Method and System for patent information service of assignee unit

摘要

A patent information service system for hierarchically integrating assignee-based and inventor-based patent information service systems, and a method thereof are provided to automatically extract domestic/foreign patent information related to an assignee and/or an inventor by automatically constructing/integrating the assignee-based and inventor-based patent information service systems. Assignee information including an assignee is checked from a patent information database, and patents applied or registered by the checked assignee are searched from the patent information database(S1620). A hierarchically integrated assignee-based patent information service system is constructed when the patent documents are searched(S1630). Inventor information registered as an inventor of the patent documents is extracted(S1660), and a hierarchically integrated inventor-based patent information service system is constructed by using the extracted inventor information(S1670). The inventor-based patent information service system manages patent information registered by the inventor by using an application number as a key value. The patent information includes at least one of bibliographic information of the patent information corresponding to the application number.
