The well-positioned patent team of this European IP boutique owes its current visibility in the French market to the two SEP suits for NPEs Intellectual Ventures and IPCom. Frontman Julien Fréneaux has a good reputation for his experience in extensive telecoms cases. However, the series of proceedings for Intellectual Ventures, currently the largest in the telecoms sector, is tying up considerable capacities in the small French team, meaning that it is hardly appearing in other cases at all. There is no denying the firm’s dependency on these pr...
