Expansion of Claims in CA/CAplus Now Includes Germany, United Kingdom and Russia

During 2022, the availability of Claims data in CA/CAplus patent records will continue to expand. We expect to add four additional authorities per quarter, in Q2-Q4, simplifying your access to Claims data from key patent authorities.

The most recent addition, launching in 1Q2022, makes Claims data available for these authorities:

Authority Coverage Begins in Year Volume of Patents with Claims
(March 2022)
Germany (DE) 1997 397K
Great Britain (GB) 1927 74K
Russia (RS) 1994 276K

Other authorities whose Claims are already provided in CAplus are: China (CN), the EPO (EP), Japan (JP), Korea (KR), USA (US), and WIPO (WO).
