Vringo Infrastructure Inc., a wholly owned Vringo Inc. subsidiary, filed a patent-infringement lawsuit against the U.K. subsidiary of China’s ZTE Corporation. "The filing of this action in the United Kingdom is an initial step in Vringo’s global licensing and enforcement program in the telecommunications sector. ZTE has elected not to take a license to patents in Vringo’s portfolio relevant to certain international standards, despite manufacturing and selling devices and equipment for a number of years that are said by ZTE to be compliant with those standards," said David L. Cohen, who heads licensing, litigation and intellectual property at Vringo. "We believe that ZTE is aware that it requires licenses to all patents that are essential to relevant standards. Further, we believe that ZTE is familiar with systems for declaring patents to standards-setting organizations and the relevant intellectual property rights policies for those organizations, having itself declared hundreds of patents to international standards."
