Description

[0002] A visualization system for claims relationship among patent documents,

The present invention relates to a rights relationship visualization system for extracting keywords included in claims of at least two or more patent documents and visualizing a patent rights relationship between patent documents using the extracted keywords.

Generally, in the patent document, the claim scope is the part that describes the rights of the patented invention, and it is the most important part in analyzing the rights contents that can be exercised as the patent document. Therefore, by analyzing the scope of claims of a patent document, it is possible to know a specific scope of rights or a rights object for a patent document. In addition, by analyzing the claims of a company's patent documents, the company's technology portfolio can be known.

In particular, each company and research group, or country, is changing from a quantitative growth of patents to building a strategic patent portfolio to secure superior patents. In other words, as intellectual property rights are recognized as major achievements of economic activities rather than as a byproduct of R & D, they are expanding into M & A, competitor technology analysis, and technological enhancement.

In other words, through analyzing the patents held, we will build a portfolio by understanding what kind of patents are currently held by the organizations or companies, and what key elements and technological solutions are used for each patent. Based on these patent portfolios, it can be used as a basis for strategic decision-making on establishing additional research and development plans and acquiring technology. In addition, each institution or company can analyze the patent portfolio of the competitive market, the competitor, or the competing country, and can grasp the technical situation of the competitor in a more detailed manner and derive an advantage strategy in the competitive market.

However, it is not possible to analyze the core components of the individual patents in the database constructed through the existing patent documents, and thus the system between the components can not be visualized. Thus, patent experts often work on a one-to-one basis when comparing the scope of rights. However, it is very complicated and difficult to grasp the right relationship at once because patent experts must analyze each patent document in detail while reading it. Further, there is a problem that it takes much time and cost. Therefore, for this reason, it is impossible to present the visualized component, or it takes a lot of time and cost, so that it is not utilized in strategic patent management through patent data.

In order to solve the above problems, a technique for visualizing the claims is proposed (Patent Document 1). However, the prior art analyzes and visualizes the relationship between the claims set forth in the claims, the morphemes of the claims, and the like for only one patent document. In addition, technologies for extracting constituent elements and technical solution means of the claims are proposed [Patent Document 2]. According to the form of the patent claim, there is a technique of dividing into independent clauses, dependent clauses, extracting the core components described in claims, and separating the phrases describing the functions of each core component.

However, all of the above prior arts are techniques for analyzing a patent claim with respect to a single patent document, and it is very difficult to apply it to a technology for analyzing a large number of patent documents, that is, a patent portfolio.

Patent Documents 3 and 4 disclose methods for extracting and displaying relationships among a plurality of patent documents by analyzing a plurality of patent documents and deriving associations based on keywords among documents, . In other words, these technologies are not subject to the analysis of patent claims themselves, and therefore, it is difficult to apply them to techniques for analyzing mutual relations based on claims.

Therefore, in order to analyze the patent portfolio, there is a desperate need for techniques for comparing a plurality of patent documents against the patent claims.

[Patent Document 1] Korean Published Patent Application No. 2011-0020115 (published on Mar. 2, 2011) [Patent Document 2] Korean Published Patent Application No. 2014-0022286 (published on April 24, 2014) [Patent Document 3] Korean Registered Patent No. 1268503 (Announcement 2014.06.04) [Patent Document 4] Korean Published Patent Application No. 2011-0010664 (Published on February 21, 2011)

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, the present invention will be described in detail with reference to the drawings.

In the description of the present invention, the same parts are denoted by the same reference numerals, and repetitive description thereof will be omitted.

First, an example of the overall system configuration for carrying out the present invention will be described with reference to FIG.

As shown in FIG. 1, the rights relationship visualization system 30 between patent documents according to the present invention can be implemented as a server system on a network.

1, an example of an overall system for implementing the present invention comprises a user terminal 10 and a rights relationship visualization system 30 and is connected to a network 20 with each other. It is also possible to further include a database 40 for storing necessary data. In addition, a patent search system 50 for searching patent documents is connected to the network 20. That is, the rights relationship visualization system 30 between patent documents according to the present invention can be implemented as a server system on a network.

