In terms of patent litigation, Yealink Network Technology Co., Ltd. appears as a defendant in the single tracked case, indicating its posture as an operating company defending against patent assertions rather than an NPE. This sole tracked case is in the U.S. District Court for the Eastern District of Texas, a venue known for a high volume of patent litigation.
The company's notable legal involvement is the case of Barco, Inc. et al. v. Yealink (USA) Network Technology Co., Ltd. et al., filed in November 2023. In December 2025, Barco announced that Yealink had admitted to infringing six of its ClickShare patents related to wireless presentation technology. A jury in the U.S. District Court in Marshall, Texas, awarded Barco over $900,000 USD in damages for one year of infringing sales, leading to the removal of Yealink's WPP20 and WPP30 devices from the U.S. market. Yealink had previously suspended U.S. sales and recalled WPP30 Presentation Pod products in April 2024 in response to the lawsuit.
