Common Citation Document (CCD)

Keeping track of numerous parallel applications around the world has often been a challenge for applicants, even though many patents can be linked as a „family“ through common priority dates. Two initiatives from the EPO have greatly helped users in 2013. The broadened scope of the Common Citation Document (CCD) now enables users to view the search results from all IP5 offices as well as from several EPO member state offices via a single interface.
