1 case as defendant.
AT&T Inc. is a publicly-traded multinational telecommunications conglomerate headquartered in Dallas, Texas. The modern iteration of the company was formed in 1983 as Southwestern Bell Corporation, which later acquired its former parent AT&T Corporation in 2005 and adopted its name. Trading on the NYSE under the ticker "T", AT&T reported revenue of approximately $125.65 billion with around 133,030 employees for the fiscal year 2025.
AT&T is a major operating company providing a wide range of telecommunications and technology services. Its largest business segment is wireless services, making it the third-largest carrier in the United States, serving millions of postpaid and prepaid customers. Other significant operations include providing residential broadband internet through its AT&T Fiber network, which is the largest in the U.S. The company also offers fixed-line enterprise services such as internet access, private networking, and security, and maintains a wireless presence in Mexico. Subsidiary brands include Cricket Wireless.
Based on the provided data, AT&T Inc. is an operating company that defends itself against patent infringement lawsuits. It has been a defendant in all five tracked cases and has not been a plaintiff, a litigation posture typical for a large technology corporation. The lawsuits have been filed in venues known for patent litigation, including the Eastern and Western Districts of Texas and the District of Delaware.
The plaintiffs in the tracked cases appear to be patent assertion entities (PAEs). For example, Fleet Connect Solutions LLC is described as a non-practicing entity (NPE) and an entity of Empire IP, a monetization firm. Orthosie Systems, LLC has also been identified in public reports as an NPE asserting patents related to vehicle monitoring. AlmondNet, Inc. is an ad-tech company that actively litigates its patents, having won a significant verdict against Amazon. Portus Singapore Pte Ltd. has also filed numerous patent infringement lawsuits against various technology companies. These cases suggest that AT&T is primarily targeted by entities seeking to license or litigate patents related to technologies used in its extensive operations.
This case was one of three patents asserted against AT&T related to mobile data management. The case was dismissed without prejudice on September 29, 2025, following a joint stipulation of dismissal, which often indicates a settlement.
