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.

ArcelorMittal v. AK Steel Corp.

November 30, 2012

Panel: Dyk, Clevenger, and Wallach.  Opinion by Dyk.

Summary:

The U.S. District Court for the District of Delaware held that defendants AK Steel did not infringe plaintiffs ArcelorMittal’s U.S. Patent No. 6,296,805 (the ‘805 patent), and that the asserted claims were invalid as anticipated and obvious based on a jury verdict.

ArcelorMittal appealed the district court’s decision.  On appeal, the CAFC upheld the district court’s claim construction in part and reverse it in part.  With regard to anticipation, the CAFC reversed the jury’s verdict of anticipation.  With regard to obviousness, the CAFC held that a new trial is required because the district court’s claim construction error prevented the jury from properly considering ArcelorMittal’s evidence of commercial success.

미국 델라웨어주 연방지방법원 (U.S. District Court for the District of Delaware)은 원고 (ArcelorMittal)가 피고 (AK Steel)를 상대로 낸 특허 침해 소송에서 원고의 특허 (U.S. Patent No. 6,296,805)가 예견가능성 (anticipation) 및 자명성 (obviousness) 기준을 통과하지 못하였다는 배심원의 판단을 바탕으로 피고가 원고의 특허를 침해하지 않았다고 판결하였다.

이에 불복하여 원고는 연방항소법원 (U.S. Court of Appeals for the Federal Circuit)에서 상고 (appeal) 하였으며, 연방항소법원은 지방법원의 청구항 해석 (claim construction)에 대해 일정 부분은 확인하였으나, 나머지 부분은 번복하였다.

예견가능성과 관련하여 연방항소법원은 배심원의 예견가능성 판단과 다른 결정을 내렸다.

자명성과 관련해서는 연방지방법원의 잘못된 청구항 해석으로 인하여 배심원이 원고의 상업적 성공 (commercial success) 증거를 고려하지 않았기때문에 재심 (new trial)이 필요하다고 판결하였다.
