Prinz & Partner – Germany 2020
This firm dominated by patent attorneys has a broad technical focus but is especially well established among auto companies. The firm conducts many proceedings for these, from EPO oppositions to infringement proceedings concerning traditional engineering and mechanics patents – the great strength of the patent attorneys. Suppliers Valeo and ZF/TRW are among long-time clients. Prinz & Partner also made an early appearance in a case involving connected cars patents for Texas Instruments as intervener for Audi/VW two years ago. The dispute has since been settled. The firm has so far been unable to repeat such success; other patent attorney firms like Cohausz & Florack or Samson & Partner have a clearer profile for mobile communications suits. But Prinz & Partner is building expertise in the telecommunications sector through prosecution work for ZTE. Electronics client Rohde & Schwarz is also developing in the direction of connected products, which harbours potential for Prinz & Partner in this field. The firm closed its Hamburg office in 2020, as the partner working here withdrew from the legal profession at the end of the year. The Munich partners have taken over his clients.
