On July 6, 2010, the German Federal Supreme Court of Justice (BGH) essentially upheld the German part of the European patent EP 0 781 629 B1 following a previous declaration of invalidity by the Federal Patent Court. No further appeal can be lodged against this decision of the BGH. The patent protects the Multiloch sanding disc technology developed by Jöst GmbH, which is marketed under the name "useit-Superpad P. The special feature of the "useit Superpad P" is that the sanding disc has many small perforations through which the sanding dust is extracted from the sanding surface by the shortest route. 1 BARDEHLE PAGENBERG Partnerschaft mbB, Abrasives manufacturer Jöst wins case before German Federal Supreme Court of Justice, July 23, 2010
