SOLiD defeats patent infringement claims in U.S., UK, and Germany over DAS equipment for 5G technology

Client(s) SOLiD, Inc.

Jones Day successfully represented SOLiD, Inc. in multi-jurisdictional patent litigation proceedings brought by a competitor who alleged that client's leading Distributed Antenna System ("DAS") solutions infringe claims of six patents (two European and four U.S.). Digital DAS equipment has gained significant importance with the evolution of 5G wireless and a market shift from analog to digital DAS.  CommScope dismissed the U.S. litigation prior to SOLiD’s response to the complaint, after SOLiD proceeded to file five IPR petitions before the PTAB challenging CommScope’s patents.  The case in the United Kingdom proceeded to trial where SOLiD was fully successful, revoking one patent and having two others dismissed from the case.  CommScope subsequently withdrew its infringement proceedings in Germany.
