is selected as the mode to be analyzed, the citation file searching means goes through finding the citation files with the file names corresponding to the IDs of the provided seed patents from the storage device. For example, in FIG. 1, when the seed patents are J, K, and H, files J.SPT, K.SPT, and H.SPT are found from the cited file storage device.

Then, the output means goes through an output step of outputting file contents from the found citation files as prior patent IDs of the seed patent. That is, the contents of the files J.SPT, K.SPT, and H.SPT are read, and G, D, and F are output to a monitor or other output device as prior patents for seed patents J, K, and H.

In addition, before the output step, the citation count calculation means may calculate the citation count as the duplicate count of the duplicated patent case among the read file contents and provide the citation count to the output device so that the citation count or the duplicate count may be output together. For example, if the read file contents are G, D, D, and F, the number 2 is output together at the output indicating the patent D. Of course, a method of outputting the number 1 as a duplicate number may also be included in patents that do not overlap.

If the selection in the analysis mode is for the following relation, after the citation file is generated and stored, the citation file search means stores the citation files having the file contents corresponding to the IDs of the provided seed patents from the storage device. The finding step and the outputting means go through an output step of outputting file names of the found citation files as trailing patent IDs of the seed patent. For example, in FIG. 6, in the case of finding the following patents M and L for the seed patents J, K and H, the cited files having the IDs of the seed patents J, K and H as file contents, that is, M.SPT and L. It finds the SPT and prints the file names M and L. You can also calculate the number of duplicates and print them out together.

If the selected one in the analysis mode is for a collateral relationship, after the generation and storage of the citation file, the citation file search means includes a first citation file having file names corresponding to IDs of the seed patents provided from the storage device. In the case of FIG. 6, for example, the files J.SPT, K.SPT and H.SPT are found and prior patent IDs, namely, G, D and F, which are file contents of the cited files belonging to the first cited file group, are read. Then find a second cited file group, namely G.SPT, D.SPT and F.SPT, having the same file name as these patent IDs, and find the file names of the cited files in this second cited file group, namely G, D, A first search is performed to find a third cited file group having the same file content as F, namely I.SPT and J.SPT, K.SPT and H.SPT, N.SPT.

Further, in addition to the first search, the citation file search means includes a file name of the citation files belonging to the first citation group, that is, a fourth citation file group having the same file content as J, K, H, that is, M.SPT. And a fifth cited file group having the same file name as J, N, C, K, H, that is, J.SPT, N.SPT, finding the L.SPT and file contents of the cited files belonging to the fourth cited file group. A second search may be performed to search for C.SPT, K.SPT, H.SPT.

Then, the output means stores the file names of the cited files belonging to at least one of the third cited file group and the fifth cited file group, that is, I, J, N, C, K, H of the seed patent. An output step of outputting the patent IDs is performed.

If you want to find only pure collateral patents may be further performed by filtering the J, K, H from the seed patent to remove them.

A modification of the present embodiment relates to a method of generating a trailing relationship as a citation file this time when creating the citation file described above. That is, after going through the connecting step of connecting the citation file generating means to the patent database in which the information of the patents are stored in the above-described step, the patent of the predetermined patent and the following patent citing the predetermined patent from the patent database to which the citation file generating means is connected. After receiving the ID, the predetermined patent ID is used as a file name, and the subsequent patent ID is used as a file content. Therefore, in this citation file, the patent ID of the file name is made a prior patent of the patent ID which is the file content.

Then, while the citation file generating means stores the citation files in the citation file storage device, the citation file generation and storage step is completed.

When a citation relationship analysis is started and analysis is started to specify seed patents and to find prior patents of seed patents, first, the citation file search means includes a command to find a prior patent ID of at least two seed patents. Together, the seed patent IDs are input from the input unit.

The cited file searching means then finds the cited files having file contents corresponding to the IDs of the provided seed patents from the cited file storage device, and the output means searches for the file names from the found cited files. The step is completed by going through an output step of outputting as following patent IDs.

The process of finding trailing patents of seed patents using a citation file describing such a trailing relationship is as follows.

Firstly, a connection step of connecting a citation file generating means to a patent database storing information of patents and a ID of a predetermined patent and a subsequent patent ID citing the predetermined patent are received from the patent database to which the citation file generating means is connected. The step of generating the citation file having the predetermined patent ID as the file name and the content of the trailing patent ID as the file contents and the step of storing the citation files in the citation file storage by the citation file storage means are the same as in the previous embodiment.

Next, the cited file searching means receives the ID of the seed patent from the input unit together with an instruction to find the following patent IDs of at least two seed patents, and the cited file searching means is provided with the seed. Finding a trailing patent through a step of finding citation files including IDs of patents as file names from the citation file storage device and an output step of outputting file contents of the found citation files as trailing patent IDs of the seed patent. Done.

The process of finding collateral patents of seed patents using a citation file describing such a trailing relationship is as follows.

Firstly, a connection step of connecting a citation file generating means to a patent database storing information of patents and a ID of a predetermined patent and a subsequent patent ID citing the predetermined patent are received from the patent database to which the citation file generating means is connected. The step of generating the citation file having the predetermined patent ID as the file name and the content of the trailing patent ID as the file contents and the step of storing the citation files in the citation file storage by the citation file storage means are the same as in the previous embodiment.

