PTAB Gouges Patent Owner and Counters District Court in CBMP Review | Practical Law
In Interthinx v. CoreLogic Solutions, a covered business method patent review, the US Patent Trial and Appeal Board (PTAB) determined that certain claims of an expired patent did not cover patent-eligible subject matter and were anticipated or obvious in view of the prior art. This decision came despite an earlier district court decision that entered judgment upholding the validity of certain of these patent claims.
