Cobblestone Wireless LLC

Cobblestone Wireless LLC is a non-practicing entity (NPE) and an entity of Bedrock IP Co., Ltd.. The company is organized under the laws of Texas, with its address listed as 101 E. Park Blvd., Suite 600, Plano, Texas 75074. It was originally formed in Delaware and converted to a Texas LLC in October 2022. Jay Chung, who also manages other Texas entities like Redstone Logics and Sandstone Innovation, LLC, manages Cobblestone Wireless LLC.

As an NPE, Cobblestone Wireless LLC does not manufacture products or offer services, but instead asserts a portfolio of acquired patents. The patents asserted by Cobblestone Wireless LLC relate broadly to wireless communication systems. Specific patents include U.S. Patent 7,924,802, concerning wireless communication systems that transmit signals simultaneously over a communication channel at different RF center frequencies, and patents covering "User-Focusing Technique for Wireless Communication Systems" (U.S. Patent No. 8,891,347), "Wireless Device Handoff Between Wireless Networks" (U.S. Patent No. 9,094,888), "Adaptive Communication Resource Allocation in a Wireless Network" (U.S. Patent No. 10,368,361), and "Network Coverage By Cycling Through Beam Shape Coverage Configurations" (U.S. Patent No. 8,554,196). These patents were acquired from Empire Technology Development LLC.

The company's patent litigation posture is that of an NPE asserting an acquired portfolio. The provided case data shows three appearances as a plaintiff and zero as a defendant. Broader search results confirm numerous plaintiff-side lawsuits against major technology and wireless carriers, including T-Mobile USA, Inc., Apple Inc., and Samsung Electronics America, Inc. et al.. These cases are predominantly filed in jurisdictions known for being favorable to patent plaintiffs, such as the Eastern District of Texas and the Western District of Texas.

A notable aspect of Cobblestone Wireless LLC's litigation is the ex parte reexamination proceeding initiated by Unified Patents against U.S. Patent 7,924,802. Unified Patents' request was granted, indicating that substantial new questions of patentability were found regarding claims of the '802 patent. The company has asserted patents against a wide range of defendants including AT&T, Verizon, Cisco, HP Enterprises, CommScope, and Motorola Mobility (Lenovo).
