Based on a January 2026 webinar, various divisions of the Unified Patent Court (UPC) have issued pivotal rulings standardizing the assessment of inventive step. The Court of Appeal unified the system by establishing a refined three-step framework in Amgen v. Sanofi—permitting multiple realistic starting points and focusing on the expectation of success—while ruling in Meril v. Edwards that non-obvious alternatives qualify for protection without requiring a technical improvement.
This appellate standard resolved prior first-instance divergence, where the Munich Central (Sanofi v. Amgen) and Munich Local (Edwards v. Meril) divisions strictly adhered to the EPO’s problem-solution approach, while the Paris Central Division (Enjoy v. VMR) derived the objective problem solely from the patent itself. Lower courts immediately applied this framework in early 2026, with the Paris Local Division (IMC Creation v. Multi-Loc) executing an exhaustive analysis across five prior art combinations, and the Paris Central Division (Whitewater West v. American Wave) adopting a more streamlined, patent-focused application of the test.
