The ruling was announced on February 11, 2026, reported by Law360 UK with attribution to journalist Alex Baldwin.

The ruling marks a pivotal step toward broader patent protection for AI-driven technologies in the UK, signaling a more favorable environment for AI-related patents.

The decision sends the case back to the UK Intellectual Property Office to assess whether the Emotion Perception AI system can be granted a patent, clarifying how hardware involvement affects software-based inventions.

Emotional Perception AI’s ANN-based system, designed to suggest media and organize files to elicit similar emotional responses, was approved on appeal after an initial 2022 IPO rejection.

EPAI’s system uses two ANNs—one analyzing human-described media and the other analyzing media characteristics—and their interaction is central to assessing technical contribution.

No detailed explanation of the court’s reasoning or criteria distinguishing this neural network from typical programs is provided in the excerpt.

The case history follows a long trajectory: IPO rejection in 2022, High Court reversal in 2023, Court of Appeal overturn in 2024, and now Supreme Court guidance for re-examination.

The Supreme Court panel emphasized separating questions of invention from novelty and inventive step in the decision.

The case is referred back to the UKIPO for examination under the new framework, marking the first application of the G1/19 intermediate step in the UK process.
