Munich, February 19, 2020: The fischerwerke GmbH & Co. KG, based in Waldachtal/Germany, has successfully defended European Patent EP 1 338 711 B1 for special fixings for sanitary ceramics in nullity appeal proceedings before the German Federal Supreme Court – BGH (Docket number: X ZR 6/18). By its judgment of 13 February 2020, the BGH set aside the judgment of the 7th Senate (Nullity Senate) of the German Federal Patent Court of 7 December 2017 (Docket number: 7 Ni 15/16 (EP)), by which the patent in suit at the initiative of the Spanish competitor Celo Fijaciones S.L. (formerly Apolo Fijaciones y Herramientas, S.L.), had been partially revoked.

With patent EP 1 338 711 B1, fischerwerke has protected an innovative solution in the field of special fixings for sanitary ceramics. These are used in particular for toilet bowls freely suspended on the wall, where considerable forces act on the fixing at an unfavorable angle under load. fischerwerke, the world market leader for plugs, also offers a wide range of innovative special fixings. A special feature in this case is that the fixing is completely retractable and thus does not impair the high-quality design of modern toilet bowls.

The patent for this innovative solution, which fischerwerke had applied for on 16 January 2003, was already successfully enforced against a major competitor before the Regional Court of Dusseldorf in 2015. Following these infringement proceedings, the Spanish competitor Apolo Fijaciones y Herramientas, S.L. (now Celo Fijaciones S.L.) filed a nullity suit against the patent because it wanted to launch its competing product on the German market. Parallel proceedings against this competitor are pending in Italy and Turkey.

In the opinion of the opposing party, the granted version of fischerwerke’s patent comprised added matter compared to the original application. On objection of the examiner during prosecution of the patent application, fischerwerke had amended independent claim 1 by including a feature from an embodiment described in a dependent claim without including all features of this embodiment. However, the BGH allows such a “generalization” if it is directly and unambiguously disclosed to the skilled person that the adopted feature as such promotes the solution of the problem to be solved by the patent irrespective of the other features. This case law, which was established, inter alia, in the well-known decisions “Kommunikationskanal” and “Stent”, has been fully confirmed by the BGH in the present decision.

The fischerwerke GmbH & Co. KG was represented in the proceedings by partner Dr. Constantin Kurtz of KLAKA Attorneys at Law and by patent attorney Dipl.-Ing. Dieter Späth, partner of ABACUS Patent Attorneys. Apolo Fijaciones y Herramientas, S.L. (today Celo Fijaciones S.L.) was represented by Dr. Felix Wolff and Dipl.-Phys. Jan Pieter Loock of Kutzenberger Wolff & Partner. Dr. Constantin Kurtz has been representing fischerwerke in patent disputes in Germany for many years.
