Untitled case

Competitive Access Systems, Inc. (CAS), identified as a Non-Practicing Entity (NPE), has initiated a patent infringement lawsuit against Samsung Electronics Co., LTD., Samsung Electronics America, Inc., and Samsung Research America (collectively, "Samsung"). CAS, a Texas-incorporated entity based in Plano, Texas, was founded by Eric Delangis, who has a background in designing communication systems. The defendants, comprising South Korean-based Samsung Electronics Co., Ltd., its New York-based subsidiary Samsung Electronics America, Inc., and California-based Samsung Research America, are global operating companies known for their consumer electronics, including smartphones and cellular network infrastructure. The plaintiff alleges that Samsung's consumer electronic products, particularly its Galaxy Smartphones, infringe on CAS's patents by implementing 3GPP standards in conjunction with the devices' simultaneous use of 4G LTE and 5G connections.

The core of the dispute involves U.S. Patent No. 8,861,349, among others (9,350,649; 11,418,641; 11,582,343; 8,228,801; and 10,868,908). U.S. Patent No. 8,861,349, titled "System and method for aggregating network bandwidth," describes a technology designed to improve internet connection speeds by aggregating multiple internet connections. This allows for a combined bandwidth that is greater than that of any single connection.

The case, numbered 4:25-cv-00886, was filed on August 15, 2025, in the Sherman Division of the U.S. District Court for the Eastern District of Texas. The assigned judge for this specific case is not publicly available from the current search results. The Eastern District of Texas is a prominent venue for patent litigation, particularly favored by plaintiffs and NPEs due to its historically plaintiff-friendly procedural rules, accelerated trial schedules, and a reputation for higher plaintiff success rates and damage awards. The district maintained its position as the top patent district for overall and NPE litigation in 2025. As of the current date, no Inter Partes Reviews (IPRs) specifically challenging U.S. Patent No. 8,861,349 have been found. The case is notable as it reflects a common pattern of NPEs asserting patents against major technology manufacturers in a jurisdiction known for its favorable environment for patent holders.
