Untitled case

This patent infringement litigation, Case No. 4:25-cv-00886, was filed on August 15, 2025, in the U.S. District Court for the Eastern District of Texas, Sherman Division. The plaintiff is Competitive Access Systems, Inc. (CAS), identified as a Patent Assertion Entity (NPE). The defendants are Samsung Electronics Co., Ltd., Samsung Electronics America, Inc., and Samsung Research America, collectively referred to as Samsung, which are operating companies in the high-tech electronics industry, particularly known for their consumer electronic products like smartphones and network infrastructure. The case is assigned to District Judge Sean D. Jordan.

The core of the dispute revolves around U.S. Patent No. 11,418,641, titled "Devices and Methods for Multipath Communications". This patent generally relates to technologies that enable multipath communications, which allow devices to use multiple network connections simultaneously for improved data transfer and reliability. The complaint alleges that Samsung has infringed this patent through the making, using, selling, offering for sale, and/or importing of its products, including various Samsung Galaxy Smartphones and base stations. Specifically, the accused products are those that implement 3GPP standards, such as those employing E-UTRAN New Radio-Dual Connectivity (EN-DC) and Carrier Aggregation (CA) technology, which facilitate the simultaneous use of 4G LTE and 5G New Radio connections. Although the patent expired on December 11, 2023, CAS is seeking damages for alleged infringement that occurred prior to its expiration.

The Eastern District of Texas is a prominent venue for patent litigation, often chosen by plaintiffs due to its historically fast-paced dockets and patentee-friendly reputation, which can be advantageous for NPEs like CAS. This case is notable as a continued assertion by an NPE against a major technology company in the high-tech sector, targeting widely adopted wireless communication standards implemented in consumer devices. While the current search did not reveal specific IPRs directly linked to Patent 11,418,641 within the context of this particular lawsuit, Competitive Access Systems Inc. has been involved in other patent infringement cases and IPR proceedings.
