Federal Circuit Again Reminds PTAB that BRI Must Be Reasonable

Last fall, the Federal Circuit reversed a PTAB decision that affirmed an Examiner’s rejection of various claims in an ex parte reexamination because the Examiner’s interpretation of the claims, which the PTAB upheld, was unreasonably broad.

In CRFD Research Ltd. v. Matal, No. 2016-2198 (Fed. Cir. Dec. 5, 2017), the Federal Circuit determined that the PTAB erred in its obviousness analysis, in part by failing to consider an argument the IPR petitioner made in a ground that the PTAB determined was “redundant” to the instituted grounds.

PTAB Not Always Bound By Previous Court Decisions Regarding Patent Validity

Cases to Watch

Pending Supreme Court Decisions The Supreme Court will decide during its October 2017 term “Whether inter partes review—an adversarial process used by the Patent and Trademark Office (PTO) to analyze the validity of existing patents—violates the Constitution by extinguishing private property rights through a non-Article III forum without a jury.” Oil States Energy Services, LLC … Continue Reading

Error in Claim Construction Leads to Reversal of IPR Decision and Cancelation of Claims

Two recent Federal Circuit decisions illustrate how an error in construing claims may lead the court to reverse a PTAB final written decision. In Organik Kimya AS v. Rohm & Haas Co., the Federal Circuit determined that the PTAB correctly construed the disputed claim term, “swelling agent,” and therefore affirmed the PTAB’s decisions upholding the … Continue Reading

Patent Owner’s Optional Preliminary Response Avoids IPR, But Dooms Infringement Action

Earlier this year, the Federal Circuit held “that statements made by a patent owner during an IPR proceeding, whether before or after an institution decision, can be considered for claim construction and relied upon to support a finding of prosecution disclaimer.” Aylus Networks, Inc., v. Apple Inc., Appeal 2016-1599 (Fed. Cir. May 11, 2017). In … Continue Reading

Petitioner Made Rebuttal Argument in Reply, Not an Improper New Argument

PTAB rules prohibit raising new arguments in a reply brief, but it can be difficult to distinguish between an improper reply argument and a proper rebuttal. In Idemitsu Kosan Co. v.

Late Payment of Petition Fee Thwarts IPR

If a Petitioner does not timely file the required petition fee, an IPR will not be instituted. In Cultec, Inc. v. Stormtech LLC  [Case No. IPR2017-00526, Paper 14 (July 17, 2017)], consistent with earlier decisions, the Board denied institution of an IPR because the Petitioner, Cultec, Inc., did not pay the required filing fee until … Continue Reading

How to Overcome a Section 112 ¶ 6 Means-Plus-Function Presumption

PTABWatch Takeaway: Claims that recite the term “means” may trigger the means-plus-function presumption under pre-AIA 35 U.S.C. § 112 ¶ 6 (Section 112(f) of the AIA), but the presumption can be overcome where: (1) the means term itself recites structure; (2) that structure is “common parlance” to those of ordinary skill in the art; and … Continue Reading
