In this way, since the appearance and appearance of the warrior 220 changes according to the level, it is possible to increase the willingness to create inventions.

FIG. 6 is a flow chart showing an operation example of the patent map display device 1 according to the first embodiment of the present invention.

A plurality of preceding patent information are stored in the document database 20, and as shown in FIG. 6, the user inputs instruction information representing an evaluation target in the input field of the user terminal 100 (S1). The instruction information is information indicating the content of the technology to be evaluated, and is information including a keyword with which the technical content can be specified. The user can input not only the technical content representing the object of evaluation, but also the technical classification such as the International Patent Classification IPC or time information such as the application date. When instruction information is entered in the input field of the user terminal 100, the patent map display device 1 acquires the instruction information. The information acquisition unit 10 acquires the instruction information.

Subsequently, based on the obtained instruction information, the analysis unit 30 analyzes the instruction information representing the evaluation target obtained in S1 (S2).

Specifically, the comparison unit 31 provided in the analysis unit 30 compares the instruction information representing the evaluation target acquired in S1 and the preceding plural pieces of patent information stored in the document database 20 . By comparing the instruction information and the patent information, the judgment as to whether or not the technical contents of the plural pieces of patent information and the instruction information are similar can be made, for example, by the International Patent Classification (IPC) assigned to the patent information. It is determined by the degree of matching between Note that the degree of coincidence is not limited to the international patent classification IPC, and may be determined by FI (File Index), F-term, CPC (Cooperative Patent Classification), or the like.

In addition, the judgment as to whether or not the technical contents of the multiple pieces of patent information and the instruction information are similar is based on the technical wording included in the instruction information representing the evaluation target and the multiple pieces of patent information stored in the document database 20. Relevance may be made by comparison. A technical phrase is a sentence, a combination of phrases, a phrase, or a word contained in technical information. Further, the judgment may be made by the comparison unit 31, and whether or not the sentences are similar may be judged by comparing the distance between the sentences included in the instruction information and the preceding plural pieces of patent information.

Subsequently, the evaluation unit 32 evaluates the instruction information based on the comparison result. Evaluation is performed by inputting the comparison result to the evaluation unit 32 .

By evaluating in this way, evaluation closer to the actual examination results can be made possible. That is, it is possible to compare and evaluate patent information including technical wordings indicating the same meaning, although different wordings, with respect to instruction information representing an object of evaluation, thereby enabling evaluation closer to actual examination results.

Subsequently, the generation unit 41 generates the battlefield map 210 and the warrior 220 representing the attribute of the instruction information based on the attribute information including the patent evaluation analyzed in S2 (S3). A plurality of types of battlefield maps 210 and warriors 220 are stored in the storage unit 60 in relation to attribute information, and battlefield maps 210 and warriors 220 that match the attribute information can be generated.

Specifically, each piece of attribute information is associated with a plurality of types of battlefield maps and warriors. A battlefield map 210 and warriors 220 representing attributes are generated for the analysis results obtained.

Subsequently, the placement unit 42 creates the patent map 200 by placing the warriors 220 created in S3 on the battlefield map 210 (S4). Note that the placement unit 42 may change the placement relationship of the warriors 220 according to the degree of coincidence and similarity of the technical content of the instruction information and the preceding patent information. For example, if the instruction information and the patent information have similar technical contents, the warriors may be arranged adjacent to each other.

By arranging the warriors next to each other in this way, groups of similar technical fields can be grasped at a glance. It is possible to immediately visually recognize the technological trend of a specific company. In addition, it is possible to easily recognize the application trends of your company or specific companies from such technological trends, and instantly grasp comprehensive technological trends including the strengths and weaknesses of each company's technology and technological blank areas. It can be used effectively for corporate management strategy and business strategy.

According to the flow described above, the patent map 200 generated in S4 is displayed in the input field of the user terminal 100 (S5). The display of the patent map 200 is performed by the display unit 50 . For example, when the display unit 50 issues an output instruction to the patent map generation unit 40, the image of the patent map 200 is output and displayed on the user terminal 100. FIG.

FIG. 7 is a diagram showing an example of a mode in which a band-shaped information bar 300 is displayed on the patent map 200. As shown in FIG. The generation unit 41 has a function of generating an information bar 300 representing a time axis showing changes in time. As shown in FIG. 7, as time passes, warriors 220 are placed on map 210, and information bar 300 is displayed in the direction of time (the direction of the arrow from 2000 to 2020 in FIG. 7). It may be configured to be arranged along. The arrangement is performed by the arrangement section 42 . The information bar 300 refers to a time axis showing changes in time. The patent map 200 ′ generated by the above arrangement is displayed on the user terminal 100 . The display on the user terminal 100 is performed by the display unit 50 .

In this way, the warrior 220 and the information bar 300 are arranged on the battlefield map 210 along the direction of the passage of time, so that the user can easily grasp the history (trend) of the idea created in the past. can do. The patent map 200′ generated (created) in this way is stored in the storage unit 60, and the user can view the patent map 200′ at any time, which shows the chronological trends (trends) of the creation time of his/her idea. can do. Ideas include published patents, unpublished patents, and unfiled patents (including pending inventions, abandoned inventions, and know-how).

