This Essen-based firm is one of the best known patent-attorney litigation teams in the country. Not not did they conduct a host of oppositions for core clients, but increasingly infringement cases as well. The team recently won an 18-year battle for its most important client Novoferm against Hörmann over electric garage doors. AH represented other clients such as ThyssenKrupp in oppositions before patent offices, without having filed the patents beforehand. In general, however, the firm advises predominantly German clients on technical protection rights. The partner-heavy outfit takes a cautious approach to growth.