More specifically, the database 40 is for storing data, and the database 40 comprises a patent document DB 41 for storing patent documents and a keyword DB 42 for storing keywords in patent documents . However, the configuration of the database 40 is only a preferred embodiment. In the development of a specific device, the database 40 may have a different structure in consideration of ease of access and retrieval, efficiency, and the like.

Here, the database 40 is set to be used by the patent search system 50 and the rights relation visualization system 30 together. It is possible to configure a separate database for each system 30, 50.

The patent document refers to a published patent publication or a registered patent publication. Patent documents can include not only patents but also utility models. Since the utility model is almost the same as the patent specification, only the contents of the utility model are the same. Therefore, when referring to the patent document, the utility model publication shall also be included in the following. On the other hand, the patent document DB 41 includes both domestic and foreign patent publications. That is, all patent publications issued by national patent offices or WIPO are covered.

Also, in the database 40, the patent document is configured such that the bibliographic item, the configuration of the patent document, etc. are all managed as data items and can be searched or referenced as corresponding items.

In addition, the database 40 constructs or generates a DB for storing data for patent search or right analysis of a patent document in addition to a patent document. Particularly, the patent document DB 41 can be divided into a master DB and a user DB, and the result of searching or classifying by the user can be temporarily constructed in the user DB. As described above, the patent document DB 41 is separated and processed so that the speed improvement and stable DB processing can be performed.

In addition, the database 40 constructs and stores data on the keyword for the patent document in the keyword DB 42. Similar relationships among keywords are also set in advance and managed as data. Therefore, when the user selects any one of the keywords, the keywords (in the similar relationship) associated with the keyword are retrieved, and both the keyword and the similar keyword can be used.

At this time, at the time of constructing the data of the keyword DB 42, the keyword may be divided into keywords corresponding to the components of the claim, keywords for the entire range of the claims, and keywords for the entire range of the patent document. In addition, the keywords included in each patent document can be extracted and managed for each patent document.

Particularly, preferably, the similar keywords are composed of a similar group (a set of similar keywords) which is a set. For example, {motors, motors, motors, motors, motors} are all similar keywords and constitute one similar group (a set of similar keywords). Preferably, the representative keyword for the similar group may be predetermined. In the above example, "electric motor" can be set as a representative keyword.

In one embodiment, the rights relationship visualization system 30 constructs a result (or a population of patent documents) pre-searched or classified in the patent search system 50 in the user DB, You can refer to the stored DB only and display the result on the screen.

In another embodiment, when storing a patent document classified by the rights relationship visualization system 30, it is possible to classify and store only the identification information of the patent document without storing all information of the patent document. In other words, when you want to see the specific contents of a patent document searched or classified as a population, you can access the contents of the patent document by using the identification information of the patent document.

Since the functions of the database 40 can be implemented using a conventional database technology, a detailed description of the implementation will be omitted.

The patent search system 50 refers to a conventional patent search system. According to the present invention, an object to analyze a patent document should be selected. For example, the patent document may be all patent documents filed by a specific company, entire patent documents belonging to a technical classification such as an IPC classification, or a patent document of a search result searched by a search term. The patent documents that are selected and analyzed by the user are referred to as patent document populations or populations.

In an embodiment of the present invention, it is assumed that the result searched by the patent search system 50 is analyzed. This enhances convenience to the user when the user simultaneously supports the patent search system 50 and the rights relation visualization system 30. [ The reason for this is that the user can analyze and analyze the retrieved result, and then perform a detailed search in order to obtain a more detailed knowledge of the patent document. Therefore, it is possible to perform more effective patent analysis by repeating the patent search and the right analysis.

However, the rights relation visualization system 30 according to the present invention is not limited to the search result by the patent search system 50. The rights relationship visualization system 30 may perform an analysis of the rights on the already determined patent documents.

The user terminal 10 is a typical computing terminal such as a PC, a notebook, a netbook, a PDA, or a mobile, which is used by a user who performs patent analysis. The user inputs commands such as selecting keywords in a population or selecting patent documents using the user terminal 10, and transmits the commands to the rights relationship visualization system 30, or transmits the analyzed results to the rights relationship visualization system 30, . Also, the user terminal 10 displays the results received on the display screen.

