In Donner Technology, LLC v. Pro Stage Gear, LLC, Appeal. No. 20-1104 (Fed. Cir. Nov. 9, 2020), the Federal Circuit vacated and remanded the PTAB’s decision that the Petitioner, Donner Technology, did not sufficiently prove unpatentability because a printed publication on which it relied was not sufficiently analogous to the claimed subject matter.  In doing so, the Federal Circuit reminded the PTAB, and practitioners alike, of the proper standard for determining whether a reference is “analogous,” as well as how to appropriately apply that standard.

A patent interference is an adversarial proceeding where each party is trying deprive its opponent of a patent on an invention that that the Patent Office has already decided is patentable. Long after the AIA became effective to phase out interferences, the Patent Trial and Appeal Board continues to declare and administer them where at least one of the parties has an interfering application or patent predating the AIA’s enactment. The Board declares interferences to avoid the embarrassment and marketplace chaos where the Patent Office issues two patents on the same invention to different parties, and to avoid awarding a patent monopoly to the entity who was not the first to invent.

In Shoes by Firebug LLC, v. Stride Rite Children’s Group, LLC, Appeals 2019-1622, and 2019-1623 (Fed. Cir. June 25, 2020), the Federal Circuit affirmed the PTAB’s IPR decisions that the claims of two challenged Firebug patents, directed to illumination systems for footwear, were unpatentable for obviousness. Although the PTAB erred in determining that the word “textile” in the preamble of both patents was not limiting (the term was limiting in one of the patents), the court concluded that this error did not affect the PTAB’s conclusions that all challenged claims were obvious.

In a recent precedential decision, the Federal Circuit affirmed a Patent Trial and Appeal Board decision, upholding an examiner’s final rejection of claims to a fishing method as unpatentable under 35 U.S.C. § 101.  In re Rudy, Case 2019-2301, Slip Op. (Fed. Cir. Apr. 24, 2020).  Appeals to both the Board and the Federal Circuit were cast by a pro se applicant, who is also a patent attorney.

The Patent Trial and Appeal Board designated as precedential two opinions with opposite outcomes on the issue of discretionary denial of inter partes review (IPR) petitions under 35 U.S.C. §314(a) in July.  In Apple Inc. v. Fintiv, Inc., IPR2020-00019, Paper 15 (May 13, 2020), the Board denied institution of an IPR due to a parallel district court proceeding in the Western District of Texas, whereas in Sand Revolution II, LLC v. Continental Intermodal Group-Trucking LLC, IPR2019-01393, Paper 24 (June 16, 2020), the Board instituted an IPR despite a parallel district court proceeding also occurring in the Western District of Texas.

A decision to stay patent infringement litigation falls within a federal court’s power to control its docket. But in determining whether to stay litigation pending the Patent Office’s inter partes review (IPR) of the patent, courts still are guided by three factors: (1) whether the stay will simplify the litigation, (2) whether a stay would unduly prejudice (or present a clear tactical disadvantage to) the patent owner, and (3) whether the litigation has progressed to some advanced stage (e.g., discovery is complete, a trial date is set, etc.). Yet since the Supreme Court’s 2018 decision in SAS Institute Inc. v. Iancu, 138 S. Ct. 1348 (2018) (discussed here), courts in the Eastern District of Texas have erected an unnecessarily high bar for stay-movants to leap.

In Fitbit, Inc. v. Valencell, Inc., Appeal 2019-1048 (Fed. Cir. July 8, 2020), the Federal Circuit determined that Fitbit, who had successfully sought joinder in an IPR petition filed by Apple, had standing to appeal an adverse determination as to certain patent claims, despite Fitbit’s failure to join that portion of Apple’s Petition. The Federal Circuit went on to rule that the PTAB had erred in rejecting Apple’s arguments as to those claim, and remanded the matter to the Board for further review.

In Telefonaktiebolaget LM Ericsson, (“Ericsson”), v TCL Corporation, (“TCL”), 2017-2381, -2385 (Fed. Cir. Nov. 7, 2019), the Federal Circuit affirmed the PTAB’s decision that canceled claims in an Ericsson patent that TCL challenged based on its subsidiary finding that a German journal article TCL presented was indeed prior art.  The decision is important because it offers guidance in assessing what type of evidence may be persuasive in a PTAB’s assessment of the public accessibility of a journal article whose publication date is close to the challenged patent’s critical date.

Back in 1988, the Federal Circuit reversed a district court decision that refused to award a party its reasonable attorney’s fees incurred in successfully litigating a patent’s validity before the Patent Office. PPG Indus., Inc. v. Celanese Polymer Specialties Co., 840 F.2d 1565 (Fed. Cir. 1988). The Office determined that the patent asserted in litigation—stayed pending the Office’s review—was invalid and obtained through inequitable conduct. Nobody contested the district court’s conclusion that the case was exceptional.
