Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a patent analysis system for analyzing the value of a patent held by a company and a patent analysis graph manufacturing method for manufacturing a patent analysis graph showing an analysis result by the patent analysis system.
[0002]
[Prior art]
Conventionally, the number of patents is often used as an index of technical capability, and the formulation of increasing technical capability, that is, increasing the number of patents, has been performed. As a result, the number of patents held by companies has been increasing steadily, and the patent-related budget has increased. In other words, with the increase in the number of patents held, the maintenance pension paid to maintain the patent and its management costs increased, and the patent-related budget was enlarged.
[0003]
In view of this, mainly in the research and development department, etc., examinations are made as to whether or not individual patents need to be maintained. If it is determined that the patent is unnecessary, it is attempted to reduce patent-related costs by organizing patents by stopping payment of maintenance pensions or waiving rights.
[0004]
[Problems to be solved by the invention]
By the way, when the research and development department or the like determines whether or not the patent is unnecessary, it is difficult to determine that the patent is actually unnecessary. That is, even if it is not currently used, it is often not determined that it is an unnecessary patent as a result in consideration of possible future use. Therefore, as a result, the actual situation is that the maintenance pension and administrative expenses are not reduced.
[0005]
In such a case, if you analyze the value of the patents you have and classify each patent into a predetermined category based on its value, you do not need to refer to it when making a judgment on each patent. It is easy to determine whether the patent is a valid patent.
[0006]
An object of the present invention is to provide a patent analysis system for classifying a patent held by a company into a predetermined category based on the value of the patent, and a patent analysis graph manufacturing method for manufacturing a patent analysis graph indicating an analysis result by the patent analysis system Is to provide.

DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, a patent analysis system according to an embodiment of the present invention will be described with reference to the drawings. In the following, the patents held (analyzed patents) are classified as having a high prior application and occupancy, a classification with a high prior application but a low occupancy, a classification with a low prior application but a high occupancy and a prior application. The case of classifying into the four categories of the categories with low sex and occupation ratio will be described.
[0025]
The patent analysis system according to this embodiment includes a data processing unit 2 that performs processing for classifying an analysis target patent based on a reference patent, and the like, and the data processing unit 2 inputs a patent number and the like of the analysis target patent And an output unit 6 for outputting the classification result of the analysis target patent and the like.
[0026]
Here, the analysis target patent is a patent for which it is determined whether or not to continue paying the maintenance pension, and the value of which is to be analyzed. This analysis target patent can be arbitrarily designated by the company itself from among the patents owned by the company. The similar patent is a patent relating to an invention that is technically similar to the analysis target patent. Note that the “analytical patent” and “similar patent” used in this embodiment include not only those after patent but also those pending.
[0027]
Further, the data processing unit 2 includes a patent database 8 storing patent data including a publication gazette, a patent publication gazette, and a utility model gazette, and a dictionary vector storing a dictionary vector used when searching for similar patents. A data storage unit 12 is connected to store the database 10 and the classifications assigned to the patents to be analyzed.
[0028]
The patent database 8 stores data relating to patents published by the Japan Patent Office and data relating to patents published by institutions corresponding to the patent offices in other countries. The patent database 8 also stores data such as the patent number, filing date, applicant, inventor, specification and abstract of the analysis target patent, that is, analysis target patent data.
[0029]
The dictionary vector stored in the dictionary vector database 10 is a vector defined in a patent-specific dictionary space of several hundred dimensions. For example, based on a publication for the past year, similar words (identical This is a vector created by giving a vector having a direction similar to that of words appearing in the publication. That is, the direction of the dictionary vector is a vector representing the contents of the publication.
[0030]
Next, the analysis target patent classification process will be described with reference to the flowchart of FIG. In the following, a case will be described as an example in which company A analyzes patents in order to organize its own patents.
[0031]
First, the analysis target patent data is acquired by inputting the patent number of the analysis target patent through the input unit 4 configured by a keyboard or the like (step S10). That is, patent data corresponding to the inputted patent number, for example, the filing date, the applicant, the scope of claims, and the like are extracted from the patent database 8 as analysis target patent data. The extracted analysis target patent data is stored in the data storage unit 12 in association with the patent number. In addition, when there are a plurality of analysis target patents, the patent data of the corresponding patent numbers are extracted from the patent database 8 by inputting the patent numbers of the respective analysis target patents via the input unit 4. The number is stored in the data storage unit 12 in association with the number. Note that by inputting an application number or a publication number, an analysis target patent may be specified and analysis patent data may be acquired. Further, a list of application numbers or publication numbers may be displayed, and the analysis patent data may be acquired by specifying the analysis target patent from the application number or publication number.