The rights relationship visualization system 30 is connected to the network 20 as a normal server and provides a service for analyzing the scope of rights for a patent document. In addition, the rights relationship visualization system 30 provides a service for displaying the analyzed result in a two-dimensional image format such as a diagram or a graph. At this time, the rights relationship visualization system 30 transmits the results to be displayed on the display screen of the user terminal 10.

On the other hand, the rights relation visualization system 30 can be implemented as a web server or a web application server that provides the above services as web pages on the Internet.

Next, a configuration of a rights relationship visualization system between patent documents according to a first embodiment of the present invention will be described with reference to FIG.

Referring to FIG. 2, the patent document visualization system 30 according to the first embodiment of the present invention includes a population setting unit 31, a keyword configuration unit 32, a keyword filter unit 33, And a visualization unit 34. The filtering unit 35, the grouping unit 36, and the viewer unit 37 may be additionally provided. In addition, it may further comprise a database (or storage space) 40 for storing data.

The population setting unit 31 sets a population of patent documents for visualizing the rights relationship. Preferably, the population setting unit 31 receives the set of patent documents and sets the entire patent documents as a population.

That is, the population of a patent document refers to the entire data set of the patent documents to be analyzed. As described above, the user can set, as a population, patent documents searched through the patent search system 50, classified or selected patent documents. For example, patent documents may be selected as a population based on the filing year, the filing country, the technical classification, the applicant, and the key patent. That is, the population is a search result based on a user's own construction or a search expression. The scope of the population may be limited to options such as the filing year, the applicant, the applicant's nationality, the IPC, the technical classification, the filing country, and the key patent status.

The user can input the patents selected through the search operation using the patent search system 50 or the like and directly set them as the population or input the predetermined patent document list data and set the patent documents as the population.

Next, the keyword constructing unit 32 constructs keyword summation of all the patent documents included in the population. Preferably, the keywords contained in each patent document are retrieved from the keyword DB 42.

In this case, the keyword collection sum may be constituted by the constituent elements of the claim, the entire keyword of the claim, or one of all the keywords of the patent document according to the user selection. That is, the keywords are divided into the following three methods.

The first method (or the element-based method) extracts only the keywords included in the elements of the claim. The second scheme (or the scheme based on the entire claim) extracts only the keywords included in the entire claims. In addition, the third method (or the entire document-based method) may extract a keyword included in the entire patent document to form a keyword summation sum. The keyword aggregation sum extracted by the first, second, and third schemes will be referred to as the keyword aggregation sum of the first, second, and third schemes, respectively.

A component means a technical matter of the claim, for example, when there is a claim of "a device comprising A, B including b1 and b2, and C including c1 and c2" including a1 and a2, A, B and C can be regarded as components. In addition, the keyword included in the entire claim means all the keywords of the claim including the component, and includes a1, a2, A, b1, b2, B, c1, c2 and C in the preceding sentence.

Further, the keyword construction unit 32 extracts keywords from the patent documents of the population, and calculates and stores the frequency (hereinafter, appearance frequency) of the keywords appearing in the patent documents. That is, the extracted keywords are referred to as a keyword summation sum, and each keyword included in the keyword summation sum has a value (or an attribute value) of occurrence frequency.

Next, the keyword filter unit 33 selects a plurality of keywords from the keyword aggregation sum, and extracts patent documents including the selected keyword (hereinafter referred to as reference keywords) from the population. That is, the keyword filter unit 33 receives the user's selection and selects the keywords selected by the user as reference keywords.

Preferably, the keyword filter unit 33 presents keywords having a high appearance frequency in the keyword aggregation sum to the user terminal 10 as a list, and selects keywords from the keyword list. The selected keywords are referred to as reference keywords. In particular, a descending order is sorted in descending order of frequency of occurrence, thereby presenting a list of keywords for keyword aggregation. In addition, only the keywords up to a predetermined rank (for example, a predetermined rank, for example, the top ten) may be presented in the keyword list of the collective agreement.

Further, the selection of the reference keyword can be performed through the search. That is, the user may perform a keyword search on the keyword aggregation sum, and the reference keyword may be selected from the retrieved result. In addition, the reference keywords can be selected using both the search method and the list presentation method described above.

