Wireless equipment maker Comba Telecom Systems Holdings wants a series of patent-infringement lawsuits filed against it in China and Brazil by CommScope to be quashed for lack of merit.
The legal actions initiated by privately held CommScope, through its Andrew LLC subsidiary, focused on Hong Kong-listed Comba's alleged infringement of the United States-based company's patents relating to its remote electrical tilt (RET) technology for base station antennas used in wireless networks.
In a filing with the Hong Kong stock exchange late on Friday, Comba said it was 'now in the process of undertaking effective measures in response to the allegations'.
Comba specialises in wirelessenhancement products, which include indoor and outdoor repeaters, tower-mounted boosters and remote radio units used by telecommunications network operators to cover blind spots in 2G, 3G and Wi-fi network coverage.
'The company has undertaken positive measures to safeguard its legal rights of operation and will not rule out the possibility of initiating counter-litigation against Andrew,' Comba executive director Wilson Tong Chak-wai said. While Tong insisted there would be no significant adverse impact on Comba's business, the litigation certainly could appear as a red flag to customers.
China Mobile, China Unicom and China Telecom accounted for 84.8 per cent of Comba's total revenue of HK$5.2 billion last year. Its antenna products are adopted for base stations made by Huawei Technologies, ZTE Corp, Nokia Siemens Networks, Ericsson and Alcatel-Lucent.