This makes it possible to visually confirm application trends, technology trends, etc., of one's own technology, and clearly grasp areas where the protection of one's own technology is sufficient and areas where protection is insufficient. Therefore, it is possible to identify fields in which inventions should be created in the future and patent protection should be strengthened, and to predict future applications.

Furthermore, an information bar 300 along the time axis showing changes in time can be displayed on the patent map 200' based on the analysis results of not only the technology of the company but also the technology of other companies. As a result, it is possible to recognize application trends, technology trends, etc. that match the times in chronological order. It is possible to grasp Therefore, the patent map 200' can be effectively utilized for corporate management strategy and business strategy.

Further, according to this embodiment, the technical field and evaluation (strength of the invention) can be recognized at a glance from the topography of the battlefield map 210 and the appearance of the warrior 220, for example, the color of the warrior's clothing, the weapons he/she has, the age, and the like. can do. Therefore, it is possible to easily comprehend application trends, technology trends, etc. in chronological order. According to the patent map display device 1, it is also possible for the user to estimate future filing trends.

Furthermore, as shown in FIG. 8A, it is also possible to show the trend of the company's technology as a bird's-eye view 230 . The horizontal axis shows the affinity of the company's technology, and the vertical axis shows the marketability. Promising business areas can be recognized at a glance.

Also, as shown in FIG. 8B, the core technology of the company and the peripheral technologies of other companies can be shown as a chart 240 . This makes it possible to estimate future candidate business areas.

According to this embodiment, the patent map 200 , the bird's-eye view 230 , and the chart 240 can be arbitrarily switched and displayed on the user terminal 100 . The switching is performed by a switching unit (not shown) included in the patent map display device 1, for example.

In addition, according to the patent map display device 1 according to the present embodiment, the warrior 220 can move on the battlefield map 210 . The movement is performed by, for example, a control unit (not shown) included in the patent map display device 1 . The controller may change the distance traveled by the warrior 220 according to the patent evaluation based on the analysis results. For example, in moving, the degree of similarity between the technical content to be evaluated and the multiple pieces of patent information is determined according to the degree of matching between the technical content to be evaluated and the multiple pieces of patent information. A control unit (not shown) may control the warrior 220 to be able to move over a wide area on the map 210 when the degree of similarity is high. Also, the controller (not shown) may control the warrior 220 to move only in a narrow area on the map 210 when the degree of similarity is low. A control unit (not shown) controls the warrior 220 to move freely within the movement area. The degree of similarity may be determined based on the number of characters in claims. The number of characters in claims is calculated by, for example, a counting unit (not shown) provided in the patent map display device 1 . For example, if applicants are different, adjacent warriors 220 may fight each other, or warriors may fight each other if they encounter other warriors while moving. Applicants holding highly rated patents can be easily identified. A control unit (not shown) has the function of allowing the warrior 220 to move within the movement area. For example, a controller (not shown) can control the warrior 220 to autonomously move according to a preset movement area corresponding to the patent evaluation. The storage unit 60 can store a plurality of types of moving regions corresponding to patent evaluations. Warrior 220 can be controlled to move autonomously according to a preset movement area based on not only patent evaluation but also level and rank.

Next, a modified example of this embodiment will be described with reference to FIGS. 9 to 12. FIG. FIG. 9 is a diagram showing an example of a patent map output to a user terminal according to a modification of one embodiment of the present invention. Moreover, FIG. 10 is a schematic diagram explaining the cross section of the aspect of a patent map. Also, FIG. 11 is a flow chart showing an example of the display operation of the patent map display device 1 according to the modification of the embodiment. 12 is a partially enlarged view showing an example of the A portion of FIG. 9. As shown in FIG. It should be noted that the description and description of the configuration similar to the embodiment described with reference to FIGS. 1 to 8 will be omitted in order to avoid redundant description of the drawings.

Information including instruction information and patent information is hereinafter referred to as "technical information" as appropriate.

The "technical information" includes instruction information as information indicating the content of the technology (invention) to be evaluated, and patent information as information for determining the possibility of obtaining patent rights. The “technical information” may include patent information researched by the user in the past, and non-patent documents such as research papers, books, and magazines.

According to the patent map display device 1 according to the present modification, the comparing section 31 can compare the technical information including the instruction information and the preceding patent information, and determine the degree of similarity of arbitrary technical information. Then, the placement unit 42 can place the character 220 representing the technical information on the map 210 as display data for displaying the character 220 on the map 210 according to the degree of similarity. For example, the arranging unit 42 uses display data for displaying on the map 210 a character 220 representing a plurality of pieces of instruction information as information indicating the content of the technology (invention) to be evaluated input to the user terminal 100. , may be arranged on the map 210 according to similarity. This makes it possible to visually recognize the technological trends of one's own company easily.

In addition, the arrangement unit 42 arranges the character 220 representing the preceding patent information as information for determining the possibility of acquiring the right of the instruction information as display data for displaying on the map 210 according to the degree of similarity. 210. This makes it possible to visually recognize technical trends of other companies other than one's own company.