On the other hand, a keyword list is presented from the keyword aggregation sum of the first, second and third schemes according to the first, second and third schemes described above, and the keywords selected from the presented list are selected as reference keywords.

In addition, the keyword filter unit 33 may include similar keyword data (or thesaurus data) matched with the reference keyword, and may include a similar keyword in the reference keyword. That is, a similar keyword relation can be established by receiving a user's input.

When the keyword aggregation sum is generated, the keyword is listed according to the frequency of appearance of the keyword, and the similar keyword data matching with the listed keyword is fetched. Among them, the user may include a desired keyword (selected by the user) and include the keyword specified in accordance with the frequency of appearance and a similar keyword corresponding thereto. And extracts the corresponding patent documents from the population through the keyword filter unit 33 including the similar keyword.

In the example of FIG. 5, when referring to the keyword setting portion, 'battery' is a keyword listed portion according to the keyword appearance frequency, and 'keyword', 'battery', 'battery' to be. At this time, the one that is pre-built in the keyword DB 42 for the similar keyword is used.

More specifically, when there is a reference keyword "motor", thesaurus data corresponding to this "motor" is fetched. At this time, there is a patent document including the keyword " motor ". If additional synonym choices are made here by the user, for example, if the user selects " motor " as a synonym for " motor, " That is, in this case, the patent document including the " motor " and the patent document including the " motor " are extracted from the population (as the patent document including the reference keyword).

That is, firstly, the reference keyword is listed, and then each second term corresponding to the reference keyword first listed in accordance with the user's selection is further selected. Then, a patent document including a synonym selected secondarily by the user is added and extracted.

Preferably, when the similar keyword is retrieved from the keyword DB 42, the retrieval is performed only when the similar keyword is a keyword included in the keyword recall sum. For example, when the similar keyword of "motor" is "motor "," electric motor " That is, only the similar keywords existing within the keyword summation sum of the patent documents present in the population to be visualized are selected and displayed.

Next, the visualization unit 34 displays the patent documents extracted by the keyword filter unit 33 in correspondence with nodes on the screen, displays the keywords included in each patent document on the screen, And edges connecting the nodes corresponding to the patent document including the keyword are displayed. Preferably, the edge is indicated by a straight line. More preferably, the edge is indicated by a dotted line.

On the other hand, if the keywords are the same or similar, only one keyword is displayed on the screen. For example, only one "motor" keyword is displayed on the screen, and "motor" and "motor" keywords selected by similar keywords are not displayed. Accordingly, if two or more patent documents displayed as nodes on the screen include all one keyword, intuitively know that the patent documents are indirectly connected to the edge through the keyword.

Preferably, if the patent documents extracted by the grouping unit 36 are classified into groups, the visualization unit 34 displays all patent documents belonging to the same group in an area representing a set (hereinafter referred to as a set area). More preferably, the visualization unit 34 displays the name of the group (the name of the group corresponding to the collection area) in the collection area. Further, the collective area is represented by a polygon such as a circle, a rectangle, or a rounded rectangle, and a node is displayed within the polygon of the collective area.

Preferably, the visualization unit 34 may display an aggregate area of the lower group within the aggregate area of the upper group according to the hierarchical structure of the group. The group is formed by the grouping unit 36 described below.

Further, the visualization unit 34 highlights the common keyword when any one of the keywords (hereinafter referred to as a common keyword) is included in the patent document belonging to different groups.

In addition, the visualization unit 34 displays keywords excluding the reference keyword among the keywords included in the extracted patent document on the screen. Herein, the keyword excluding the reference keyword among the keywords included in the extracted patent document will be referred to as a display candidate keyword. Among the display candidate keywords, a keyword actually displayed on the screen is referred to as a display keyword. When the display candidate keyword is too large, it is difficult to display all of the display candidate keywords, so that only important keywords among the display candidate keywords can be extracted and displayed on the screen.

Preferably, the visualization unit 34 can select display keywords among display candidate keywords according to a user's input. That is, the display candidate keywords are presented and the keywords selected by the user are selected as the display keywords.

