Patent Global Dossier available in Espacenet
The advantage is that many more filewrappers are made available in Espacenet via the Global dossier. Espacenet gives access to all available documents, whereas filewrappers in the Register have to have an EP family member. For example a Chinese patent application having a Chinese priority filing and no other family member, can be retrieved in Espacenet.
Currently the Global dossier service is active for Chinese patent applications filed as from 10 February 2010 via the State Intellectual Property Office of the People’s Republic of China (SIPO). The filewrappers are visible in Espacenet within four weeks of their publication at SIPO.
