LD Düsseldorf, September 2, 2026, Decision, UPC_CFI_297/2025, UPC_CFI_651/2025

1. Key takeaways

The Düsseldorf Local Division partially upheld the patent-in-suit, which relates to “SHARING MULTIMEDIA CONTENT IN A PEER-TO-PEER CONFIGURATION”, and found that the patent in its upheld version was indirectly infringed by the Disney+ streaming service. The decision focusses on claim construction, validity and some procedural aspects, applying the UPC’s established case law, for example regarding the inventive step test introduced in Meril v Edwards and Amgen v Sanofi.

Auxiliary requests are to be reviewed in the order secified by the Claimant, and dependent claims can be defended even without filing an auxiliary request under Rule 30 RoP (Application to amend the patent); cf. UPC_CoA_473/2025.