Alternatively, as another embodiment, the visualization unit 34 can select a display keyword from among display candidate keywords by predetermined logic (or rule). For example, keywords included in at least two patent documents are selected as display keywords. Or the keywords included in all of the patent documents belonging to at least two or more different groups are selected as display keywords.

In addition, the visualization unit 34 can define a similar keyword among the display keywords displayed on the screen by selecting the drag-and-drop type of the user. Preferably, when one display keyword is dragged and dropped on another display keyword, a similar keyword relationship is established between the dragged keyword and the drop target keyword. At this time, one of the two keywords, which are similar keyword relationships, is deleted on the screen, and only the remaining one is displayed on the screen as display keywords.

That is, although the keywords included in the patent documents belonging to different groups on the visualization screen are in a similarity relation, there may be a situation in which they are not displayed as common keywords. For example, when the keywords are not reflected in the keyword DB, or when the keywords do not reflect similarity in the keyword DB, the above situation may occur.

As shown in FIG. 3 (a), if the user recognizes that the 'motor' and the 'motor' are similar words and are not displayed as a common keyword, the 'motor' keyword can be dragged and dropped on the 'motor' keyword . Then, a similarity relation is generated based on the 'motor' keyword as shown in FIG. 3 (b). At this time, the generated similarity relation can also be utilized for updating similarity data between the keywords stored in the keyword DB.

Next, the filtering unit 35 filters the patent documents extracted by the reference keyword using the bibliographic items included in the bibliographic information of the patent document. That is, the visualization unit 34 filters patent documents displayed as nodes by using bibliographic information such as the name of the applicant and the invention.

Next, the grouping unit 36 selects a country, a technical classification (major classification), a technical classification (middle classification), an applicant, etc. to designate nodes to be output on the visualization screen,

Preferably, the grouping unit 36 may set the group to a plurality of layers (or depths). The layer (or depth) setting is to set the group that the user wants to see in the population to be visualized. In other words, it can be grouped into technical classification, applicant and country, and can be viewed as a visualization screen according to the viewpoints to be viewed by the user.

For example, the case is composed of multiple depths of A (country) - B (technical classification) - C (applicant). First, when A is selected, it is grouped according to the national bibliographic information of the population patent document. If the composition of the population patent document is 5 cases in the US and 3 cases in Korea, it is grouped as shown in Fig. 4 (a). In Fig. 4, keywords and edges are omitted and displayed.

 Next, when A (country) - B (technical classification) is selected, 3 of A technology and 2 of B technology are 5 in the United States, 1 in A technology and 2 in B technology in Korea They are grouped and displayed as shown in Fig. 4 (b).

At this time, A is an upper group, B is a lower group, and B is displayed in a form dependent on A. That is, groups can be classified hierarchically. All patent documents belonging to a specific group can be classified and grouped again. At this time, the group to be classified again to detail is referred to as a lower group, and the group to be classified is referred to as a higher group. The subgroup can be classified again as a subgroup of the subordinate level.

In the above example, A (country) - B (technical classification) - C (if applicant is selected) For example, if the United States (the best classification) In the A technology, each of the J technologies is grouped into five from A applicant to E applicant. At this time, as shown in FIG. 4 (c). FIG. 4 (c) shows only the United States as an example without showing the entirety.

Preferably, the filtering unit 35 receives the items to be filtered and filters the items with the bibliographic item, and the visualization unit 34 displays only the filtered patent documents on the screen again. Accordingly, the keyword and the edge are also reflected and displayed on the screen again.

Next, when a node is selected on the screen, the viewer unit 37 displays detailed information of the patent document corresponding to the node. Preferably, the detailed information includes at least one of bibliographic information, summary, claims, and specification of the patent document.

In addition, the viewer unit 37 displays the list of the patent documents on the screen when the overlapping keyword, that is, the common keyword, is clicked.

Next, the configuration of the screen displayed by the visualization system according to the present invention will be described more specifically with reference to Figs. 5 to 7. Fig. FIG. 5 shows an example of a full screen configuration displayed in the visualization system according to the present invention, and FIGS. 6 to 7 show a list of patent documents on the screen or exemplify rights relation matrices.

