The Proof Is In The Priority: Director Squires Addresses Antedating And Prior-Art Qualification
Director Squires issued written opinions in two recent PTAB proceedings examining critical threshold questions about prior art qualification. One case explored whether sufficient evidence supported an earlier invention date to antedate prior art, while the other determined if a reference was publicly accessible before the patent's priority date.

Navigating The Legal Safety Net Of NIST’s Post-Quantum Cryptography Patent Licenses
The global migration to post-quantum cryptography is actively underway following NIST's release of finalized standards for quantum-resistant algorithms. For general counsel and IP attorneys, intellectual property concerns present significant challenges when transitioning to new cryptographic standards, particularly regarding third-party patent claims on algorithms like CRYSTALS-Kyber (ML-KEM).

What Is Prior Art? Navigating Section 102, Case Law, And AI
Under the America Invents Act, what qualifies as prior art is measured against a claimed invention’s effective filing date. 35 U.S.C. § 102(a)(1) encompasses inventions “patented, described in a printed publication, or in public use, on sale, or otherwise available to the public” before that date, and § 102(a)(2) adds U.S. patents and published applications that name another inventor and were effectively filed earlier.

G 1/25: Enlarged Board Of Appeal Rules On Amendment Of The Description
The Enlarged Board of Appeal has issued a landmark decision in case G 1/25 addressing whether European patent descriptions must be amended to align with claim amendments during prosecution and opposition proceedings. This decision establishes a new two-part test for determining when description adaptation is required, potentially relaxing the EPO's historically strict approach to formal concordance between claims and descriptions.

USPTO Plans For AI Implementation
While this blog normally writes about the issues facing the patentability of AI inventions, we want to write about a topic that is high on our radar: the USPTO’s plans for integrating AI into the examination process. While certain programs, such as the USPTO’s Artificial Intelligence Search Automated Pilot Program (ASAP!) program were previously tested, a greater question looms on the availability of examiners to use large language models (LLMs) as a tool for examination.

Federal Circuit Confirms § 112(a) Support Required For A Reference’s Provisional Prior-Art Date
The Federal Circuit's decision in Dental Monitoring SAS v. Align Technology, Inc. establishes that a published patent application can only claim its provisional's filing date as prior art if the provisional provides written description support under § 112(a) for at least one claim. This ruling overturns the PTAB's more lenient "ministerial" standard and creates significant implications for both patent prosecution and inter partes review proceedings.
