Method, system, and program for evaluating intellectual property right
The present invention performs more realistic evaluation of an intellectual property right in which a value in business and a relation in business between enterprises are taken into account. The present invention provides a method, system, and program for preserving the business value of an enterprise which is an applicant, the business value of an enterprise which is an applicant of a source-of-citation patent application, and a relation in business between the two enterprises in a database, and calculating the evaluation index of a patent by reflecting the preserved value.
1. An intellectual property evaluation method executed by a computer system having a patent information store and an inter-company relation store,
wherein
the patent information store contains information on patent applicants and citation relationship between patents, and
the inter-company relation store contains relation information among patent applicants,
the method comprising:
retrieving data about an applicant of a first patent from the patent information store,
retrieving data about applicants of more than one second patents for which the first patent was cited as a prior art,
retrieving an inter-company relation index between the applicant of the first patent and each of the applicants of the more than one second patents from the inter-company relation store, and
modifying an evaluation index of the first patent using evaluation index increments calculated for each of the applicants of the more than one second patents using the inter-company relation index.
2. The method according to claim 1 ,
wherein:
the computer system further comprises a patent evaluation index store, the method further comprising:
storing the evaluation index calculated using the method according to claim 1 in the patent evaluation index store, and
modifying the evaluation index of the first patent using evaluation index increments read from the patent evaluation index store for each of more than one second patent applicants.
3. The method according to claim 1 further comprising:
reading more than one patent publications, and
setting, based on data of an applicant and patent classification of each of the more than one patent publications, business relation coefficients stored in the inter-company relation store.
4. A computer apparatus comprising:
a memory storing a patent information store and an inter-company relation store,
wherein
the patent information store contains information on patent applicants and citation relationship between patents, and
the inter-company relation store contains relation information among patent applicants; and
a hardware processor implementing a patent evaluator configured for
retrieving data about an applicant of a first patent from the patent information store,
retrieving data about applicants of more than one second patents for which the first patent Was cited as a prior art,
retrieving an inter-company relation index between the applicant of the first patent and each of the applicants of the more than one second patents from the inter-company relation store, and
modifying an evaluation index of the first patent using evaluation index increments calculated for each of the applicants of the more than one second patents using the inter-company relation index.
5. The computer apparatus according to claim 4
wherein:
the patent evaluator further configured to:
store the evaluation index calculated in a patent evaluation index store, and
calculate the evaluation index of the first patent using evaluation index increments read from the patent evaluation index store for each of the applicants of the more than one second patents.
6. The computer apparatus according to claim 4 ,
the patent evaluator further configured to:
read more than one patent publications, and
set, based on data of an applicant of each of the more than one patent publications and patent classification data, at least part of business relation coefficients stored in the inter-company relation store.
7. A non-transitory computer readable medium that stores an intellectual property evaluation computer program executed by a computer system having a patent information store and an inter-company relation store,
wherein
the patent information store contains information on patent applicants and citation relationship between patents, and
the inter-company relation store contains relation information among patent applicants,
the program comprising instructions for:
retrieving data about an applicant of a first patent from the patent information store,
retrieving data about applicants of more than one second patents for which the first patent was cited as a prior art,
retrieving an inter-company relation index between the applicant of the first patent and each of the applicants of the more than one second patents from the inter-company relation store, and
modifying an evaluation index of the first patent using evaluation index increments calculated for each of the applicants of the more than one second patents using the inter-company relation index.
8. The non-transitory computer readable medium according to claim 7 ,
the program further comprising instructions for:
storing the evaluation index calculated in a patent evaluation index store, and
modifying the evaluation index of the first patent using evaluation index increments read from the patent evaluation index store for each of more than one second patent applicants.
9. The non-transitory computer readable medium according to claim 7 ,
the program further comprising instructions for:
reading more than one patent publications, and
selling, based on an applicant in each of more than one patent publications and patent classification data, at least part of business relation coefficients stored in the inter-company relation store.
