CommScope sues China's Comba Telecom for patent infringement

Infrastructure solutions provider for communications networks, CommScope, Inc, has filed patent infringement lawsuits in China and begun legal proceedings in Brazil against Comba Telecom Systems Holdings Ltd. and its affiliates.

Integrated wireless solutions and sub-system provider, Hong Kong-listed Comba  claims an over 25-per cent market share in China.

The legal move by CommScope, through its Andrew LLC subsidiary, focuses on Comba's alleged infringement of the company's patents related to its remote electrical tilt (RET) technology for base station antennas used in wireless networks.

CommScope says its patented RET system enables frequent and cost-effective beam adjustment of the variable electrical downtilt of base station antennas, improving the
coverage, capacity, and quality of cellular networks.

''CommScope's extensive portfolio of patents and intellectual property is the result of years of effort and considerable monetary investment in research and development,'' said Randy Crenshaw, executive vice president and chief operating officer, CommScope. ''These valuable intellectual property assets are a lifeblood of the company and core to the innovation we deliver to customers around the world. We have vigorously protected these valuable assets in the past and will continue to do so in the future.''

CommScope  said that it owns various patents around the world covering RET technology through its Andrew LLC subsidiary and would actively defend these rights.
