Huawei Technologies has turned to two familiar faces—including one who was previously adverse—in its patent throw-down with Verizon Communications.

Fish & Richardson and Caldwell, Cassady & Curry are separately representing the Chinese telecom giant in two suits alleging that its New York-based competitor is infringing Huawei router and fiber-optic communication technologies. Verizon has called the suits “a PR stunt” driven by Chinese-American tensions.