[0032]
Alternatively, the inventor, the international patent classification (IPC) or the applicant may be input via the input unit 4 to obtain the analysis target patent data. For example, by inputting A company as a specific IPC and applicant, a patent in the specific technical field of A company may be used as an analysis target patent, and the analysis target patent data may be acquired from the patent database 8. The patent data to be extracted as the analysis target patent data can be arbitrarily designated such as the filing date, the applicant, the claims and the summary, or all the data related to the analysis target patent. Here, the scope of claims may be limited to claim 1 only.
[0033]
Next, an item for searching for a similar patent similar to the analysis target patent by concept search, that is, an item to be a concept search target is designated (step S11). For example, whether the concept search is performed for all the claims of the patent to be analyzed, the concept search is performed for a part of the claims (for example, only claim 1), or the entire specification is Specify whether to perform concept search as a target.
[0034]
Next, based on the search item specified in step S11, a similar patent similar to the analysis target patent is searched from the patent data stored in the patent database 8 by a concept search (step S12). When there are a plurality of analysis target patent data, similar patents for each analysis target patent are searched by concept search.
[0035]
Here, the concept search will be described by taking as an example a case where a claim is designated as a search item. First, based on the dictionary vector stored in the dictionary vector database 10, a document vector representing the contents described in the claims of each patent is created for each patent stored in the patent database 8. That is, when patent data of 10,000 patents is stored in the patent database 8, a document vector is created for each of the 10,000 patents. Next, based on the dictionary vector stored in the dictionary vector database 10, a search vector that represents the contents described in the claims of the patent to be analyzed is determined.
[0036]
Then, inner product values of the search vector and the document vector created for each patent are calculated, and extracted as similar patents in descending order of inner product values. For example, if 10,000 patent document vectors have been created, inner product values of the search vector and each of the 10,000 document vectors are calculated and extracted in descending order of inner product values.
[0037]
Next, a predetermined number of reference patents are selected in descending order of similarity among the extracted similar patents (step S13). FIG. 3 is an example of a list of reference patents in which 15 cases are extracted in descending order of the inner product value. As shown in FIG. 3, the reference patent is shown in a list format in which the inner product value of the document vector and the search vector, the patent number, the filing date, the first IPC, the title of the invention, and the applicant's items are described. Further, the patent (patent number 2811222) having an inner product value of 100 is not a similar patent but an analysis target patent. That is, since the patent data of the patent 2811222 is also stored in the patent database 8, a document vector is created for the patent 2811222, and the inner product value of the created document vector and the search vector is calculated. In this case, since the document vector and the search vector are the same vector, the inner product value is 100, and the similar patent having the highest similarity is searched.
[0038]
Further, when there are a plurality of analysis target patents, similar patents are searched by concept search for each analysis target patent, and a plurality of lists indicating reference patents as shown in FIG. 3 are created for each analysis target patent. The
[0039]
  Next, among the reference patents searched in step S13, a reference patent that is a prior application to the analysis target patent is extracted (step S14). For example, among the 15 reference patents shown in FIG. 3, the reference patents of the prior application are extracted from the analysis target patent 2811222, and the number is counted. Here, the prior-application property of the analysis target patent is high when there are fewer reference patents of the prior application than the analysis target patent, and is low when there are more reference patents of the prior application than the analysis target patent. When there is a reference patent having the same filing date as the analysis target patent, the reference patent may be excluded at the time of aggregation. In addition, the number of reference patents with the same filing date is equal to the number of prior applications of other reference patents.Later applicationYou may make it distribute proportionally to the ratio with the number of.
[0040]
Next, a reference patent of the same applicant as the analysis target patent is extracted from the reference patent (step S15). For example, among the 15 reference patents shown in FIG. 3, the same reference patent as that of the analysis subject patent 2811222 is extracted, and the number is counted. Here, the occupation ratio of the patents to be analyzed is high when the applicant has many reference patents with the same applicant, and is low when the applicant has few reference patents with the same applicant.
[0041]
Next, the position of the analysis target patent, that is, the position of the analysis target patent on the table shown in FIG. 4 is determined based on the number of reference patents of the prior application and the number of reference patents of the same applicant (step S16). FIG. 4 is a table in which the prior application based on the number of reference patents of the prior application is plotted on the vertical axis, and the occupancy ratio based on the number of reference patents by the same applicant is plotted on the horizontal axis. In this case, the positions of all the patents to be analyzed on the table are determined.
