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).
