Applicant’s failure to request claim construction under §112, 6th paragraph may invoke waiver of such claim construction
| January 23, 2013
In re Avid Identification Systems, Inc.
January 8, 2013
Panel: Lourie, Clevenger and Bryson. Opinion by Lourie. Dissent by Clevenger.
Summary:
The Examiner rejected claims of a patent at issue, and the PTO board maintained the rejection finding that a means-plus function limitation was found in prior art where its broadest reasonable meaning was given. CAFC affirmed the PTO decision, and denied the Applicants’ request for a claim construction under § 112, 6th paragraph, instead of the broadest reasonable interpretation. CAFC reasoned that the Applicants waived that claim construction by failing to raise the issue during the procedure in the PTO. The dissenting opinion pointed out that the claim construction according to § 112, 6th paragraph is mandatory as the statutory requirement where the claim term clearly invokes the application of § 112, 6th paragraph.
出願人はクレームが自明であるとして拒絶した特許庁審判部の判断を不服として、ＣＡＦＣに控訴した。問題のクレームには、ミーンズプラスファンクション（”means for”の用語を用いた限定 ）を記載がある。そのような記載があると通常、特許法112条第6パラグラフの適用があり、その機能限定は明細書に開示されている構造もしくはそれと均等な構造を記載していると限定解釈される。しかしながら、本件では、特許庁審査官および審判部は、そのミーンズプラスファンクションの限定を、一般的な構造限定のときのように合理的な範囲で最も広い意味（broadest reasonable meaning）の基準を用いて解釈した。この広い解釈に基づいてその機能限定は先行技術に記載されていると特許庁は判断した。この経緯に関してＣＡＦＣは、出願人は特許庁の手続きにおいて112条第6パラグラフの適用を自ら主張しなかったためその機会を放棄したと判断し、出願人の主張を退けた。ＣＡＦＣ裁判官の１人は、112条第6パラグラフの適用は制定法上の要求であり、出願人や審査官が同法に基づく限定解釈を要求しなくても先ずその解釈を採用すべきであるとの反対意見を述べた。

Elimination of false marking actions does not violate the Due Process Clause of the U.S. Constitution

Brooks v. Dunlop Manufacturing
December 3, 2012
Panel: Newman, Prost, Moore. Opinion by Prost.
Procedural Summary
Lawyer Brooks sued Dunlop under 35 U.S.C. § 292 for falsely marking a guitar string winder with the number of a patent that had both expired and been found invalid. During the pendency of the law suit, Congress passed the America Invents Act (AIA) that, inter alia, eliminated false marking actions, except under very limited circumstances.
The trial judge therefore dismissed Brooks’ case, despite Brooks’ argument that the AIA’s elimination of false marking cases violated the Due Process Clause of the U.S. Constitution. On appeal, the CAFC agreed with the trial judge and therefore affirmed his dismissal of the case.

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。

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.

Method Claim Survives Over MPF Claim’s Demise Under Aristocrat
| November 28, 2012
ePlus, Inc. v. Lawson Software, Inc.
November 21, 2012
Dyk, Prost, O’Malley. Opinion by Prost.
Summary:
This case serves as a reminder of the importance of having different claim types. ePlus’ jury verdict of infringement of two systems claims was vacated because the Federal Circuit found one means-plus-function element recited therein to lack the requisite corresponding structure being disclosed in the specification, thereby rendering the claims indefinite under 35 USC §112, second paragraph. However, the infringement of a similar method claim reciting the same function as the means-plus-function element was affirmed.

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.
