ACT_14764/2025

Hamburg Local Division granted a preliminary injunction ordering OTEC Präzisionsfinish GmbH to cease and desist from manufacturing, offering, placing on the market, using, exporting, or possessing in 18 UPC contracting states an electrolytic medium for electropolishing processes that infringes a patent for such a medium. The court held that validity is established on a balance of probabilities standard (more likely than not valid); the burden for invalidity lies with the defendant. The weighing of interests favoured the applicant as the defendant's product enabled new machine sales creating market opportunities lost to the applicant. The defendant's request for security for enforcement was denied as no sufficient facts (e.g. financial difficulties) were presented. Penalty of up to EUR 250,000 per non-compliance.
