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. Continue Reading
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).
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 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.

In consolidated appeals of a trio of Board decisions canceling pre-AIA patents in inter partes reviews (IPR), the Federal Circuit held “that the retroactive application of IPR proceedings to pre-AIA patents is not an unconstitutional taking under the Fifth Amendment.” Celgene Corp. v. Peter, Appeals 2018-1167, -1168, -1169, Slip Op. at 3 (Fed. Cir. July 30, 2019). As we previously discussed (link), the Supreme Court’s decision in Oil States Energy Services, LLC v. Greene’s Energy Group, LLC, 138 S. Ct. 1365, 1379 (2018), left open this issue. The Board’s decisions on appeal pre-date Oil States and unsurprisingly, perhaps, Celgene did not therefore raise the issue before the Board. But Celgene and the Patent Office briefed this constitutional issue in the appeal and then addressed it at oral argument to the Federal Circuit’s satisfaction. In further view of the growing number of appeals raising this issue in the wake of Oil States, the court exercised its discretion to decide the issue. Continue Reading
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. Continue Reading
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. Continue Reading
The Federal Circuit recently issued a decision in In re Marco Guldenaar Holding B.V., ruling the claims at issue were directed to the abstract idea of rules for playing a dice game. Finding that the recited elements did not amount to significantly more than that abstract idea itself, the court found the claims ineligible for patent protection. Continue Reading
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. The patentee is trying to reissue its patent on a carpeted load floor of a car. The patented floor includes thermoplastic components. The components, according to the patentee, ought not have been limited to thermoplastics, rather each should have been any plastic. So, the patentee sought to reissue the patent with a claim to the broader invention. The Patent Office examiner rejected the revised claim. Continue Reading
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. While the decisions are not binding on future PTAB panels, the decisions provide useful insights into how the PTAB may approach issues of patent eligibility on ex parte appeal, and what type of claims are likely to be found patent-eligible.
An overview of the PEG, including a description of how to analyze abstract ideas under the Patent Office’s newly revised step 2A, may be found in our previous posting titled How the PTAB Reviews Software Inventions Under the 2019 Revised Subject Matter Eligibility Guidance. Continue Reading
