Dealing with Different Embodiments of the Specification
| December 26, 2012
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。

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.

CAFC discusses interplay between means-plus-function and claim differentiation
| November 19, 2012
Icon Health & Fitness, Inc. v. Octane Fitness, LLC.
October 14, 2012
PROCEDURAL SUMMARY
ICON Health & Fitness, Inc. (“ICON”) owner of USP 6,019,710 (the “’710 patent”) sued Octane Fitness (“Octane”) for infringement in the United States District Court for the District of Minnesota. The District Court granted summary judgment of non-infringement of claims 1–5, 7, and 9–10 of the ’710 patent by concluding that the “stroke rail” and “means for connecting” limitations were absent in Octane’s Q45 and Q47 machines. On appeal, the CAFC agreed with the District Court’s claim construction and affirmed the District Court’s holding of non-infringement.

Flo Heathcare Solutions v. Kappos
October 23, 2012
Panel: Newman, Plager, and Wallach. Opinion by Wallach.
PROCEDURAL SUMMARY
The patentee sued the defendant for infringement. The defendant then requested inter partes reexamination of the patent. The trial judge stayed the infringement action, pending completion of the reexamination. The patent reexamination examiner and the Patent Office Board rejected the claims as being anticipated by the prior art. On appeal, the CAFC disagreed with the PTO Board’s claim construction; but even under the CAFC’s claim construction, it found that the claims were anticipated and therefore affirmed the PTO’s rejection of the claims

Apple is bit at CAFC: The Court reversed and remanded a preliminary injunction obtained at the District Court against Samsung’s Galaxy Nexus Smartphone
| October 17, 2012
Apple Inc. v. Samsung Electronics, Ltd. et al.
Decided: October 11, 2012
Panel: Prost, Moore, and Reyna. Opinion by Prost.
Summary
The CAFC reversed the District Court’s finding that there was irreparable harm to Apple by allowing sales of the Galaxy Nexus. The CAFC held that there was an insufficient causal nexus between the claimed invention and the sales of the product. The Court also addressed Apple’s likelihood of success to interject claim construction.

Burden of persuasion in the post-MedImmune world
| September 27, 2012
Medtronic v. Boston Scientific Corporation, Guidant Corporation and Mirowski Family Ventures
September 18, 2012
Panel: Lourie, Linn, Prost. Opinion by Linn.
Summary
This decision discusses who carries the burden of persuasion in the post-MedImmune world. This question arises as a consequence of the Supreme Court’s decision in MedImmune, Inc. v. Genentech, Inc., 549 U.S. 118 (2007). In MedImmune, the Supreme Court found declaratory judgment jurisdiction even though the declaratory judgment plaintiff-licensee continued to make royalty payments pursuant to a license. The Court reasoned that a licensee should not be forced to cease royalty payments and risk infringement liability before the licensee can challenge the extent of coverage of the license.
The district court entered judgment of non-infringement in favor of Medtronic and judgment of validity and enforceability in favor of Mirowski Family Ventures (MFV). MFV appeals the judgment of non-infringement and Medtronic cross appeals the district court’s claim construction. The CAFC vacates the district court ruling and remands.

Can an open-ended claim range be enabled?

Magsil Corp. and MIT v. Hitachi Global
August 14, 2012
Panel: Rader, O’Malley, Reyna. Opinion by Rader.
Summary
The U.S. District Court for the District of Delaware granted summary judgment finding claims 1-5, 23, 26 and 28 of appellants’ U.S. Patent No. 5,629,922 (the ‘922 patent) invalid as a matter of law for lack of enablement and therefore non-infringed. At issue was whether the specification enabled the broad scope of the claimed “open-ended” range of values having a lower threshold, but no upper limit, defined by “a change in the resistance by at least 10% at room temperature”.
Magsil appealed the district court’s decision. On appeal, the CAFC affirmed the district court’s finding that claims 1-5, 23, 26 and 28 of the ‘922 patent are invalid for lack of enablement.

CAFC pointers on proving lack of “substantial non-infringing uses” in pleading contributory infringement
| June 20, 2012
Toshiba Corporation v. Imation Corp.
Jun 11, 2012
Panel: Dyk, Schall, and Moore. Opinion by Moore. Dissent by Dyk.
Summary:
(1) Grant of summary judgment of non-infringement as to contributory infringement of ‘751 patent affirmed because plaintiff did not meet burden of proof that there was a lack of substantial non-infringing uses.
(2) Grant of summary judgment of non-infringement as to induced infringement of ‘751 patent vacated because district court erred as a matter of law in holding that the existence of a substantial non-infringing use precludes a finding of induced infringement.
(3) Grant of summary judgment of non-infringement of ‘966 patent vacated because it was based on erroneous claim construction.
(4) No clear “take away” on claim construction from discourse between majority and dissent.

Means-Plus-Function: The Achilles’ Heel
| May 9, 2012
Noah Systems, Inc. v. Intuit, Inc.
April 9, 2012
Panel: Rader, O’Malley and Reyna. Opinion by Judge O’Malley
Summary
This decision illustrates that a patent could become invalidated even after surviving challenges of reexamination, which strengthen the presumption of validity, when a challenger discovers the Achilles’ Heel of a means-plus-function claim element resulting in a summary judgment of invalidity by the CAFC. Noah appeals the granting, by the United States District Court for the Western District of Pennsylvania (DC), of Intuit’s Motion for Summary Judgment of Invalidity of USP 5,875,435 (the ‘435 patent) based on indefiniteness for a means-plus-function claim element without the DC hearing evidence of how one of skill in the art would view the specification. The CAFC affirms by finding that the specification discloses no algorithm when the specification discloses an algorithm that only accomplishes one of two identifiable functions performed by the means-plus-function limitation.

Revisiting Therasense, CAFC finds that an inventor’s subjective belief that submission of documents was unnecessary may not be sufficient to avoid a showing of intent to deceive

Therasense判決に基づくCAFC判決；書類のIDS提出は必要ではないとする発明者の主観だけでは欺瞞の意図の立証を避けるのには十分ではないかもしれない。
Aventis Pharma S.A. and Sanofi-Aventis U.S. LLC v. Hospira Inc. and Apotex Inc.
April 9, 2012
Panel: Linn, Dyk, and Prost; Opinion by Prost
Summary:
The court found that the patents were invalid over withheld references, and unenforceable for inequitable conduct.
If the patentee did not narrow the ordinary meaning of a claim term by either acting as its own lexicographer or disclaiming claim scope either in the specification or during prosecution, that claim term cannot be interpreted more narrowly than its ordinary meaning.
If the claims at issue are found invalid over a withheld reference under the clear and convincing evidence standard, then the withheld reference is found but-for material under the preponderance of evidence in Therasense; in this case, the materiality requirement was met since the patents were invalid based on the withheld references.
The witness’ explanation that that he believed he did not need to disclose the references to the PTO may not be sufficient to show that there was no specific intent to deceive the PTO because that finding was not the single most reasonable inference that could be drawn, unless the testimony is credible and the evidence presented is supported. The reference disclosing the information that shaped the inventive thinking should be cited, and there is no justification for telling the PTO about the prior art disclosing the problem an inventor examined while concealing key prior art disclosing the solution he chose.
