The UK Supreme Court today issued a landmark judgment on AI patentability that is likely to impact all software patents going forward. The decision in Emotional Perception v. Comptroller General of Patents, Designs and Trade Marks primarily held that the approach taken in Aerotel Ltd v Telco Holdings Ltd [2006] EWCA Civ 1371; [2007] Bus LR 634; [2007] RPC 7 (Aerotel) should no longer be followed. Under Aerotel, courts and examiners consider a four-step test for assessing whether a claim is excluded from patent eligibility: 1) properly construe the claim, 2) Identify the actual/ alleged contribution, 3) Ask whether the contribution is excluded and 4) check if the contribution is technical.

On Tuesday, news reports indicated that U.S. Senators Adam Schiff (D-CA) and John Curtis (R-UT) introduced the Copyright Labeling and Ethical AI Reporting (CLEAR) Act into Congress. If enacted as drafted, the bill would establish mandatory reporting requirements for companies developing artificial intelligence (AI) models that are trained using original works that are protected under U.S. copyright law, and would create an additional cause of action for copyright owners alleging that generative AI developers failed to give such notice with respect to their works.

This week on IPWatchdog Unleashed we discuss whether patent owners are better off facing post-grant challenges at the Patent Trial and Appeal Board (PTAB) or the Central Reexamination Unit (CRU) at the United States Patent and Trademark Office (USPTO). PTAB practitioners Matt Phillips and Kevin Greenleaf joined me for about how patent owners and challengers should be strategically thinking about the shifting post-grant environment at the USPTO. Our conversation highlights the growing reality that post-grant practice is no longer defined solely by inter partes review (IPR), but that ex parte reexamination has seen a resurgence in popularity, which requires careful evaluating timing, procedural dynamics, cost, and institutional realities. Fundamentally we attempt to answer the question of whether patent owners are better off in reexamination, or whether they are better off with IPR at the PTAB.
