1 case as defendant.
AT&T Corp. is the long-distance subsidiary of its parent, AT&T Inc., a publicly-traded multinational telecommunications holding company headquartered in Dallas, Texas. The modern AT&T Inc. was founded as Southwestern Bell Corporation in 1983, a result of the Bell System divestiture, and later acquired its former parent, AT&T Corporation, in 2005, adopting its name. AT&T Inc. trades on the New York Stock Exchange under the ticker symbol "T". For the fiscal year ending in December 2025, AT&T Inc. reported revenues of approximately $125.6 billion and had about 133,000 employees.
As a major operating company, AT&T provides a wide range of telecommunications services. Its largest business segment is wireless services, making it one of the largest mobile phone providers in the United States. The company is also a leading provider of fiber and broadband internet services to both residential and business customers. Additional offerings include fixed-line telephone services, virtual private networking, and other voice and data solutions for enterprise clients. AT&T markets its services under brand names such as AT&T, AT&T Fiber, and Cricket Wireless.
Based on the provided data, AT&T Corp. is a defendant in patent litigation, a typical posture for a large operating company. The single tracked case, Novacloud Licensing LLC v. AT&T Inc. et al., was filed in the U.S. District Court for the District of Delaware. This aligns with the common scenario where operating companies are targeted by non-practicing entities (NPEs). The plaintiff in this case, Novacloud Licensing LLC, is a patent assertion entity formed in 2024 to license a portfolio of patents originating from telecommunications company Ericsson related to cloud computing and networking technologies.
The tracked case against AT&T Corp. was filed by Novacloud Licensing LLC, which asserts patents originally developed by Ericsson. The portfolio covers technologies described as fundamental to cloud computing, including load balancing, virtualization, and resource management. Novacloud has also filed similar infringement lawsuits against other major technology companies, such as Google, in other jurisdictions. The case against AT&T is representative of the broader trend of NPEs acquiring patent portfolios from operating companies to assert against technology implementers.
This is an ongoing case filed by Novacloud Licensing LLC against multiple AT&T entities. Recent docket activity includes a scheduling order setting deadlines for discovery and motions.