Further, the arranging unit 42 may arrange the character 220 representing the instruction information and the preceding patent information on the map 210 as display data for displaying the character 220 on the map 210 according to the degree of similarity. As a result, it is possible to easily visually recognize the technological level and technological trends of competitors (other companies) of one's own company. Note that the arrangement unit 42 also maps the character 220 according to the degree of similarity in the same manner as described above, regarding patent information researched by the user in the past, and technical information related to non-patent documents such as research papers, books, and magazines. 210.

Judgment (judgment) as to whether or not the technical content of one technical information is similar to the technical content of another technical information is, for example, by comparing words (keywords, idioms, etc.) included in the text of the technical information. You can judge by doing. This determination is made by the comparison unit 31 . The comparison unit 31 compares words with a high appearance frequency among a plurality of words included in one technical information and other technical information, and compares the one technical information with the other technical information according to the degree of matching. may be determined. The patent map generator 40 outputs words with a high degree of matching on the map 210 . When the degree of matching of words with high frequency of appearance is high, for example, when the degree of matching of words with the highest frequency of appearance is 80% or more, the comparison unit 31 determines the degree of similarity between one piece of technical information and another piece of technical information. can be judged to be high. Then, the arrangement unit 42 may densely arrange the characters 220 having a high degree of word similarity at close positions. Then, the display unit 50 may display, for example, an icon of a castle-shaped image in the densely populated area. As a result, it is possible to visually recognize a predetermined area containing technical information in which characters 220 with a high degree of similarity are densely packed, and to easily grasp the area of technical information to which attention should be paid.

Alternatively, the placement unit 42 may place the word in the vicinity of the character 220 placed on the map 210 and the display unit 50 may output the word in the vicinity. The frequency of occurrence of words is tallied by a tally unit (not shown). Note that if there are words with a high degree of similarity among the plurality of words output on the map 210, the words may be connected by a line L. FIG. According to the patent map display device 1 according to the modified example, there is a possibility that technical information in which a word with a high appearance frequency matches with a high degree of coincidence and technical information in which a word similar to the word in question has a high appearance frequency are highly similar to each other. Therefore, by connecting words with a line L, it is possible to easily grasp a set of technical information with a high degree of similarity.

Also, the comparison unit 31 determines whether the technical content of one piece of technical information is similar to the technical content of another piece of technical information based on whether the technical classification including the international patent classification IPC assigned to the patent information matches. You may judge by degree and similarity. The degree of coincidence and degree of similarity of the technical classification including the international patent classification IPC is determined by, for example, whether or not the technical classification matches for a predetermined number of digits from the beginning. This determination is made by the comparison unit 31 . The technical classification may be determined based on attribute information based on the result of analysis processing by the analysis unit 30. FIG. This determination is made by the generator 41 . Then, the arranging unit 42 may densely arrange the characters 220 having a high degree of similarity in technology classification at close positions. Also, the placement unit 42 may place the technology classification in the vicinity of the character 220 placed on the map 210 and output it in the vicinity by the display unit 50 . Technical classifications with high similarity terms are tallied by a tally unit (not shown).

Note that the comparison unit 31 may determine whether or not the technical content of one technical information is similar to the technical content of another technical information based on a combination of words and technical information. As a result, according to the patent map display device 1 according to this modified example, it is possible to realize highly accurate similarity determination and to provide a patent map that enables a high level of understanding of technical trends of companies. become.

Then, as shown in FIGS. 9 and 10, the generator 41 can change the topography of the map 210 according to the number of pieces of similar technical information. Specifically, when the number of similar technical information is equal to or less than the first threshold, the generation unit 41 can generate a concave topography of the map 210 in a predetermined area in which the character 220 representing the technical information is arranged. can. More specifically, as shown in FIG. 10, when the number of similar technical information is small (for example, 5 or less), the generation unit 41 creates a predetermined The terrain of the area may be generated in a valley shape (see part N in FIG. 10). A tally unit (not shown) tallies the number of cases. As shown in FIG. 10, the display unit 50 displays the height of the peak (see M in FIG. 10) and the depth of the valley (see N in FIG. 10) according to the number of similar technical information. The terrain of map 210 may be displayed and output as it changes. Moreover, the display unit 50 may change the degree of inclination of the slope connecting the peak and the valley according to the degree of similarity of the technical information.

The storage unit 60 stores a plurality of types of terrain information associated with the character 210 placed on the map 210, and according to the number of pieces of technical information as the character 210 placed on the map 210, the degree of similarity, etc., It is read out from the storage unit 60 . Then, the map 210 read from the storage unit 60 may be associated with the character 210 and displayed on the user terminal 100 by the display unit 50 .

Further, based on the terrain information stored in the storage unit 60, the calculation process may be changed according to the character 210 placed on the map 210. FIG. This calculation is performed by, for example, a calculator (not shown). The storage unit 60 stores the coordinate data of the height of the mountain and the coordinate data of the depth of the valley in association with the number of pieces of technical information as the character 210 placed on the map 210 and the degree of similarity. Specifically, the coordinate data of the height of the mountain and the coordinate data of the depth of the valley are calculated by a calculation unit (not shown) that is changed according to the number of pieces of technical information as the character 210 and the degree of similarity. Processing is performed and stored in the storage unit 60 . The generation unit 40 may be configured to read these coordinate data from the storage unit 60 and convert them into an image as terrain information to generate the map 210 . For example, the generation unit 40 is configured to generate three-dimensional terrain information as an image based on the coordinate data of the height of the mountain and the coordinate data of the depth of the valley.

