USPTO Director Ends IPR Against Midas Green Technologies

Jul 27 2025

On 25 July 2025, K&L Gates secured an important win for its client, Midas Green Technologies, LLC. Acting USPTO Director Coke Morgan Stewart granted Director review and denied institution of an inter partes review (IPR) petition filed by Midas Green’s competitor, Green Revolution Cooling, Inc., which had sought to invalidate U.S. Patent No. 10,405,457—currently being asserted by Midas Green in a parallel lawsuit pending in the Western District of Texas. The patent describes a modular immersion cooling system that circulates dielectric fluid to cool vertically mounted electronic appliances, such as computer servers, in a tank.

Jul 23 2025

Effective 1 September 2025, all hearings before the Patent Trial and Appeal Board (PTAB) will be conducted in person.

First Denial Based on USPTO’s New Discretionary Denial Factors

Jun 13 2025

Earlier this year, Chief Judge Boalick issued guidance on the USPTO’s recission of “Interim Procedure for Discretionary Denials in AIA Post-Grant Proceedings with Parallel District Court Litigation,” explaining how the Fintiv factors should be addressed going forward. Shortly after, Acting Director Stewart issued a memorandum titled “Interim Processes for PTAB Workload Management” that provided additional non-Fintiv discretionary factors that should be assessed to determine whether discretionary denial of an IPR petition is appropriate.

Federal Circuit Clarifies Scope of Estoppel Provision and Provides Guidance on “Patentably Distinct” Claims

Jul 30 2024

On 26 July 2024, the Federal Circuit entered its decision in SoftView LLC, v. Apple Inc.¹ holding that patent owner estoppel² applies to newly presented and amended claims, but does not apply to issued claims. The Federal Circuit also confirmed that patent owner estoppel prevents a patent applicant from later obtaining a patent claim that is “not patentably distinct” from a finally refused or cancelled claim, but that patent owner estoppel does not apply to defending issued, unamended claims.

Federal Circuit Rules AAPA in Challenged Patent Does Not Qualify as Prior Art Under 35 U.S.C § 311(b) but Signals AAPA Can Play Role in §103 Analysis

Feb 03 2022

On 1 February 2022, the Federal Circuit released its decision in Qualcomm v. Apple¹ providing guidance on the treatment of Applicant Admitted Prior Art (AAPA) under 35 U.S.C § 311(b) in Inter Partes Review (IPR) proceedings. In doing so, the Federal Circuit vacated two IPR decisions² of the Patent Trial and Appeal Board (PTAB) where the PTAB had found several claims of U.S. Patent No. 8,063,674 (“the ’674 patent”) unpatentable under 35 U.S.C. § 103. In doing so, the Federal Circuit remanded the case to allow the PTAB to address the specific issue of whether the AAPA cited by Apple improperly formed the “basis” of Apple’s § 103 challenge or was simply ancillary.

French Reform of Automatic Intellectual Property Assignment for Non-Employee Personnel

Jan 10 2022

France is widely known for its author-centric intellectual property right (IPR) framework: except for a limited number of very specific situations, all IPR must be expressly assigned and there is no “work for hire” doctrine.

This situation is changing, further to Decree n°2021-1658 dated 15 December 2021, replicating the regime applicable to inventions and software created by employees or public servants to those made by natural persons accommodated by private or public law entities carrying out research.

This decree amended the French Intellectual Property Code (FIPC), by creating two new articles: L.113-9-1 (with regard to software IPR) and L.611-7-1 (with regard to patent IPR) FIPC.

Substance Over Form: The Importance of Substantive Grounds in Parallel District-Court Litigation and Prior Petition IPR Denials in OpenSky Indus., LLC v. VLSI Tech. LLC

Jan 09 2022

On 23 December 2021, the Patent Trial and Appeal Board (“the Board”) instituted inter partes review (IPR) of U.S. Patent No. 7,725,759 B2 (“the ’759 patent”). See OpenSky Indus., LLC v. VLSI Tech. LLC IPR2021-01064, Paper 17 (Dec. 23, 2021). Petitioner OpenSky Industries, LLC (“OpenSky”) relied on expert declarations of Dr. Sylvia D. Hall-Ellis and Dr. Bruce Jacob originally filed by Intel Corporation in two other IPR proceedings (“Intel IPRs”).¹ Indeed, the declaration included the same coversheet that accompanied the declaration in the Intel IPR. The Board analyzed OpenSky’s Petition under §314(d) and §325(d), declining to deny institution, finding, in part, that since Fintiv and General Plastic did not warrant discretionary denial, the arguments, which were almost identical to those made in the Intel IPRs, deserved to see their day in court at the PTAB.

PTAB’s Motion to Amend Patentability Powers

Jul 27 2020

In a 2-1 split decision on Wednesday, July 22, 2020, the Federal Circuit confirmed that the Patent Trial and Appeal Board (“PTAB“) had the authority to reject substitute claims under 35 U.S.C. §§ 101 and 112, statutory grounds not available to the PTAB for evaluating patentability of granted patent claims in inter partes review (“IPR“). (Uniloc 2017 LLC, v. Hulu, LLC et al., Case No. 2019-1686, slip op. at 3 (Fed. Cir. July 22, 2020).)

PTAB designates additional decisions precedential relating to its discretion to deny petitions

Mar 26 2020

On Tuesday, the Patent Trial and Appeal Board (PTAB) designated two decisions precedential and one as informative explaining the circumstances under which the Board will exercise its discretion under 35 U.S.C. § 325(d) and 35 U.S.C. § 314(a) to deny petitions. The cases analyzed situations where the prior art and invalidity arguments advanced by Petitioner were similar/identical to those previously considered by the examiner and where the timing of a final decision may coincide with another body’s findings (e.g., a district court trial) regarding validity. These cases provide guidance to Petitioners and Patent Owners alike about how to construct discretionary denial arguments, in particular regarding the appropriate way to address art that may or may not be cumulative to already-considered references.
