Braun-Dullaeus Pannen Emmerling – Germany 2022
This IP boutique from Düsseldorf and Munich is one of the most active litigation outfits on the patent attorney side before the German civil courts and EPO. With a strong market position, the team led by Karl-Ulrich Braun-Dullaeus and Friedrich Emmerling has an excellent reputation for litigation in complex mobile communications cases.
The firm’s experience in defending against SEP claims stands out. Continental, as a co-litigant of Ford, trusted the firm to defend it in a connected cars action by IP Bridge. One new client is Chinese semiconductor manufacturer Goodix, which is known for touch displays and which the firm defended against an attack by Wavetouch involving implementation patents.
The firm also litigates in other technological fields when high economic stakes are involved, for example the e-cigarette dispute for Philip Morris. The team operates a small prosecution practice and is looking to strategically build on this but is still called on much more frequently for its litigation strength.
Litigation, mainly over mobile communications patents on the implementer side.
The Braun-Dullaeus Pannen Emmerling team brings the experience needed to represent clients at the UPC in telecoms cases by joining forces for patent proceedings with law firms without patent attorneys of their own, like Freshfields Bruckhaus Deringer and Preu Bohlig & Partner. The firm is taking a strategic wait-and-see approach to the UPC, partly because its clients from China and the automotive industry expect to be put at a disadvantage by the new system. They have been sued many times lately, however, and it is likely that their opponents will use the new European court in future. This could also become an option for regular client Huawai if it wants to push through its strong 5G portfolio.