5, the screen displayed by the visualization system according to the present invention includes a population display screen (corresponding to the population setting unit 31 of FIG. 2) displayed on the leftmost side of the screen, a keyword display (Corresponding to the keyword filter unit 33 in Fig. 2), a right relation display screen (corresponding to the visualization unit 34 in Fig. 2) displayed on the center or right side, and a filtering display screen (Corresponding to the filtering unit 35) and a grouping display screen (corresponding to the grouping unit 36 in Fig. 2) displayed at the top of the rights relationship display screen.

The population display screen is a display of a population, and groups having a hierarchical structure in the population are displayed in a tree-shaped folder. At this time, the group is displayed in a hierarchical structure by the technical classification (IPC classification, etc.) of the patent document. In addition, an interface screen for filtering and setting a population by the bibliography of a patent document such as a filing year section, a country, and an applicant is provided. Also, preferably, a user setting interface can be provided so that the bibliography of the patent document can be set in more detail and filtered (classified or searched).

The keywords displayed on the keyword display screen include the keywords included in the keyword aggregation sum described above. Preferably, when the keywords are not the representative keyword by the similar group, an interface screen capable of further selecting a similar keyword on the keyword display screen can be provided.

Also, in the right relation display screen, a plurality of patent documents including all the reference keywords are displayed as nodes on the screen. As shown in the right relationship display screen of Fig. 5, the nodes of a plurality of patent documents are displayed as a collection area by a group. At this time, the group can be set on the grouping display screen.

In Fig. 5, the collective area is indicated by a circle for two groups, that is, for the A technology and the B technology group, respectively. And their group patent document nodes are displayed in the corresponding set area.

All or part of the keywords other than the reference keyword among the keywords displayed on the keyword display screen are displayed on the right relationship display screen. Display keywords displayed on the screen are not displayed with duplicate keywords. And forms an edge with a dotted line between the keywords and the node. At this time, a node and an edge corresponding to the patent document including the display keyword are formed. In addition, the display keywords "carbon material, iron sulfate, separation membrane ", and the like are keywords included in all the patent documents included in two different groups, and are displayed as highlighted red boxes.

In addition, the filtering display screen can provide an interface for selecting a keyword aggregation sum of the first or second scheme. In other words, there is an option to select whether the overlapping keyword of the visualization screen is 'perfect match' or 'match when including a thesaurus'. Alternatively, an interface for filtering patent documents displayed in the rights relation by bibliographic matters such as the applicant and the name of the invention is provided.

When the filtering elements are changed in the filtering display screen, the right relation display screen is changed in real time by reflecting these filtering elements.

Also, as shown in FIG. 6, if the overlapping keyword, that is, the shared keyword is selected, the list of patent documents including the corresponding shared keyword is displayed as a pop-up on the screen. Further, if a specific patent document is selected in the list, a detailed information screen (not shown) of the patent document selected by the viewer section 37 can be displayed.

In addition, as shown in FIG. 7, the right relationships including the keywords among the patent documents displayed in the rights relation can be displayed as a pop-up screen in the form of a two-dimensional matrix map. In addition, the two-dimensional matrix map can be provided so as to be downloaded in the form of a spreadsheet such as Excel, a database file, a word file, or the like.

Next, as an effect of the present invention, a rights relationship that can be analyzed by the visualization system will be described with reference to FIG. FIG. 8 shows example screens in which various rights relations can be displayed on the rights relationship display screen. Fig. 8 (a) illustrates the visualization of rights relations between applicants, Fig. 8 (b) illustrates visualization of rights relations between technical categories, and Fig. 8 (c) will be.

As shown in FIG. 8 (a), the distribution of the scope of own company or competitor right can be confirmed on the right relation display screen. In other words, L has a lot of lithium-based rechargeable battery technology, and it can be seen at once that S has not only lithium but also nickel and olivine rechargeable battery technology.

In addition, the possibility of infringement can be judged (similarity judgment). In other words, since both L and S have patents that include carbon materials, iron sulfate, and plasma components, there is a possibility of infringement between the two companies.