[0042]
Next, when the positions on the table shown in FIG. 4 are determined for all the patents to be analyzed (step S17), the prior application is divided into two at a predetermined position and the occupation ratio is 2 at a predetermined position. The four sections are determined by dividing them into two (step S18).
[0043]
At this time, the category of the patent to be analyzed is determined depending on where in the four categories the patent to be analyzed belongs. The determined classification of the analysis target patent is stored in the data storage unit 12 in association with the patent number for each analysis target patent. In this embodiment, the ranges of the four sections are determined by using the intermediate points on the vertical and horizontal axes as the boundary lines of the sections.
[0044]
Here, the classifications of the patents to be analyzed are the four categories of the preceding monopoly, the leading rifle, the late pinpoint, and the late neighborhood as shown in FIG. Analytical patents classified in the category of prior monopoly are patents with high prior application and occupancy rates, while patents to be analyzed classified in the preceding rifle category are patents with high prior application but low occupancy rates. is there. Analytical patents classified in the later pinpoint category are patents with low prior application and low occupancy rates. Analytical patents categorized in the later peripheral category are low in prior application but have low occupancy rates. It is a high patent.
[0045]
The patents subject to analysis classified in the category of prior monopoly are patents that have been filed in advance of other companies, and that have been solidified as peripheral patents. The patents to be analyzed that are classified in the preceding rifle category are patents that have been filed earlier than other companies, but have more rival patents around them. Also, the patents to be analyzed that are classified into the category of the later pinpoints are patents that should be actively organized because there are many patents of other companies that have preceded the application. Furthermore, the analysis-targeted patent classified into the category of the peripheral area of the later generation is a patent application that is a late-generation application, but has a large number of in-house patents, and its validity needs to be confirmed.
[0046]
Next, the number of analysis target patents is tabulated for each category into which the analysis target patents are classified (step S19). That is, when all the analysis target patents are classified into the predetermined categories, the respective analysis target patent categories are stored in the data storage unit 12 in correspondence with the patent numbers of the analysis target patents as shown in FIG. The Then, based on the classification of each analysis target patent stored in the data storage unit 12, the number of analysis target patents is totaled for each classification. That is, the number of patents to be analyzed classified into the preceding monopoly classification, the preceding rifle classification, the subsequent pinpoint classification, and the subsequent peripheral classification is aggregated for each classification.
[0047]
Next, the totaled results are output via the output unit 6 (step S20). That is, the results tabulated in step S19 are graphed and output via the output unit 6 constituted by a printer or CRT. Therefore, it is possible to produce a graph that can be used as a reference for making a clear decision regarding patent arrangement or the like.
[0048]
FIG. 7 shows an example in which the tabulation results are graphed. As shown in FIG. 7, the analysis-target patents classified into the preceding monopoly section, the preceding rifle section, the subsequent pinpoint section, and the subsequent peripheral section are graphed. As a result, it is possible to visually recognize the status of patents owned by a company in an easy-to-understand manner and easily grasp the status of patent arrangements.
[0049]
In addition, by classifying the analysis target patent into a predetermined category before a predetermined period, such as the due date for payment of the maintenance pension of the patent, it should be an accurate reference material for determining whether or not to hold the analysis target patent. Can do. In other words, the analysis-target patents classified in the preceding monopoly category are important patents having a large utility value, and therefore the patents classified in this category can be excluded from the objects to be organized. Further, it is possible to determine whether or not the analysis target patent classified into the preceding rifle category is a patent to be arranged by examining whether or not the patent is desired by another company. In addition, since the analysis target patents classified in the later pinpoint category are low-value patents, it can be determined that they should be actively organized. And it is possible to determine whether or not a patent classified in the category around the latecomer is a patent to be arranged by considering the importance of the product in-house. Note that how to determine the patents classified in each category can be determined as appropriate based on business development, intellectual property strategy, and the like for each company.
[0050]
In addition to patents, by classifying a patent application into a predetermined category before the deadline for requesting examination of an application, it can be used as a reference when deciding whether to request application examination for that patent application. it can. As a result, it is possible to reduce unnecessary application examination request fees and efficiently reduce patent-related costs by not making an application examination request for a patent application that is unlikely to be entitled.
[0051]
According to the patent analysis system of this embodiment, the patents held are classified into predetermined categories based on the viewpoints of prior application and occupation ratio. Therefore, when organizing patents held, it is possible to clarify patents that should be preferentially sorted according to which category the patent is classified, and to quickly sort patents. At the same time, it is possible to clarify the patents that can be excluded from the object of organizing and organize the patents held properly.