Further, when the number of pieces of similar technical information is equal to or greater than the second threshold, the generation unit 41 may generate a convex landform of the map 210 in a predetermined area in which the character 220 representing the technical information is arranged. More specifically, as shown in FIG. 10, when the number of similar technical information is large (for example, 20 or more), the generation unit 41 creates a predetermined The landform of the area may be generated in a mountain shape (see part M in FIG. 10). The comparison unit 31 determines whether the number of similar technical information is equal to or greater than a predetermined threshold or equal to or less than a predetermined threshold.

Furthermore, the display unit 50 can display and output the landform by displaying the landform of a mountain generated in a convex shape in a dark color and by displaying the landform of a valley formed in a concave shape in a light color. The storage unit 60 may store a plurality of types of landform information with varying shades according to the undulating shape of the unevenness in association with the number of characters 210 placed on the map 220 . Alternatively, the generation unit 41 quantifies the color tone so that, for example, the gradation changes from the convex shape to the concave shape as the ground becomes low, and the brightness and chromaticity are calculated for each height difference between the convex shape and the concave shape. , may be configured to generate three-dimensional terrain information as an image by assigning luminance. Alternatively, the storage unit 60 may associate the coordinate data of the convex shape and the concave shape with the gradation data of the terrain information for each height difference of the terrain. Then, the generating unit 41 assigns the coordinate data and the gradation data of the terrain stored in the storage unit 60 according to the arrangement of the character 210 on the map 220 as the technical information, thereby converting the three-dimensional terrain information into an image. may be configured to generate as

According to the patent map display device 1 according to this modified example, the topography of the map 210 can be visually recognized at a glance according to the number of similar technical information. can be grasped.

In addition, the arranging unit 42 can arrange the characters 220 representing technical information with a high degree of similarity at positions close to each other, and the characters 220 representing technical information with a low degree of similarity at positions distant from each other. Specifically, when the character 220 representing the technical information is set as a base point, the arranging unit 42 arranges the character representing the technical information having a high degree of similarity with the character 220 according to the degree of similarity. can be done. The user can specify any one piece of technical information as a base point via the user terminal 100, and the information acquisition unit 10 acquires the base point. More specifically, the arranging unit 42 can arrange the characters in positions close to each other for technical information having a high degree of similarity with any one piece of technical information. On the other hand, the arranging unit 42 can arrange the characters at positions distant from each other for technical information having a low degree of similarity with any one piece of technical information. By calculating the degree of similarity as a score, the placement calculates the distance from any one piece of technical information as a relative evaluation of any one character 220 (for example, the evaluation target character 220) arranged on the map 210. You may This calculation is performed by a calculator (not shown). Note that the score and the distance are associated with each other, and the distance may be calculated as an absolute evaluation with any one piece of technical information. The correspondence between scores and distances is stored in the storage unit 60 . The matching score can be calculated, for example, as a numerical value from "0%" to "100%" according to the degree of matching. Further, the calculation unit (not shown) may calculate the distance from any one character 220 for all the characters 220 placed on the map 210, or may The distance may be calculated for each predetermined area on the map 210 where the 220 is arranged.

Furthermore, the generation unit 41 can generate additional information with improved possibility of obtaining the right according to the possibility of obtaining the right related to the user's instruction information. The possibility of rights acquisition is determined according to the degree of similarity. Specifically, the comparison unit 31 compares the user's instruction information with sentences included in a plurality of preceding patent information, and calculates the degree of similarity according to the degree of matching. Then, if there is technical information having a high degree of similarity with any one of the instruction information of the user to be evaluated among the plurality of pieces of technical information, the generation unit 41 determines that the possibility of obtaining the right is low. This determination is made by the evaluation unit 32 . In this case, the generation unit 41 can propose information to be added, corrected, or deleted from the instruction information to the user as additional information in order to improve the possibility of obtaining the right. The additional information can be generated by AI (Artificial Intelligence).

When the evaluation unit 32 determines that the possibility of obtaining the right is low, the generation unit 41 generates additional information that increases the possibility of obtaining the right by supplementing and correcting any one of the technical information to be evaluated. can be done. The generation unit 41, for example, learns through machine learning and adds constituent elements (words or sentences) that improve the possibility of obtaining rights in past examinations to the constituent elements of the invention, based on past examinations. Additional information can be generated that improves the likelihood of obtaining rights.

On the other hand, if the evaluation unit 32 determines that the possibility of obtaining the right is high, the generating unit 41 generates information that lowers the possibility of obtaining the right in supplementary correction of any one technical information to be evaluated. may be performed. The generating unit 41 may consider generating information that lowers the possibility of obtaining the right in supplementary correction of any one piece of technical information to be evaluated. For example, supplemental corrections of the technical information may consider generating information that deletes certain elements of the technical information. An amendment that deletes the constituent elements of the content of the invention as any piece of technical information to be evaluated lowers the possibility of obtaining the right, but can expand the scope of the right of the invention. The generation unit 41 can generate information that expands the scope of rights by deleting the constituent elements of the invention. The generation unit 41 generates information for deleting constituent elements that have little effect on the possibility of obtaining the right, thereby expanding the scope of the right of the invention while maintaining the possibility of obtaining the right.

