INPADOC Calculated Expiration Date

Topic: Patents

Level: Advanced

Language: English

The INPADOC databases on STN have been enhanced with calculated expiration dates for granted IP rights of major patent authorities worldwide. This data enhancement offers new options to identify patents which are potentially in force. Calculated expiration dates help users to narrow down FTO search results to active patent families and eliminate old patents which have naturally expired.
