JUVE Comment

The patent attorneys at this German IP litigation boutique have earned an outstanding reputation for their work in complex mobile communications proceedings, including EPO oppositions. The team led by Karl-Ulrich Braun-Dullaeus and Friedrich Emmerling ranks among the market leaders in this clearly defined specialty, particularly regarding SEPs.

The team has built this reputation primarily through representing long-standing client Huawei in numerous substantial patent battles. This work has established the firm’s strong reputation among Chinese companies, leading to new clients in this sector. These new clients primarily operate in emerging technical fields that work with electronic patents outside mobile communications, such as solar technology and automated systems.

While the firm maintains a small prosecution practice, this holds declining strategic importance as the team focuses increasingly on litigation and EPO oppositions, no longer considering patent filing as essential to its core business.

European set-up

Braun-Dullaeus Pannen Emmerling maintains consistent involvement in UPC proceedings, initially through its long-standing client Huawei. The team is well positioned for future UPC litigation concerning electronic patents, particularly SEPs.

Although the firm must compete with numerous mixed teams, this presents no novel challenge for Braun-Dullaeus Pannen Emmerling. For instance, it currently collaborates with mixed law firm Bird & Bird in representing Huawei in litigation against Amazon.

Strengths

Litigation, mainly concerning mobile communications and electronics patents.
