    Summary: Court of Appeal decision (Panel 3, 16 Sep 2026) in Heraeus Electronics v Vibrantz (EP 3 215 288, metal sintering preparation), on appeals against the Munich Local Division decision of 10 Oct 2025 (UPC_CFI_114/2024, UPC_CFI_448/2024): both appeals are dismissed. In Heraeus's appeal on the infringement action, the first-instance dismissal stands: Vibrantz holds a prior-use right in Germany, and lawful German use cannot found a risk of infringement in France, Italy or Romania. Heraeus bears the costs of this appeal; value EUR 1,000,000.
