On May 6, 2026, the Local Division of Düsseldorf issued an order concerning the European Patent EP 2 983 864 B1. The patent, held by OTEC Präzisionsfinish GmbH, involves a method and apparatus for surface treatment of workpieces. The applicant requested an inspection of the respondent's machine, the ANCA EPX-SF, exhibited at the GrindingHub in Stuttgart, to secure evidence of suspected patent infringement. OTEC claims that the EPX-SF uses technology possibly infringing their patent, which involves rotating a workpiece with varying speeds relative to abrasive material. The respondent, ANCA Europe GmbH, denies any infringement. The order allows for an inspection at the trade fair, with detailed procedures outlined for the examination of the EPX-SF machine to potentially prove infringement.
