Dealing with Different Embodiments of the Specification

Sandisk Corp. v. Kingston Tech. Co., Inc.
October 9, 2012
Panel: Prost, Reyna and Wallach. Opinion by Prost. Dissent by Reyna.
Summary
The claim construction of the term “relative time” caused the issue whether one of two different embodiments of the specification should be excluded from the scope of literal infringement. The district court excluded the second embodiment, focusing on the claim term “time.” CAFC disagrees, emphasizing the significance of the claim term “relative.” Judge Reyna dissents.
明細書が2つの実施例を含んでいる場合に、クレームの文言が両方の実施例をカバーしているのか、それとも片方の実施例は除外されるべきかが問題となった事件である。この問題は、クレームに記載された「相対的な時間」(relative time)の文言解釈をどのように行うかによって判断が分かれた。地裁ならびにdissent(反対意見)は、クレームの「時間」(time)を厳格に解釈して第2実施例を除外すべきと判断した。CAFCは、クレームの「相対的」(relative)に重きを置き、第2実施例を除外すべきでないと判断した。「両方の実施例がクレームでカバーされる」という一言が明細書に含まれていれば、この問題は回避できたと思われる。

Intel Corp. v. Negotiated Data Solutions, Inc.
December 17, 2012
Panel: Prost, Wallach and Linn. Opinion by Linn.
Summary
Intel and National Semiconductor Corp. (“National”) entered into a cross-licensing agreement. The agreement gave Intel rights to National’s patents and patent applications having an effective filing date during the period in the agreement which lasted from 1976 to 2003. This case deals with four patents that were covered under the agreement. National assigned these patents to Vertical Networks, Inc. (“Vertical”) in 1998. Vertical then filed broadening reissue applications for three of the patents. In 2003, Vertical assigned the original patents and the reissue applications to Negotiated Data Solutions, Inc. (“N-Data”). In 2005 and 2006, well after the agreement expired, the PTO issued reissue patents to N-Data. The issue in this case is whether the agreement, which licenses National patents to Intel, automatically extends to any reissue patents that are derived from those licensed National patents. The CAFC held that the license agreement extends to the full scope of any coverage available by way of reissue for the invention disclosed.

The Fox Group, Inc. v. Cree, Inc.
November 28, 2012
Panel: Newman, O’Malley, and Wallach. Opinion by Wallach. Dissent by O’Malley.
Summary:
(1) Summary judgment in favor of defendant was affirmed with respect to asserted claims because (a) defendant was first to reduce to practice the claimed SiC single crystal, and (2) plaintiff did not produce sufficient evidence raising genuine issue of material fact to show that defendant suppressed or concealed the invention.
(2) Holding that unasserted claims were invalid was vacated.

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.
