In Matthews International Corporation v. Vandor Corporation, No. 2017-1889 (Fed. Cir. Mar. 27, 2018) (non-precedential), the Federal Circuit affirmed the PTAB’s final written decision to uphold the claims of Vandor’s patent that Matthews challenged in inter partes review. The claims at issue “are directed to ‘a casket arrangement’ made of pliable material, such as cardboard,” in which side and end panels of the casket can be folded to allow the casket to be reconfigured and condensed for ease in shipping and storage. According to the PTAB and the Court, Matthews failed to prove by a preponderance of the evidence that the claims were anticipated by the prior art, even though the claims may be obvious.

Federal Circuit Reverses, i.e. Overturns, Board’s Anticipation Decision Due to Overbroad Claim Construction
In TF3 Ltd. v. Tre Milano, LLC, Appeal 2016-2285 (Fed. Cir. July 13, 2018), the Federal Circuit reversed the Patent Trial and Appeal Board’s final written decision canceling claims directed to a hair styling device as anticipated by prior art. The court concluded that the Board improperly broadened two claim terms beyond the description in the patent specification. Using the correct claim construction, the court concluded that prior art does not anticipate the claims. In part, the court relied upon the abbreviation “i.e.” in determining the proper scope of the claim terms.

Mixed Result Upheld in Personal Audio IPRs
The Federal Circuit upheld the PTAB’s mixed decisions in IPRs filed by Google to challenge claims of two Personal Audio LLC patents asserted against Apple, Samsung, Amazon and Research in Motion, in addition to Google. Google LLC v. Personal Audio LLC, Nos. 2017-1162, -1166, -2110, -2111 (Fed. Cir. Aug. 1, 2018) (non-precedential).

Play the Claim
Monsanto Technology LLC v. E.I. DuPont de Nemours & Co. Appeal 2017-1032 (Fed. Cir. Jan. 5, 2018), illustrates “[t]he life of a patent solicitor has always been a hard one.” [1] The case concerns an inter partes reexamination of a Monsanto patent in which the Patent Office concluded the claimed subject matter was inherently described in an earlier DuPont patent. The Patent Office reached this conclusion because DuPont presented during the reexamination its unpublished data regarding experiments described in its earlier patent. The Federal Circuit affirmed.

Collateral Estoppel Not Limited to Identical Claims
The equitable doctrine of collateral estoppel protects a party from having to re-litigate an issue that has already been fully and fairly adjudicated. In Nestlé USA, Inc. v. Steuben Foods, Inc. the Federal Circuit said that application of collateral estoppel is not limited to construing only identical patent claims; but instead, it extends to terms across related patents. Case No. 2017-1193 (Fed. Cir. Mar. 13, 2018).

Is the PTAB Bound by a Prior Federal Circuit Claim Construction?
In Knowles Electronics LLC v. Cirrus Logic, Inc., No. 2016-2010 (Fed. Cir. Mar. 1, 2018), the Federal Circuit affirmed a PTAB decision that upheld an examiner’s rejection of claims for anticipation in an inter partes reexamination (IPX). The same claims had earlier been challenged, and determined to be not invalid (over different prior art), in an ITC decision that was also affirmed by the Federal Circuit. MEMS Tech. Berhad v. Int’l Trade Comm’n, 447 F. App’x 142 (Fed. Cir. 2011). The decision in the IPX appeal turned on construction of a particular claim term (“package”), and according to a dissent authored by Judge Newman, the court should have reversed the PTAB’s decision due to claim preclusion, because the court had earlier construed the same term differently.

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 re Smith International, Inc., Appeal No. 2016-2303 (Fed. Cir. Sept. 26, 2017). The court’s decision is noteworthy because it reinforces the bounds of the broadest reasonable interpretation claim construction standard the Patent Office must apply when assessing patentability, bounds that do not encompass the broadest possible interpretation.

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 patentability of challenged claims directed to processes for preparing emulsion polymers. In contrast, in Owens Corning v. Fast Felt Corp., decided on the same day, the court determined that the PTAB erred in construing the term “roofing or building cover material” too narrowly, and thus reversed the PTAB’s decision canceling claims directed to methods of applying polymer “nail tabs” on roofing and building cover material.

Federal Circuit Overturns PTAB’s Finding of Patent Validity
In a split opinion in Homeland Housewares, LLC v. Whirlpool Corporation, the Federal Circuit has again overturned a final written decision issued by the PTAB determining that challenged claims in an IPR were not unpatentable, a development that should at least cast doubt on the validity of patents that survive challenges at the PTAB.
Homeland initially petitioned the PTAB for an inter partes review of all claims of U.S. Patent No. 7,581,688 (“the ’688 patent”), assigned to Whirlpool, arguing that the claims were invalid as anticipated by U.S. Patent No. 6,609,821 (“the ’821 patent”).

PTAB Correctly Construed “Said” and Canceled Claims—but Was the Patent CBM Eligible?
In a CBM appeal, TransPerfect Global, Inc. v. Matal, No. 2016-1121 (Fed. Cir. July 12, 2017) (non-prec.), the Federal Circuit determined that the PTAB correctly construed the word “said” in the claim term “said hyperlink,” and determined that TransPerfect’s challenged claims were unpatentable for lack of written description. The court’s claim construction analysis is thorough and well supported, but the treatment of the challenged patent as CBM-eligible appears to be inconsistent with Federal Circuit precedent.
