35 U.S.C. §102 : CAFC Alert

The CAFC Finds the Board’s Claim Construction to Be Unreasonably Broad

In re Power Integrations, Inc.

March 19, 2018

Before Moore, Mayer, and Stoll.  Opinion by Mayer.

Summary

Power Integrations, Inc. (“Power Integrations”) appeals a remand decision of the Patent Trail and Appeal Board (“Board”) rejecting claims 1, 17, 18 and 19 of US Patent No. 6,249,876 (the ‘876 patent) as anticipated under 35 U.S.C. §102(b).  On appeal, the CAFC found the board’s claim construction to be unreasonably broad.  Because the Board’s anticipation rejection was based on an unreasonably broad claim construction, the CAFC reversed.

要旨:

連邦巡回控訴裁判所(CAFC)の判決である。先に米国特許庁審判部へ差し戻され、米国特許庁審判部が再度判断を下したその判断の適否が争われた。米国特許庁審判部が広いクレーム解釈に基づいて「新規性なし」と判断した審決をCAFCは覆した。CAFCは、米国特許庁審判部のクレーム解釈はいわゆるBRI(Broadest Reasonable Interpretation)ではなく、Unreasonably(不当)に広いと判断した。そのような不当に広いクレーム解釈に基づいて引例の開示が当てはめられた新規性の判断が覆された。

Power Integrations v. Lee

August 12, 2015

Before: Moore, Mayer, Linn, opinion by Mayer

Power Integrations challenged a decision of the Board of Patent Appeals and Interferences (“board”) affirming the rejection of claims 1, 17, 18 and 19 of US Patent No. 6,249,876 (the ‘876 patent) as anticipated under 35 U.S.C. §102(b). The board’s construction of the claim term “coupled” was not adequately explained. The court vacated and remanded the board’s decision, holding only that the board on remand should carefully and fully assess whether the disputed claims of the ’876 patent are anticipated by the prior art, setting out its reasoning in sufficient detail to permit meaningful appellate review.
