JUVE Patent

Witte Weller & Partner – Germany 2021

JUVE Comment

Although filing activity fluctuated in the first year of coronavirus, the well-positioned litigation practice of this Stuttgart IP boutique made steady progress. This is thanks to Witte Weller’s strong specialty in the life sciences sector. EPO oppositions, nullity suits and infringement proceedings are mainly conducted for Mittelstand companies from the medical product sector, such as Karl Storz and Diazyme. Work involving biotech patents is also taking on a weightier role, for instance for German and US universities and Jennewein Biotechnologie, which was recently taken over by Danish competitor Christian Hansen. This has so far not had a negative impact on Witte Weller’s activity. Pure pharma patents, on the other hand, are of somewhat less importance.

Because of the close cooperation with law firms, such as Gleiss Lutz, Witte Weller conducts infringement proceedings across a broad technical spectrum overall. It is battling for Sony over display devices for digital texts, for Supponor over advertising overlays on TV broadcasts and for Stihl over robot lawnmowers.

This technically broad focus is also reflected in prosecution work. The firm is busy conducting EPO oppositions for regular client Boeing, although its business came under extreme pressure during the coronavirus crisis. Work for other industry giants, such as Mitsubishi Electronics and Philips, bears witness to the firm’s experience with electronics patents.