As shown in FIG. 8 (b), it is possible to grasp component elements / element technologies according to technical fields. A technology has a large distribution of lithium-based secondary battery technology, and it can be understood that the technology of B is distributed not only in the lithium series but also in the nickel and olivine series secondary battery technology.

In addition, you can identify component / element technologies that have interdependencies. Since the patents including carbon materials, iron sulfate, and plasma components are distributed both in the A technology and the B technology, it can be seen that there is a relation between the two technologies.

As shown in FIG. 8 (c), the distribution range of own company or competitor right can be confirmed. Company L mainly owns lithium-based technologies in the field of secondary batteries, and materials used in the field of cathode materials. Company S has developed nickel-based technologies in addition to lithium in the secondary battery field. In the field of anode materials, Technology.

In addition, it is possible to judge the possibility of infringement (judgment of similarity) by checking the distribution of the scope of right of own company or competitor. In the secondary battery sector, both L and S have patents that include carbonaceous component elements. In the cathode material field, both L and S patents contain iron sulfate and plasma components, There is a possibility of infringement between the two companies.

Next, a configuration of a rights relationship visualization system between patent documents according to a second embodiment of the present invention will be described.

The rights relation visualization system 30 according to the second embodiment of the present invention is the same as the rights relation visualization system 30 of the first embodiment. However, there is a difference in that similar keywords are managed as similar groups, and the sum of keyword aggregation is constituted by representative keywords of the similar keywords. Only the difference will be described below in comparison with the first embodiment. The rest of the specific configuration refers to the first embodiment described above.

The keyword construction unit 32 extracts all the keywords included in the patent documents on all the patent documents included in the population, and constructs a keyword collection sum. At this time, the keyword constructing unit 32 may determine similar keyword relationships to form similar groups. The keyword constructing unit 32 refers to the keyword similarity group stored in the database 40 and judges whether the extracted keywords are similar or not. That is, if two different keywords belong to one similar group stored in the database 40, the two keywords are similar keywords.

Therefore, the similar group formed by the keyword constituent unit 32 becomes a subset of the similar group of the database 40. [ That is, if only the keywords included in the patent document of the population are extracted from the similar group of the database 40 and a subset is formed, the corresponding subset becomes a similar group in the keyword aggregation sum.

If the keyword is a similar keyword, the keyword constructing unit 32 includes only the representative keyword in the keyword collecting sum. The representative keyword is determined in advance (for example, when the representative keyword is determined and stored in the database, the representative keyword is fetched from the database), and the keyword having the highest appearance frequency among the similar keywords in the patent document is determined. Or may be determined by the user.

For example, if the patent document 1 includes the keyword "motor" and the patent document 2 contains the keyword "motor", only the representative keyword "electric motor" is included in the keyword collection sum. And patent documents 1 and 2 both contain the same keyword "motor".

Therefore, when calculating the appearance frequency of the keyword, the keyword constructing unit 32 calculates the appearance frequency by assuming that the similar keywords are the same keyword in the case of the similar keyword. That is, the frequencies of appearance of the keywords belonging to the similar group are all calculated.

Next, the keyword filter unit 33 selects a plurality of keywords from the keyword aggregation sum, and extracts patent documents including the selected keyword (hereinafter referred to as reference keywords) from the population. At this time, in the case of a similar keyword, only the representative keyword is displayed or selected as the reference keyword. However, all the patent documents including the keyword of the similar group to which the representative keyword belongs are also extracted as the patent documents including the reference keyword.

In addition, the visualization unit 34 displays only one keyword on the screen if the keywords are the same or similar. For example, only one "motor" keyword is displayed on the screen, and "motor" and "motor" keywords selected by similar keywords are not displayed. In addition, as described above, when the representative keyword by the keyword similar group is used, only the representative keyword is displayed.

Accordingly, if two or more patent documents displayed as nodes on the screen include all one keyword, intuitively know that the patent documents are indirectly connected to the edge through the keyword. In particular, patent documents including only one of the keywords belonging to the similar group are linked to the representative keyword and the edge.

The invention made by the present inventors has been described concretely with reference to the embodiments. However, it is needless to say that the present invention is not limited to the embodiments, and that various changes can be made without departing from the gist of the present invention.
