Company profile

T-Mobile USA, Inc., commonly known as T-Mobile, is a major American wireless network operator headquartered in Bellevue, Washington. It is a publicly traded subsidiary of the German telecommunications company Deutsche Telekom AG, which is the majority shareholder. T-Mobile is one of the largest wireless carriers in the United States, reporting approximately 75,000 employees and revenue of $78.6 billion in 2023. Its stock trades under the ticker TMUS on the NASDAQ exchange.

T-Mobile provides wireless telecommunication services, including voice, messaging, and data for postpaid, prepaid, and wholesale customers. The company operates its flagship brands, T-Mobile and Metro by T-Mobile, offering services through its retail stores, website, and other distribution channels. In addition to services, T-Mobile sells a range of wireless devices such as smartphones, tablets, and accessories from various manufacturers. The company has built out an extensive 4G LTE and 5G network across the United States.

Based on the provided data, T-Mobile is exclusively a defendant in patent litigation, indicating its position as an operating company defending against infringement claims. The company has been sued four times, with zero cases filed as a plaintiff. Three of the four tracked cases were filed in the U.S. District Court for the Eastern District of Texas, a venue widely considered favorable to patent plaintiffs.

The plaintiffs in the tracked cases appear to be non-practicing entities (NPEs). For instance, Arlington Technologies, LLC is identified as an NPE and an entity of the Dominion Harbor Group. Similarly, Intent IQ, LLC has engaged in extensive litigation, targeting numerous large technology companies and reportedly earning significant revenue from patent litigation. The other plaintiffs, Advanced Broadband LLC and Disintermedation Services Inc., also appear to be patent assertion entities based on their litigation history. The cases against T-Mobile involve technologies related to broadband communications and wireless networking.