The generation unit 41 may generate additional information based on information recorded in an information recording unit (not shown). The generation unit 41 can use the knowledge of the engineer by referring to the intellectual property created in the past by the engineer recorded in the information recording unit (not shown). Thereby, the generation unit 41 may generate additional information similar to information created by the engineer himself on behalf of the engineer. The generating unit 41 may generate additional information based on information about intellectual property recorded in an information recording unit (not shown) by another engineer (for example, an engineer from the same company). In this modified example, a case has been described in which information for deleting a constituent element is generated as additional information when it is determined that the possibility of obtaining the right is high, but the present invention is not limited to this. The generation unit 41 may be configured to delete some of the words, phrases, sentences, etc. included in the constituent requirements. Even in this case, the generating unit 41 generates information for deleting words, phrases, sentences, etc. that have little effect on the possibility of obtaining the right, as described above, thereby maintaining the possibility of obtaining the right. It is possible to expand the scope of invention rights.

In addition, the generation unit 41 may apply a simulation technique to the created invention to detect defects in the invention and exclude them from the creation target. Simulation technology includes, for example, fluid analysis technology for models modeled by CAD, etc., technology for simulating drug production, technology for calculating cost or time required for implementation, technology for detecting scientific contradictions, etc. can be used.

Furthermore, according to the possibility of acquiring the right related to any one piece of technical information to be evaluated, determined by the evaluation unit 32, the output (extraction) of preceding patent information is performed using a technical classification different from that of the relevant technical information. It can be carried out. Then, the generation unit 41 compares sentences included in the preceding patent information and any one piece of technical information to be evaluated, and forms a difference between the preceding patent information and any piece of technical information. Additional information can be generated based on the document information.

The technical classification of the preceding patent information is determined so as not to duplicate the technical classification of any one of the technical information to be evaluated. In the following description, the technical classification of any one piece of technical information to be evaluated is called the first technical classification, and the technical classification of preceding patent information is called the second technical classification. Note that the technical classification is not limited to the international patent classification IPC, and may be FI (File Index), F-term, CPC (Cooperative Patent Classification), or the like.

A technology classification that is not similar to the first technology classification may be selected as the second technology classification. For example, the selection unit (not shown) can select dissimilar technical classifications by excluding technical classifications (patent classifications such as IPC, FI, etc.) that match a predetermined number of digits from the beginning. That is, if the selection unit (not shown) can designate the second technical classification at a predetermined distance from the first technical classification on the patent classification, the selection method is not limited to the above. Furthermore, it is preferable that the predetermined distance is set to a different value depending on the technical classification. For example, in the technical field of IT software, it is often judged that combinations are fundamentally easy even across technical classifications, so it is necessary to set a large predetermined distance. That is, the predetermined distance can be set as a first predetermined number of digits (eg, 4 digits) from the beginning of the first technical classification and a second predetermined number of digits (eg, 3 digits) from the beginning. Here, the second predetermined number of digits must be smaller than the first predetermined number of digits. With this configuration, the patent map display device 1 excludes patent classifications in which the second technical classification is extremely close to the first technical classification, and searches for preceding patent information contained in the second technical classification that is reasonably close ( extraction).

The second technical classification should have an appropriate distance from the first technical classification. If the distance is too close, patentability may be denied, and if the distance is too far, the technical field may be too different and meaningless. As described above, various methods can be adopted for the method of selecting the second technical classification. For example, the selection unit (not shown) does not match the first predetermined number of digits (for example, 4 digits) from the beginning of the first technical classification, but matches the second predetermined number of digits (for example, 3 digits) from the beginning. You may select a patent class that has a patent as the second technology class.

The display unit 50 can display and output the additional information on the map 210 . For example, on the display unit 50, clicking an icon (button) placed (appearing) near a predetermined area on the map 210 where a character 220 representing arbitrary technical information to be evaluated is placed. may be configured to display and output additional information. Icons are displayed with patterns such as treasure chests, jewels, and hot springs, for example. As a result, according to the patent map display device 1 according to the modified example, it is possible to suggest to the user additional information with a high possibility of acquiring rights in a game-like manner.

Furthermore, the evaluation unit 32 may re-determine the possibility of acquiring rights related to intellectual property including patents based on the additional information generated by the generation unit 41 . By re-determining the possibility of obtaining the right, the generating unit 41 can generate additional information with improved possibility of obtaining the right.

Also, the generation unit 41 can generate a plurality of pieces of additional information. Then, the determination unit (not shown) may re-determine the possibility of obtaining each right based on the plurality of pieces of additional information generated by the generation unit 41 . By re-determining the possibility of obtaining the right related to the plurality of generated intellectual properties, it becomes possible to select the information with the highest possibility of obtaining the right from among the plurality of generated additional information. For example, the generation unit 41 may sort the additional information in descending order of the possibility of obtaining the right in the re-determination result from among the plurality of pieces of additional information, and make a proposal to the user.

