On July 4, 2017, the Düsseldorf District Court ruled that WOFI Leuchten Wortmann & Filz GmbH, a subsidiary of Taiwan-based LED producer Everlight Electronics Co., Ltd., is infringing Nichia’s YAG phosphor patent EP 0 936 682 (DE 697 02 929). WOFI is a German-based maker of residential LED lighting.
The court (in docket number 4b O 132/16) ruled in favor of Nichia’s claims for permanent injunction and also rendered a judgement in favor of accounts and damages. Furthermore, the court endorsed Nichia’s claim calling for recall of the accused products from the commercial customers and destruction of the accused products that are owned or in possession of WOFI. The judgment is not final and can be appealed.
