UK’s AI Patent Reset. The success condition here isn't “more AI patents.” It’s: clearer, more consistent identification of technical contribution...
Summary
On February 11, 2026, the UK Supreme Court issued a landmark judgment in Emotional Perception AI Limited v Comptroller General of Patents, Designs and Trade Marks, significantly altering the assessment of AI and software patents in the UK. The Court effectively retired the "Aerotel" test, which focused on whether a contribution was technical, in favor of an approach more aligned with the European Patent Office (EPO) under the European Patent Convention. This new framework separates the question of whether something is an "invention" (requiring only "any hardware" as technical means) from the assessment of "inventive step," which now scrutinizes the technical contribution more sharply. The ruling means that while AI inventions, including artificial neural networks (ANNs), can still be considered "programs for computers," their patentability hinges on demonstrating genuine technical features and contributions, rather than merely achieving a desired outcome.
Key takeaway
For CTOs and entrepreneurs developing AI products, this UK patent shift means a potentially easier path through initial eligibility, but significantly increased scrutiny on the actual technical contribution of your invention. You must clearly articulate and document how your AI solves a technical problem with specific technical features, rather than just claiming improved outcomes. This requires a shift in patent strategy, emphasizing engineering details and system performance improvements to secure defensible patents and mitigate future litigation risks.
Key insights
The UK Supreme Court realigned AI/software patentability with EPO standards, separating invention eligibility from inventive step.
Principles
- "Any hardware" can satisfy invention eligibility.
- Technical contribution drives inventive step.
- UK patent practice now aligns with EPO Article 52.
Method
The new patent assessment involves a low-hurdle eligibility check for "technical means," an intermediate filter for technical features, and then novelty/inventive step assessment based on those technical contributions.
In practice
- Document measurable compute/memory gains.
- Design claims around explicit technical mechanisms.
- Conduct proactive freedom-to-operate scanning.
