JUVE Patent

Olbricht Buchhold Keulertz – Germany 2021

JUVE Comment

With its Frankfurt and Hamburg partners, this well-positioned patent attorney firm enjoys a strong reputation for litigation work. This includes not only EPO suits, but also a whole host of nullity suits and infringement proceedings. Examples include litigation for Eurotronic concerning sensor technology for buildings, OWIM regarding shoe soles and P&M Services over paper cutting machines. The patent attorneys always conduct infringement proceedings alongside law firms like Arnold & Ruess.

Such proceedings often arise from prosecution work across a wide technical spectrum for numerous regular clients strong in the technological sectors, such as Edelmann Technologies and Norma. Mechanics and mechanical engineering are focal points here. The patent attorneys are occasionally in action in cross-border cases, such as those for a manufacturer of automation technology. But this is the exception – as a rule they litigate for technologically strong German Mittelstand companies in German proceedings and before the EPO.
