CAFC Reminds the Patent Office to Play Fair When Issuing New Grounds of Rejection and Evaluating Objective Evidence of Non-Obviousness

Rambus Inc. v. Rea

September 24, 2013

Panel of Moore, Linn, and O’Malley, Opinion by Moore

Summary

The Court of Appeals for the Federal Circuit in Rambus Inc. v. Rea reminds Examiners and the Board of Patent Appeals and Interferences (now the Patent Trial and Appeal Board) that procedural checks remain in place for issuing new grounds of rejection. Examiners and the Board cannot bury a new ground of rejection in a decision, without ensuring that a patent applicant has had a fair opportunity to respond to the rejection. Indeed, whether the applicant has had a fair opportunity to react to the thrust of the rejection is reiterated as the ultimate determination of whether a rejection is considered “new”.

In line with the Federal Circuit’s recent decision in Leo Pharmaceutical Products v. Rea, Rambus is also a reminder that objective evidence of non-obviousness must be given due consideration and weight. Examiners and the Board cannot undercut an applicant’s objective evidence of non-obviousness through an overly stringent interpretation of the nexus and “commensurate in scope” requirements.
