JUVE Patent

Witte Weller & Partner – Germany 2020

JUVE Comment

The patent attorneys at this Stuttgart IP boutique frequently litigate for Mittelstand technology companies, predominantly medical product manufacturers like Karl Storz and Diazyme. Pharma and biotech litigation has become the firm’s hallmark over many years. Work here is increasingly shifting towards biotech patents, where WW&P currently works mainly for German and US universities. Visibility in pharma patents, on the other hand, has decreased, partly because the best-known partner, Hajo Otten, retired at the end of 2019. Although the firm built up new talent in good time, this is not yet visible in litigation. Witte Weller is praised for its prosecution in many technical areas. Work for industry giants like Mitsubishi Electric, Philips or Sony has resulted in a strong specialty in electronics patents. The patent attorneys are also far more active than others in the region for other international corporations like Boeing, for which it conducts much EPO opposition work.
