District Court The Hague, 22 December 2010, 354781 / HA ZA 09-4290, Mbrands B.V. versus Handelsonderneming Kubus B.V.
This dispute concerns Kubus' Dutch patent for a trapeze belt hook device, to be used for water sports. MBrands sells trapeze belts and claims the invalidity of the patent. The MBrand products are marked "Patent Pend. Nr. 1035314", although this application has already been cancelled. Kubus therefore counterclaims, arguing that the patent marking on the Mbrands products is misleading.
