Hereinafter, a specific operation of the patent value calculation apparatus according to the present embodiment will be described.

  Assume that a large number of registered patent documents are stored in the patent information storage unit 102. Here, it is assumed that each patent document has a file name consisting of a patent number (for example, “JP12345”). Further, it is assumed that the patent document has information of claims, patent specifications, and IPC (International Patent Classification).

The patent attribute information storage unit 103 holds two patent attribute information management tables shown in FIG. FIG. 4A is a patent attribute information management table having one or more patent attribute information having technical terms and attribute values (unit: million yen). FIG. 4B is a patent attribute information management table having at least one patent attribute information having an IPC and an attribute value (unit: million yen). That is, for example, in FIG. 4A, a patent corresponding to the technical term “power supply” (a patent for a technique related to “power supply”) potentially has a value of 10 million yen (has a default). To do. Also, in FIG. 4B, a patent classified as IPC “G06F 3/14” means that it potentially has (by default) a value of 5 million yen.
In this situation, it is assumed that the user inputs a calculation instruction, which is an instruction for calculating the value of the patent stored in the patent information storage unit 102, to the patent value calculation apparatus.
Next, the reception unit 101 receives a calculation instruction.

  Next, the patent attribute acquisition unit 104 sequentially reads and analyzes the patent documents in the patent information storage unit 102, and acquires patent attributes. Here, the patent attribute acquisition unit 104 calculates the appearance frequency of each patent attribute in the patent attribute information management table of FIG. 4A in each patent document. Then, the patent attribute having the highest appearance frequency is acquired and temporarily stored as the patent attribute 1 of the patent document. Next, the patent attribute acquisition unit 104 acquires the IPC included in the patent document as the patent attribute 2 of the patent document, and temporarily accumulates it.

  Next, the patent attribute acquisition unit 104 acquires the attribute value corresponding to the same patent attribute as the patent attribute 1 from FIG. 4A and displays the attribute value corresponding to the same patent attribute as the patent attribute 2. 4 (b) and the sum of two attribute values is calculated. Assume that the sum of these two attribute values is an attribute value indicating the economic standard value of the patent document. With the above processing, the patent attribute acquisition unit 104 obtains the patent attribute value table of FIG. The patent attribute value table has one or more records having “ID”, “patent number”, “patent attribute 1”, “patent attribute 2”, and “attribute value”. “ID” is information for identifying a record and exists for record management in the table. The “patent number” is information for identifying a patent document. The “attribute value” indicates a reference value of the value (unit: million yen) of the patent identified by “patent number”. Since the value of the patent at this stage is determined from the technical field of the patent, it is generally the value of the patent from an economical viewpoint. The patent attribute acquisition unit 104 calculates the sum of the two attribute values as the attribute value, but may calculate an average value of the two attribute values or a value obtained by weighting the two attribute values.

  Next, the patent document analysis means 1061 of the intermediate value information calculation unit 106 performs language analysis on each patent document, and for each patent document, “minimum number of constituent elements”, “minimum number of characters of claim”, “number of claims”, “category” The number of expansions, “maximum nesting level”, “number of characters in claims”, “number of pages of embodiment”, “number of characters of embodiment”, “number of cited references”, and the like are acquired.

  The invention essential extractability value calculating means 10621 calculates the invention essential extractability value using, for example, “minimum number of constituent elements” and “minimum number of characters in claims” as parameters. The invention essential extractability value calculating means 10621 calculates the invention essential extractability value by, for example, the calculation formula “a × minimum number of components + b × minimum number of characters in claims” (a and b are constants). Further, the invention essential extractability value calculating means 10621 normalizes the invention essential extractability value so that the highest score is 100 points.

  Next, the invention development value calculation means 10622 calculates the invention development value using, for example, “number of claims”, “number of categories development”, and “maximum nesting level” as parameters. The invention developability value calculating means 10622 calculates the invention developability value by, for example, a calculation formula “c × number of claims + d × category development number + e × maximum nest level” (c, d, e are constants). . In addition, the invention development value calculation means 10622 normalizes the invention development value so that the highest score is 100 points.

  Next, the feasible security value calculating unit 10623 calculates the feasible security value using “number of characters in the claims” and “number of characters in the embodiment” as parameters. In addition, the feasibility guarantee value calculation unit 10623 calculates the feasibility guarantee value by, for example, the calculation formula “number of characters in the embodiment / number of characters in the claims”. In addition, the feasibility guarantee value calculation unit 10623 normalizes the feasibility guarantee value so that the highest score becomes 100 points.

  Next, the toughness value calculating means 10624 calculates the toughness value using, for example, “number of cited references” as a parameter. Note that the toughness value calculating means 10624 calculates the toughness value by, for example, the calculation formula “f × number of cited documents” (f is a constant). Further, the toughness value calculating means 10624 normalizes the toughness value so that the highest point becomes 100 points.

  Next, the intermediate value information calculation means 1063 calculates intermediate value information for each patent document, using the calculated invention essence extractability value, invention expandability value, feasibility guarantee value, and toughness value as parameters. Here, for example, the intermediate value information calculation means 1063 calculates, for each patent document, “0.4 × invention extractability value + 0.4 × invention developability value + 0.1 × practicability guarantee value + 0.1 × strength. It is assumed that intermediate value information is calculated based on the “sex value”. That is, the intermediate value information calculation unit 1063 calculates intermediate value information by weighting each characteristic value. Through this processing, the intermediate value information calculation unit 106 obtains the intermediate value information calculation result table of FIG. The intermediate value information calculation table has characteristic values and intermediate value information corresponding to each patent document. Note that the intermediate value information calculation unit 1063 may use an average value of the characteristic values as intermediate value information.

  Next, the patent value calculation unit 107 calculates the patent value for each patent document based on the intermediate value information of each patent document and the attribute value of each patent document. For example, the patent value calculation unit 107 calculates the patent value of each patent by “attribute value × intermediate value information / 100”. Then, the patent value calculation unit 107 obtains the patent value management table of FIG. The patent value management table has one or more records having attribute values of “ID”, “patent number”, and “patent value (million yen)”. The patent value calculation unit 107 can calculate the value of each patent. In addition, the calculation formula which the patent value calculation part 107 performs is not ask | required.

  Next, the patent value output unit 108 outputs the patent value. For example, the patent value output unit 108 may output the patent value management table of FIG. 7 as it is, and may output the value of each patent individually, or calculate the sum of the patent values of all the patents, May be output. Further, the patent value output unit 108 may output the patent value as a number, or may output the patent value as a graph or a design. Further, the patent value output unit 108 may sort and output the records in order of high patent value and low order.

As described above, according to the present embodiment, the value of a highly accurate patent can be calculated. In other words, the analysis based on the patent attribute information is mainly the analysis of the patent value from an economic and technical viewpoint, and the analysis based on the patent characteristic values (such as the invention essentiality extractability value) is mainly legal and technical. It is an analysis of patent value from a general viewpoint. In other words, this analysis method can analyze and output the patent value from an economic, technical, and legal perspective.
In addition, according to the present embodiment, a comprehensive analysis that analyzes patent documents and obtains a patent attribute that is a result of classifying the patent, and a micro analysis that analyzes the patent documents and calculates the characteristic value of the patent are combined. Patent value can be calculated.
The attribute values, characteristic values, intermediate value information, patent value calculation formulas, parameters, and the like described in this embodiment are examples, and it goes without saying that other calculation formulas and parameters may be used.

  In addition, according to this Embodiment, although the patent value evaluation apparatus was demonstrated so that it might operate | move stand-alone, you may operate | move with the system in a server client model.
