The Chaos of Too Many Rules
The Patent Office issued Honeywell a patent that required correction. The patent, according to Honeywell, did not include the proper claim for the benefit of priority to the filing date of an application that Honeywell had earlier filed. But before Honeywell noticed the error and tried to correct that priority claim, its competitor, Arkema, petitioned the Patent Trial and Appeal Board to institute a post grant review proceeding. Shortly after institution, Honeywell sought the Board’s authorization to file a motion for leave to obtain from the Patent Office’s Director a certificate of correction. After all, the Director often issues certificates to correct priority claims. But the Board refused authorization and ultimately canceled the patent. On appeal, the Federal Circuit vacated the Board’s decision, chastising the Board for abusing its discretion. Honeywell Int’l Inc. v. Arkema Inc., Appeals 2018-1151, ‑1153 (Fed. Cir. Oct. 1, 2019).Continue Reading The Chaos of Too Many Rules
Federal Circuit Affirms Obviousness Decision by Board, No Violation
In Smith & Nephew, Inc. v. Arthrocare Corp., Appeal No. IPR2016-00918 (Fed. Cir. Aug. 21, 2019), the Federal Circuit affirmed the Patent Trial and Appeal Board’s decision in an IPR to invalidate patent claims on the basis of obviousness, determining that the Board did not violate the Administrative Procedure Act (APA) by describing the motivation to combine the teachings of the prior art in different language than that used in the petition. Additionally, the court affirmed the Board’s claim construction as reasonable and found that subjecting a pre-AIA patent to inter partes review was constitutional when the patent issued after the passage of the AIA.

A Reference is Publicly Accessible if a Person of Ordinary Skill in the Art Could Access the Reference
In a recent decision vacating the PTAB’s finding that a draft standard for video coding emailed to a listserv was not publicly accessible, the Federal Circuit again corrected the PTAB’s application of the legal standard to determine the public accessibility of prior art. Samsung Electronics Co., Ltd. v. Infobridge Pte. Ltd., case no. 2018-2007, 2018-2012, 2019 WL 3047113 (Fed. Cir. July 12, 2019).

Is the Written Description Requirement a Nose of Wax?
In re Global IP Holdings LLC, Appeal 2018-1426 (Fed. Cir. July 5,2019), concerns patent law’s written description requirement, under 35 USC § 112.

Four Decisions to Know regarding the PTAB’s Treatment of the new 2019 Patent Eligibility Guidelines
PTABWatch Takeaway: The Patent Trial and Appeal Board (PTAB) designated as “informative” four decisions applying the Patent Office’s 2019 patent eligibility guidance (PEG) regarding 35 U.S.C. § 101.

PTAB Precedential Decisions on Discretion to Institute Inter Partes Review
In May 2019, the PTAB designated precedential two IPR decisions related to its discretion to institute inter partes review.
In Valve Corp. v.
