Sponsored by Businesswire

CommScope, a global leader in infrastructure solutions for communications networks, announced today that CommScope Technologies LLC has filed a patent infringement lawsuit in the United States District Court for the District of Delaware against Rosenberger Site Solutions LLC and two related Chinese companies, Rosenberger Asia Pacific Electronic Co., Ltd. and Rosenberger Technology (Kunshan) Co. Ltd. (hereinafter “Rosenberger”).

In its complaint, CommScope asserts that certain cellular base station antennas manufactured in China by Rosenberger and sold in the United States, infringe seven of CommScope’s patents associated with CommScope’s base station antenna innovations. These CommScope patents relate to critical building blocks and enhanced methods used to design a wide array of base station antennas, commonly known as BSAs, that service frequency bands ranging from 600MHz to over 2000MHz. These key technologies enable CommScope’s customers to buildout high performance multi-band cellular networks. The asserted CommScope patents are U.S. Patent Nos. 7,358,922; 7,535,430; 9,698,486; 9,831,548; 10,439,285; 10,498,035; and 10,547,110.

This is the second lawsuit CommScope has filed against Rosenberger relating to its use of CommScope’s base station antenna technology. In July of 2019, CommScope filed suit against various Rosenberger entities and two former CommScope employees now employed by Rosenberger. In that lawsuit, CommScope asserts, among other things, misappropriation of trade secrets, including trade secrets relating to CommScope’s proprietary software programs and CommScope’s base station antenna hardware. That case remains pending in the United States District Court for the District of New Jersey.

“CommScope innovates, designs, manufactures, and sells best-in-class products and solutions around the world,” said Farid Firouzbakht, senior vice president and segment leader of Outdoor Wireless Networks for CommScope. “CommScope has taken this action to protect the company’s significant investments in developing innovative products that help our customers unlock the potential of their network infrastructure.”

The most recent action and complaint can be found at CommScope Technologies LLC v. Rosenberger Site Solutions, LLC et al., Action No. 1:20-cv-01053 (D. Del. August 2020).
