    Nikon sues Viltrox over Z-mount patent infringement; patents at issue invalidated

    Nikon sued Viltrox in China, alleging that its Z-mount lenses infringed its patents. An affiliate of Viltrox filed invalidation requests, and the China National Intellectual Property Administration declared both Nikon patents at issue entirely invalid. Reports in July 2026 confirmed that Nikon lost its patent lawsuit against Viltrox in China; Nikon may still file an administrative lawsuit. Status: court judgment. Entities involved: Viltrox, Nikon. Scope: Z-mount lens products.
