CommScope Sues SOLiD in Germany for Patent Infringement on its Digital DAS Innovations

CommScope has filed an additional patent infringement lawsuit in Germany against SOLiD, a manufacturer of Distributed Antenna Systems (DAS) based in South Korea. The complaint asserts German part of European Patent No. EP 2290850B1 relating to CommScope’s digital DAS innovations against SOLiD's Genesis DAS product line. CommScope asserted the United Kingdom part of this patent against SOLiD’s Genesis DAS product in the UK last year.

CommScope also enforced the U.S. counterparts of EP 2290850B1 in separate US patent infringement actions against Dali Wireless and SOLiD. The US action against SOLiD was filed in May of 2020 and, after noting that SOLiD withdrew its Genesis DAS product from the US market, CommScope voluntarily dismissed that action.

“CommScope has invested heavily in innovation in the field of digital distributed antenna systems to benefit its customers and reinforce its position as a global leader in wireless and wireline network infrastructure. This leadership was recognized when Kathrein took a royalty-bearing license to CommScope’s digital DAS patents in 2017 and again in the 2019 U.S. case against Dali with a jury finding CommScope’s patents valid and that Dali willfully infringed. We continue to vigorously protect these valuable assets, and this additional action against SOLiD is a necessary step to prevent unauthorized infringement,” said Matt Melester, Chief Technology Officer, Venue & Campus Networks, CommScope.

The new German action was filed December 18, 2020 in the Munich District Court. The German part of EP 2290850B1 is subject matter of nullity proceedings pending with the Federal Patent Court [docket #4 Ni 7/20 (EP)]. The pending action before the UK Patents Court is Claim #HP-2020-0017 and asserts both EP 2290850B1 and EP 1570626B1.
