Since the Federal Circuit’s 2018 en banc decision in Wi-Fi One, LLC v. Broadcom Corporation, (discussed here) the court has reviewed a number of PTAB decisions on whether an IPR petition was filed more than one year after the petitioner was served with a complaint asserting the challenged patent, and thus time-barred under 35 U.S.C. § 315(b) (see here, here, here). But a patent owner’s time-bar challenge must be timely raised before the PTAB, and may be waived if raised for the first time on appeal.

In a case involving online gaming, the Federal Circuit affirmed the PTAB’s decision that 35 U.S.C. § 315(b) did not bar instituting an IPR where the patent owner failed to preserve its arguments that service was perfected. Game and Technology Co., Ltd. v. Wargaming Group Limited, ___ F.3d __, 2019 WL 6121449 (Fed. Cir. Nov. 19, 2019). However, the Court disagreed with the PTAB’s view that it “does not ‘have the authority…to deem service to have occurred and overlook errors in service’” where no district court has deemed service to have occurred.

In Arthrex Inc. v. Smith & Nephew, Inc., Appeal 2018-2140 (Fed. Cir. Oct. 31, 2019), the Federal Circuit concluded that the PTAB’s Administrative Patent Judges (APJs) are “principal” officers and their appointment by the Secretary of Commerce therefore violates the Constitution’s Appointments Clause. The issue arose in an appeal of a decision by a panel of APJs canceling claims in Arthrex’s patent in a recent inter partes review (IPR). But because that decision occurred while there was an Appointments Clause violation, the court vacated and remanded the IPR to be decided by a different panel of APJs.

The Patent Trial and Appeal Board (PTAB) recently published a second update to its Trial Practice Guide (TPG). The TPG, initially released in 2012, was first updated in August 2018 (see here). This second update further revises and/or adds guidance relating to certain general procedures and many aspects of trial practice before the PTAB.

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

In Henny Penny Corp. v. Frymaster LLC (Fed. Cir. 2019), the Federal Circuit again upheld the PTAB’s application of its rule prohibiting petitioners from raising new arguments in a reply brief, and upheld the challenged claims as not unpatentable for obviousness, relying in part on secondary considerations evidence.

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). Although multiple means of accessibility were alleged, the PTAB’s analysis was upheld with respect to all but the listserv distribution.

As we have discussed (here and here), owners of pre-AIA patents may be able to “swear behind” alleged prior art references by providing evidence of an earlier invention date, but the inventors’ testimony concerning conception of the invention must be corroborated by independent evidence. In Kolcraft Enterprises, Inc. v. Graco Children’s Products, Inc., No. 2018-1259 (Fed. Cir. Jul. 2, 2019), the patent owner was unable to swear behind alleged prior art because it did not provide sufficient corroborating evidence.

In an unusual fact situation, Judge Andrews of the U.S. District Court for the District of Delaware held that estoppel stemming from a Final Written Decision of the PTAB could arise even if issued after trial where the court has not yet entered final judgment on the relevant ground. Novartis Pharmaceuticals Corp. v. Par Pharmaceutical Inc., Case No. 14cv1289 (D. Del. April 11, 2019).

The nature of any inter partes dispute apparently is to engage in even a seemingly mundane dispute. After all, that’s the dispute that may lead you to success, right? Perhaps then there is nothing surprising in an April 3, 2019, Patent Trial and Appeal Board order concerned about whether a book qualifies as prior art. That order, issued by the Board’s new “Precedential Opinion Panel,” grants an aggrieved petitioner’s request for rehearing of an earlier Board decision refusing to institute inter partes review because the petitioner apparently did not establish a book bearing a 1990 (or 1991) copyright date was publicly available before the 1995 date on which the application for the subject patent was filed. Hulu, LLC v. Sound View Innovations, LLC, Case IPR2018-01039 (Apr. 1, 2019) (order).
