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.

In General Access Solutions, Ltd. v. Sprint Spectrum L.P., Case No. 19-1856 (Fed. Cir. May 11, 2020) (non-precedential), General Access Solutions (“GAS”) appealed from two final written decisions of the Patent Trial and Appeal Board (“the Board”) in an inter partes review (“IPR”) proceeding holding that multiple claims of U.S. Patent Nos. 7,173,916 and 6,891,810 were obvious over prior art cited by Sprint Spectrum L.P. (“Sprint”). Specifically, the Board found certain claims to be unpatentable based on various grounds relying on U.S. Patent No. 7,366,133 (“Ahy”) as prior art under 35 U.S.C. § 102(e).

In a decision issued on May 5, 2020, the Federal Circuit reversed a PTAB decision upholding patent claims challenged for obviousness. Uber Technologies, Inc. v. X One, Inc., 957 F.3d 1334 (Fed. Cir. 2020). The Board failed to properly apply the obviousness test of KSR International Co. v. Teleflex Inc., 550 U.S. 398, 421 (2007), which recognized that a person of skill in the art has good reason to pursue the use of a finite number of identified, predictable solutions to solve a problem.

In The Chamberlain Group, Inc. v. One World Techs., Inc., Case 18-2112 (Fed. Cir. Dec. 17, 2019), the Federal Circuit held the USPTO erred in determining that Chamberlain raised a new argument during the Board’s final hearing. There, Chamberlain argued that the prior art did not anticipate certain claims of the patent. The Federal Circuit explained that “Chamberlain was merely clarifying its earlier position” in response to One World’s reply brief and “not raising a new issue.” The Court, nevertheless, affirmed the Board’s decision canceling the challenged claims as anticipated by the prior art, noting that substantial evidence supported the finding.

The Federal Circuit, in Arthrex, concluded that the Patent and Trial Appeal Board’s Administrative Patent Judges were unconstitutionally appointed “principal” officers. The court therefore vacated the Board’s decision that canceled claims in an inter partes review and remanded so a new panel of APJs would re-decide the patentability of the claims. What happens, however, when the Board’s pre-Arthrex final written decision does not cancel—but rather upholds the patentability of—the challenged claims? Well, there’s an appeal for that.

Double arrowsIn Hologic, Inc. v. Minerva Surgical, Inc., Case 19-2054 (Fed. Cir. Apr. 22, 2020), the Federal Circuit held that an assignor of a patent may rely on a PTAB unpatentability decision as a defense in infringement litigation, although the equitable doctrine of “assignor estoppel” prevents the assignor from directly challenging validity in the litigation. In Additional Views, Judge Stoll suggests that the en banc court reconsider the issue of assignor estoppel, because the court’s precedent permits an assignor of a patent to “circumvent the doctrine of assignor estoppel by attacking the validity of a patent claim in the Patent Office.”

On April 20, 2020, the Supreme Court held that PTAB decisions instituting IPR are final and non-appealable and that the language of 35 U.S.C. § 314(d) “indicates that a party generally cannot contend on appeal that the agency should have refused “to institute an inter partes review.”  Thryv Inc. v. Click-To-Call Technologies LP, case number 18-916, 2020 WL 1906544 at *4, __S.Ct. __ (2020).

Adidas successfully petitioned the Patent Trial and Appeal Board in 2012 to review a Nike shoe patent. During that review, Nike filed a motion to amend the patent by canceling all claims and substituting four new claims. The Board canceled the patent claims and found the new claims unpatentable. Among other things, the Board said that Nike—the patent owner—did not establish the new claims were patentable over the prior art.

In ATI Technologies v. Iancu, 920 F.3d 1362 (Fed. Cir. 2019), the Federal Circuit reversed the PTAB’s decision that the Patent Owner had not presented sufficient evidence to swear behind several prior art references.  In doing so, the Federal Circuit reminded the PTAB, as well as practitioners alike, of the proper standard of proof for demonstrating the diligent reduction to practice of an earlier purported conception.