In addition, the user can determine which of the instruction information as the content of the invention input via the user terminal 100 and the technical information of other companies has a stronger right. Specifically, the comparison unit 31 compares the instruction information (hereinafter referred to as “technical information A” as appropriate) as the content of the invention input by the user via the user terminal 100 and the technical information of other companies (hereinafter referred to as “technical information A” as appropriate). information B"), the level of strength of rights can be compared. For example, the level of right strength is the score of technical information A and the score of technical information B. The comparison unit 31 can determine that the technical information with a higher score as the level of right strength is a stronger right. Note that the level of right strength is not limited to the score. The level of strength of rights depends on the creation date of the invention, patent application date, remaining duration, number of claim elements, number of claims (number of inventions), patent applications of other inventors, researchers, etc. , and information indicating the invention such as the number of times it has been cited in papers (number of citations). The comparison unit 31 can comprehensively evaluate the information indicating these inventions and determine which information is a strong right.

Also, the comparison unit 31 can compare one or more pieces of technical information A of the user with a plurality of pieces of technical information B of other companies, and determine which piece of information is a strong right. In this case, for example, it can be determined that the technical information with the highest level is the strong right. That is, if the level of the technical information A of the user is the highest, the comparison unit 31 may determine that the own company owns a patent with a stronger right. On the other hand, if the level of one piece of technical information B of another company is the highest, the comparison unit 31 may determine that the other company has a patent with a stronger right.

For example, when the comparison unit 31 determines that the patent is not a strong right (does not have superiority or validity of the right, or is inferior), the display unit 50 displays a predetermined It may be configured to display and output, for example, a long rising smoke (see F part in FIG. 12) for the positions in the area of . In this way, a character 220 as a game-like technical information A within a predetermined area including patents owned by the company and a technical information B within a predetermined area including patents owned by other companies. A character 220 can be made to fight. This allows you to visually recognize which of your company or other companies is superior (whether they have superiority and validity of rights), and which of the patents owned by your company or other companies has stronger rights. You can easily find out what you have.

For example, through the user terminal 100, the user designates one or more pieces of technical information A as characters 220 of his own army, and designates one or more pieces of technical information B with which he wishes to fight as characters 220 of the enemy army. be able to. The information acquisition unit 10 acquires the character as the technical information. When the characters of the own army and the enemy army are specified, the character 220 of the own army moves to the position where the character 220 of the enemy army is. This movement can be performed by a controller (not shown). Then, when the character 220 of the own army moves to the position where the character 220 of the enemy army is located, the screen may be changed to the battle mode screen. This transition is performed by the display unit 50 . Then, the comparison unit 31 compares the technical information A as the characters 220 of the own army with a plurality of pieces of technical information B of other companies as the characters 220 of the enemy army, and determines which information is the stronger right. can be configured to Then, the winning army may be given additional information in the form of points, for example. The display unit 50 displays and outputs icons (buttons) with designs such as treasure chests, jewels, and hot springs near a predetermined area on the map 210 where characters 220 representing the technical information of the victorious army are arranged ( appear).

The additional information generated by the generation unit 41 can be displayed on the screen of the user terminal 100 by the display unit 50 . For example, when the patent map 200 is displayed and output on the user terminal 100, if the match score is low and the possibility of obtaining the right is evaluated as negative (for example, C rank), the generation unit 41 outputs the evaluation result An evaluation signal based on the input may be configured to generate additional information. The display unit 50 may display additional information on the patent map 200 output to the user terminal 100 . For example, when the user hovers over the icon (button), the additional information may be displayed and output together with the light column. It should be noted that if the determining unit (not shown) determines that the possibility of obtaining the right is high, the generating unit 41 generates information that lowers the possibility of obtaining the right in the supplementary correction of the input information. good. The generation unit 41 may also generate information for deleting words, clauses, sentences, etc. that have little influence on the possibility of obtaining the right in the determination unit (not shown).

Further, the patent map display device 1 drags a specific character 210 arranged on the map 220 to display an area such as another technical classification or the like different from the area of the technical classification or words (keywords, etc.) to which the character 210 belongs. can be moved to Then, when it is moved, it is possible to re-determine the possibility of obtaining the right of the technical information related to the character 210 in another technical classification or the like. This re-determination may be performed by a determination unit (not shown). Specifically, if the content of the invention related to the technical information (the input content related to the instruction information, the content of the claim related to the patent information, etc.) is filed for patent in the relevant technical classification, etc., how will it be evaluated? or the possibility of acquiring rights can be re-determined. Then, the generation unit 41 can generate the additional information according to the possibility of obtaining the right. Since the method of generating the additional information has been described above, detailed description thereof will be omitted.

As described above, according to the patent map display device 1, it is possible to generate additional information across technical fields. A difference occurs in the second technical classification at a predetermined distance. Therefore, according to the patent map display device 1, the character 210 can freely move between technical classifications or words (keywords, etc.) on the map 220, and various additional information can be provided to the user. .

