A new patent analysis method based on enterprise collaboration was put forward to better use patent resources for enterprise innovation. A patent analysis platform prototype based on enterprises collaboration was constituted, which can support accurate and complete patent search by constituting and improving the ontology database. The enterprises are encouraged to upload their private patent information by incentive mechanism and confidential mechanism. Patent information in the platform database was analyzed. In addition, the platform takes advantage of relations between product technique classification and international patent classification(IPC) to form the product based patent technique classification database.An application in a digital television enterprise showed that associate patents were found by patents combination analysis with different enterprises, so as to achieve the patent collaboration, patent sharing and patent pool between enterprises.