[0052]
Also, unlike narrowing down some important patents from all owned patents, the scope is classified as a patent that is likely to be an important patent or a patent that is unlikely to be an important patent. Since it is possible to determine whether or not it is a necessary patent, it is easy to determine whether or not a possessed patent is necessary, and unnecessary patents can be efficiently organized. And, for example, by promoting the organization of unnecessary patents that are approaching the maintenance pension payment deadline (next patent payment deadline), the expenses necessary to avoid unnecessary maintenance pension payments and maintain patents held Can be efficiently compressed.
[0053]
In addition, by classifying a patent application into a predetermined category when the application examination request deadline is approaching, the patent application is evaluated and used as a reference in determining whether an application examination request is necessary. By not filing an application examination request for unnecessary patent applications, unnecessary patent-related costs can be efficiently compressed.
[0054]
In addition, by graphing and outputting the results of classifying the analysis target patents into predetermined categories, it is possible to visually recognize what kind of patent the company owns is easy to understand. In addition, by recognizing the patents owned by the company in an easy-to-understand manner, it is possible to easily grasp whether the patents held are properly organized or insufficiently organized. Can do.
[0055]
In the above-described embodiment, similar patents by the same applicant as the analysis target patent are extracted. However, when the subsidiary is the applicant, the share of the analysis target patent is determined as the same applicant. You may make it do.
[0056]
Further, in the above-described embodiment, a predetermined division into which the analysis target patent is classified is determined by dividing the table showing the position of the analysis target patent into four almost evenly. The scope of the classification may be changed based on the business development or intellectual property strategy. That is, the boundary line of the classification based on the prior application property may be changed, or the boundary line of the classification based on the occupation ratio may be changed.
[0057]
In the above-described embodiment, the analysis target patents are classified into four categories based on the prior application and the occupancy ratio, but it is divided into six based on the business development and intellectual property strategy for each company. , It may be divided into 9 parts. That is, the number of divisions may be arbitrarily changed by increasing the number of axes that are the boundary of the division based on the prior application or the number of axes that are the boundary of the division based on the occupation ratio. .
[0058]
Further, in the above-described embodiment, a table in which the prior application of the analysis target patent is based on the predetermined number of reference patents selected in descending order of similarity from the similar patents, and the occupation ratio is the horizontal axis. Although the above position is determined, the position of the analysis target patent may be determined based on a reference patent having an inner product value equal to or larger than a predetermined value from similar patents.
[0059]
Further, in the above-described embodiment, the reference patent that is the prior application is extracted based on the filing date, but the reference patent that is the prior application is extracted using the priority date instead of the filing date. Then, the prior application property of the analysis target patent may be determined by counting the number.
[0060]
  In addition, the patent data stored in the patent database is updated every night for a predetermined period, for example, every night or every time a bulletin is issued.right beforeYou may make it classify | categorize an analysis object patent into a predetermined classification based on the updated patent data. That is, the process of classifying the analysis target patent may be performed based on the latest patent data published at that time.
[0061]
In addition, by comparing the patent analysis result by this patent analysis system with the patent analysis result of another company, it is possible to clarify the difference between the intellectual property strategies of the company and the other company. In addition, by comparing the analysis results of our company and other companies in the same technical field, it is possible to clearly know which of the two is dominant in the technical field.
[0062]
【The invention's effect】
According to the patent analysis system of the present invention, when examining whether or not to continue paying the maintenance pension, etc., the priority order of the examination is determined by referring to which category the patent to be analyzed is classified. Can be determined. In addition, it can be used as an accurate reference material for determining whether or not to continue to pay maintenance pension depending on which category it is classified into. Therefore, the analysis patents that are classified into categories that indicate a low need to pay maintenance pensions are preferentially examined, and judgments are made by referring to the classification as such categories. It becomes easy. As a result, it is possible to properly organize patents and efficiently reduce patent-related costs.
[0063]
In addition, companies that have a large number of patents can easily determine which patents should be preferentially sorted or patents that need not be sorted because the patents to be analyzed are categorized into predetermined categories. be able to. Therefore, it is possible to reduce the labor required for organizing patents and efficiently reduce patent-related costs.
[0064]
According to the patent analysis graph manufacturing method of the present invention, it is possible to manufacture a graph that can be used as a reference for accurately performing judgments such as organizing patents.