Next, an operation example of the patent map display device 1 according to the modified example of the embodiment will be described with reference to FIG. 11 . FIG. 11 is a flow chart showing a display operation example of the patent map display device 1 according to the modification of one embodiment.

<Example of display operation processing of patent map display device 1 according to modification>
In FIG. 11, the comparison unit 31 performs similarity determination of any of the technical information (S11). Specifically, the comparison unit 31 compares the technical information including the instruction information and the preceding patent information, and determines the degree of similarity of arbitrary technical information.

Next, the placement unit 42 places characters 220 representing a plurality of pieces of technical information on the map 210 as display data for displaying them on the map 210 according to the degree of similarity (S12). Specifically, the placement unit 42 sets the character representing the technical information as the warrior 220, and sets the similarity to It can be placed on the battlefield map 210 accordingly. For example, the arranging unit 42 generates display data for displaying a warrior 220 representing a plurality of pieces of instruction information as information indicating the content of the technology (invention) to be evaluated input to the user terminal 100 on the battlefield map 210. , may be arranged on the battlefield map 210 according to the degree of similarity. This makes it possible to visually recognize the technological trends of one's own company easily.

Further, the arranging unit 42 may arrange the warrior 220 representing the preceding patent information on the battlefield map 210 as display data for displaying the warrior 220 on the battlefield map 210 according to the degree of similarity. This makes it possible to visually recognize technical trends of other companies other than one's own company.

Further, the arranging unit 42 may arrange the warrior 220 representing the instruction information and the preceding patent information on the battlefield map 210 as display data for displaying the warrior 220 on the battlefield map 210 according to the degree of similarity. As a result, it is possible to easily visually recognize the technical level and technical trends of the company's competitors. It should be noted that the arrangement unit 42 also uses technical information related to patent information researched by the user in the past and non-patent documents such as research papers, books, and magazines, in the same manner as described above, to place the warrior 220 on the battlefield according to the degree of similarity. It may be placed on the map 210 .

As described above, according to the patent map display device 1, it is possible to visually grasp at a glance the technical fields in which the engineers of each company are actively creating inventions among the wide and diverse technical fields. We can support the construction of intellectual property strategies, development strategies, business strategies, and management capabilities.

Further, according to the patent map display device 1, it is possible to grasp the distribution of technical information for each technical classification on the patent map 200. FIG. When the technology classification is IPC, the patent map generator 40 can generate the distribution status of each piece of technical information belonging to the IPC subclass (A01B in Table 1) as the patent map 200 . Then, the image of the patent map 200 is displayed on the user terminal 100 by the display unit 50 . Also, when hovering over a specific IPC subclass (A01B in Table 1), the patent map shows the distribution status of each technical information belonging to the lower group hierarchy of the subclass (A01B33/00, A01B33/08 in Table 1). 200 can be generated. For example, when generating the patent map 200, the battlefield map 210 and the number of warriors 220, the distribution status are aggregated, and the IPC subclass (A01B in Table 1) and lower group hierarchy (A01B33/00, A01B33 in Table 1 /08) may be associated with the warrior 220 and stored in the storage unit 50 . An aggregation unit (not shown) may aggregate the subclass of IPC, the number of warriors 220 for each hierarchy of the lower group, and the distribution status.

Then, when hovering over a specific IPC subclass (A01B in Table 1), the patent map generation unit 40 generates technical information belonging to the lower group hierarchy of the subclass (A01B33/00, A01B33/08 in Table 1). The distribution of warriors 220 may be generated as a patent map 200. FIG.

In addition, in the patent map display device 1, when a specific IPC subclass is hovered, a battlefield map 220 relating to the hierarchy of the lower group associated with the subclass of the technical classification (IPC) to which the specific warrior 220 belongs is displayed from the storage unit 50. may be read out and the patent map 200 may be output and displayed. Further, in the patent map display device 1, each time a specific IPC subclass is hovered over, a tallying unit (not shown) may tally the number of warriors 220 and the distribution status for each layer of the lower group. Then, the generation unit 41 may be configured to generate three-dimensional terrain information as an image based on the coordinate data of the height of the mountain and the coordinate data of the depth of the valley.

Thus, according to the patent map display device 1, it is possible to grasp at a glance the technical trends of one's own company and other companies regarding more detailed technical classifications.

（特許庁ホームページ内「国際特許分類（２０１８年バージョン）（仮訳）指針引用）The display format of the IPC complete classification symbol will be described below. The IPC complete classification symbol is a combination of symbols representing sections, classes, subclasses and main groups or subgroups.

(Quoted from the “International Patent Classification (2018 version) (provisional translation) guideline” on the JPO website)

In addition, the patent map display device 1 can enlarge or reduce an area of a predetermined technical classification specified by the user in the patent map 200 displayed on the user terminal 100 . For example, the generation unit 41 generates an enlarged image or a reduced image of the area of the technical classification by the user tapping a position near the area of the predetermined technical classification or the area of the word (keyword, etc.) and rotating it vertically or horizontally. Images can be generated. Then, the enlarged image or reduced image may be configured to be displayed on the user terminal 100 by the display unit 50 . Specifically, the display unit 50 responds to the tap operation by the user to enlarge or reduce the display image of the patent map 200 displayed on the user terminal 100, which is stored in the storage unit 50. The image data may be read, and an enlarged image or a reduced image may be displayed and output.

