JUVE Comment

This patent attorney team has only been operating in this setup for two years and is already one of the most active in patent litigation before German courts, especially when it comes to mobile communications and electrical engineering patents. The two name-partners Karl-Ulrich Braun-Dullaeus and Friedrich Emmerling enjoy an excellent reputation in this field, partly for their litigation for two companies often taken to court by NPEs: Deutsche Telekom and Huawei. Both mobile communications giants, however, also work with other patent attorney firms. Nonetheless, Emmerling’s work in a dispute involving photovoltaic patents demonstrates just how firmly he sits in the saddle for Huawei. Thanks to its vast litigation experience involving standard essential patents, Continental, one of the central interveners for Daimler, has also hired the firm for the dispute with Nokia and Conversant over connected cars patents. Huawei was also represented as intervener in this dispute. The firm can be seen in a central battle in another sector, too: Braun-Dullaeus represented Philip Morris along with Hoyng ROKH Monegier in a global series of suits by BAT over e-cigarettes. A strong focus on patent litigation is what sets the firm clearly apart from competing patent attorney firms. Even fierce competitors such as Maikowski & Ninnemann or Cohausz & Florak are reliant on more extensive prosecution practices.
