Tridonic v CUPOWER & Anor (UPC_CFI_459/2023)

• Tridonic alleged that the defendants had infringed its patent concerning LED lighting by the sale of LED drivers in Germany and France. The defendants denied infringement and made an invalidity counterclaim, alleging lack of novelty and lack of inventive step.
• In relation to Tridonic's infringement claim, the Düsseldorf LD found that the attacked embodiment did not infringe the patent because it did not have the decoupling element as specified in claim 7. The court concluded that the capacitor used in the defendants' product did not fully separate the signal paths, which was necessary for the claimed decoupling function.
• As for the defendants' invalidity counterclaim, the Düsseldorf LD found that the patent claims 7 to 10 were both novel and involved an inventive step. The counterclaim was therefore dismissed.
