Method for merging applicants or inventors in patent analysis

Abstract

The invention relates to a method for merging applicants or inventors in patent analysis, which comprises the following steps: (1) establishing an appellation database, wherein the database stores anappellation table of each applicant or inventor, each appellation table comprises different appellations of each applicant or the inventor, and each appellation table corresponds to a table name; (2)establishing a corresponding special patent database through retrieval in patent literature of each country according to a preset technical subject; (3) performing retrieval in the special patent database by taking the table name as a retrieval field, matching the patent applicants or patent inventors in the special patent database with each appellation included in the table names, and then marking matched patents; and (4) merging names of the applicants or the inventors on the marked patents through a computer. By the technical scheme, the method can improve the merging efficiency of the applicants or the inventors in the patent analysis greatly.

Description

technical field [0001] The invention relates to a method for merging applicants or inventors in patent analysis. Background technique [0002] Patent analysis has been paid more and more attention by enterprises. The analysis of patent applicants, that is, competitors, has become an important part of the patent analysis work of enterprises. [0003] However, in the patent literature, we will find that the patents actually belong to the same company, but the name of the applicant presents different names in different poses and with different expressions, which is more common in English patent literature. The reason for this situation is that on the one hand, large companies with strong technical strength deliberately apply for patents with the names of subsidiaries that are not familiar to everyone, so as to avoid everyone's attention, so that some companies will not conduct detailed research. , When infringing its patent right, you can get considerable compensation. On the...

Problems solved by technology

At present, in the patent analysis, the merge of applicants or inventors is to put forward the name of the retrieved patent applicants, manually judge, and manually merge one by one, which is time-consuming and labor-intensive for patent documents with a large amount of data. , also error prone

However, some applicants involve a wide range of patent technology fields. When the next patent analysis in a different field encounters the same applicant, it is necessary to repeat the previous manual operation, which seriously reduces the efficiency of patent analysis.