Next, the generator 41 changes the terrain of the battlefield map 210 according to the number of similar technical information (S13). Specifically, as shown in FIGS. 9 and 10, when the number of similar technical information is equal to or smaller than the first threshold, the generation unit 41 generates a battlefield in a predetermined area where the warrior 220 representing the technical information is placed. The terrain of map 210 can be generated concave. More specifically, when the number of pieces of similar technical information is small (for example, 5 pieces or less), the generating unit 41 converts the terrain of the predetermined area surrounding the warrior 220 representing the technical information arranged on the battlefield map 210 into a valley shape. (See part N in FIG. 10). A tally unit (not shown) tallies the number of cases.

Further, when the number of similar technical information is equal to or greater than the second threshold, the generation unit 41 may generate a convex terrain of the battlefield map 210 in a predetermined area where the warrior 220 representing the technical information is placed. . More specifically, when the number of pieces of similar technical information is large (for example, 20 or more), the generation unit 41 converts the terrain of a predetermined area surrounding the warrior 220 representing the technical information arranged on the battlefield map 210 into a mountain-like shape. (Refer to section M in FIG. 10). The comparison unit 31 determines whether the number of similar technical information is equal to or greater than a predetermined threshold or equal to or less than a predetermined threshold.

According to the patent map display device 1 according to the present modified example, it is possible to change the topography of the map 210 according to the number of similar technical information, so it is possible to grasp the technical trend of the company at a glance.

A control unit (not shown) executes functions implemented by codes or instructions included in a program. They are processors (multiprocessor), ASICs (Application-specific Integrated circuits), and FPGAs (Field programmable Gate Arrays). In addition, in this invention, a control part (not shown) is not limited to these. The control unit (not shown) may include RAM (Random Access Memory), ROM (Read Only Memory), and the like. A control unit (not shown) develops a program stored in the ROM on the RAM and causes the CPU to implement the corresponding process.

By configuring in this way, it is possible to visually grasp the breadth of the right scope of the technology to be evaluated input by the user. It should be noted that the output form of the patent evaluation is different for discoverability of easy infringement and invalidity. In other words, patents with a high degree of similarity have a wide range of rights, are easy to enforce, and are difficult to avoid infringement. On the other hand, there is a possibility that the patent will be invalidated. In this case, the warrior 220 may have a club with a low level as an item. In addition, patents with a low degree of similarity have a narrow scope of rights and are difficult to enforce, making it easier to avoid infringement. On the other hand, it tends to be difficult to invalidate the patent. In this case, the warrior 220 may possess a high-level ax as an item. The storage unit 60 stores various types (modes) of warriors 220 as described above, and these items are associated with respective degrees of similarity. The generation unit 41 is configured to generate items (weapons, etc.) for the warrior 220 according to the level when the character reaches a predetermined level.

In the above description, the patent map display device 1 according to the present embodiment and the modified example expresses the patent map 200 by arranging the warriors 220 on the battlefield map 210 whose topography is the virtual battlefield. However, the present invention is not limited to this.

Furthermore, although the patent map display device 1 according to the present embodiment and the modification has been described as a patent map as a support tool for patent analysis, the present invention is not limited to this. Needless to say, the present invention can be used not only for patent analysis but also as a support tool for intellectual property analysis such as design analysis and trademark analysis. Furthermore, the present invention can be used as a support tool for analysis of non-patent documents such as paper analysis and book analysis other than intellectual property. The content that the user enters in the input field of the user terminal may be a draft of a design registration application, a trademark registration application, etc., a memo containing information about intellectual property, a keyword related to intellectual property, or a created Alternatively, documents such as trademark registration applications, design registration applications, patent applications, utility model registration applications, etc., that are being prepared may be used.

Further, in the patent map display device 1 according to the embodiment and the modification, the patent map 200 displayed on the screen of the user terminal 100 can be enlarged, reduced, rotated, and displayed. As a result, the patent map 200 can be displayed in three dimensions, and the distance relationship between the warriors 220 can be visually grasped as technical information that is difficult to grasp in the patent map 200 displayed in two dimensions. In addition, as shown in FIG. 12, since the patent map 200 can be enlarged, it is possible to grasp the appearance and number of the warriors 220, and it is possible to determine what level the warriors 220 are. It is possible to visually recognize the number of technical information to be processed. Further, the display unit 50 displays what kind of technical information includes many words in an arbitrary predetermined area, for example, as a so-called word cloud so that the higher the appearance frequency of the word, the larger it is displayed. good too.

Further, the patent map display device 1 according to the embodiment and the modified example displays the input content of the invention related to the technical information, the scope of claims, the inventor information, and the applicant information when the warrior 220 placed on the battlefield map 210 is hovered over. The display unit 50 may display and output information indicating the content of the invention related to each piece of technical information.

Furthermore, according to the patent map display device 1 according to the modified example, as in the present embodiment, as shown in FIGS. The terminal 100 may be configured to display and output. The switching is performed by a switching unit (not shown) included in the patent map display device 1, for example.
