Rosenberger Technologies, a member of the Germany-based Rosenberger Group, announced that in June 2021, it filed a patent lawsuit in Suzhou, China against CommScope entities located in China and United States for infringement of multiple Rosenberger technology patents concerning base station antenna design.
Based on evidence Rosenberger submitted of infringement, on July 8, 2021, the court ordered a search of CommScope’s research, development, and production facilities to enforce pre-litigation evidence preservation.
CommScope is headquartered in the United States and the majority of its base station antennas is manufactured outside the United States. The manufacturer's Suzhou, China facility is CommScope’s largest for research, development, and manufacturing of base station antennas. The antennas developed and manufactured there are shipped and sold worldwide, including to the United States and Europe.
Rosenberger said its lawsuit is intended to stop CommScope’s manufacture and distribution of base station antennas that infringe Rosenberger’s patents. A Rosenberger statement said the company "is determined to protect its intellectual properties. With heavy investments annually, Rosenberger’s R&D-centered growth strategy has given it one of the most complete 4G and 5G antenna product ranges in the industry," added the statement.
An international market leader in RF and fiber-optic technologies, Rosenberger added that its "investment in the research and development of base station antenna technology has resulted in a vast patent portfolio and made it one of the fastest growing telecommunications companies worldwide."