Next, when the citation file searching means receives the IDs of the seed patents from the input unit with a command to find the collateral patent IDs of at least two seed patents, the citation file searching means is stored from the citation file storage device. Find the first cited file group having the file names corresponding to the IDs of the seed patents provided, read the trailing patent IDs which are the file contents of the cited files belonging to the first cited file group, and have the same file names as the following patent IDs. The first citation file group includes a first search and the citation file search means for finding a second citation file group and searching for a third citation file group having the same file contents as the file names of the citation files belonging to the second citation file group. Find the fourth cited file group having the same file content as the file name of the cited files belonging to the cited file group. At least one of the third cited file group and the fifth cited file group is performed by a searching step and output means for performing at least one or more of the second searching for searching the fifth cited file group having the same file name as the file contents of the file. Through the output step of outputting the file names of citation files belonging to one or more groups as the collateral patent IDs of the seed patent, the collateral patents are manifested.

Even when the preceding, trailing and collateral patents of the seed patents are found by using the citation file describing the following patents, the number of citation relationships can be calculated before the outputting step and outputted together. In addition, the citation files described in the following patents described above may be performed to update the file contents of related citation files whenever a new subsequent patent is filed or published.

In the present invention, the citation file may be a file describing all of the preceding patent, the following patent, and the collateral patent as follows.

That is, when the citation file for a given patent is generated, a comprehensive citation file including the preceding patent and the following patent and, if necessary, the collateral patent ID is generated. Hereinafter, this is referred to as a comprehensive citation file for classification.

Such a cited file can be created by the cited file generating means described above. The process is based on the ID of a given patent, and searches the patent database based on this to find the IDs of the preceding patents and the following patents. In the case of addition, the patents related to the above-described collateral relations for each of the found prior patents and the following patents are additionally searched, and their IDs are described as file contents of the comprehensive citation file and stored in a storage device.

Then, when the ID of the seed patents is provided, and before and after this, the command is issued to search for and output at least one group of the preceding patents, the following patents, and the collateral patents. After finding a comprehensive citation file and recognizing the contents of the file, it extracts the IDs of the preceding patents, the following patents or collateral patents according to the given citation mode and outputs them to the output device. It is also possible to add a step for counting the number of citations before output, and these collective citation files can update the files corresponding to the case of a new application or a published patent.

FIG. 7 illustrates an example of a comprehensive citation file made for each patent using the case of FIG. 1. The file name of each file consists of the ID of the relevant patent, and each file content is divided into three areas, where the first area contains the preceding patent ID, the second area the following patent ID, and the third area, if necessary, the collateral patent ID. Consists of

FIG. 8 shows an example of a citation relationship analysis screen outputted by analyzing the example of FIG. 1.

FIG. 8A shows IDs of preceding, following, and collateral patents based on seed patents, and shows seed patent IDs and their names, and FIG. 8B shows a case in which seed patents are excluded from the collateral patent list of FIG. 8A. In this case, among the seed patents, it may be displayed without being excluded in the case of a preceding or following patent of another seed patent.

In the display of the patents, when the ID is clicked with a mouse or the like, each ID or the like may be hyperlinked so that the contents of the patent are displayed.

8c shows, for example, a list of prior patents of seed patents and the number of prior citations cited from seed patents. Subsequent patents or collateral patents can of course be displayed in the same manner.

Example 3 Multiple, Multi-Step Citation Analysis Method

Another embodiment of the present invention relates to a method for finding a patent that is designated as a prior patent or a following patent primarily from a seed patent, as well as the following patent of the preceding or following patent of this prior patent.

Specifically, this process starts with an input step of receiving IDs of at least two or more seed patents from the input unit before and after the step where the citation patent search means is to be analyzed, i.e., receiving the citation relationship order. Herein, a step or a degree means a reference distance from a hierarchy of seed patents or seed patents for a seed patent in a manner of setting a prior patent of a seed patent as a primary and a prior patent of the prior patent as a secondary ( distance of reference).

Then, the cited patent search means goes through a search step of searching for and finding from the patent database the preceding patents cited by these patents or the following patents or collateral patents citing them based on the patent IDs provided in the previous step. Execution is repeated as many orders. The preceding patents, following patents, and collateral patents have the same concept as those of the above-described embodiments.

Next, the cited patent search means stores the preceding patents, the following patents, and the collateral patents retrieved in the previous step in a storage device by interlocking each preceding order, which is stored in a temporary storage device such as RAM or a hard disk. The concept includes all storage devices.

Then, the number of citation counting means determines the number of times the preceding patent, the following patent, and the collateral patent have been cited or cited by the seed patents, or indirectly related, that is, the number of common patents or trailing patents. The citation count calculating step and the outputting means for calculating are provided with the ID, order and the number of citations of the preceding patents respectively from the citation patent search means and the citation count calculating means, and then output the interlocked outputs.

The present invention relates to a method of operating a patent analysis system or a patent information system for finding patents that are indirectly linked through the preceding patents, the following patents, or the prior support by using seed patents as starting points. .

By using the present invention, when only some of the patents to be found are known, the patents to be searched can be accurately and easily found using the patents of some of them.

This method of operation of the present invention is used as a means for extending patents from seed patents, and this extended patent group is again divided into cases having the same applicant, inventor or IPC, UPC, F-term, etc. as the seed patents. If the subsequent process of reducing the patent reduction means, etc. continuously through it has the advantage that a more accurate patent search is possible than the conventional simple word search method.
