Arlington Technologies, LLC is a patent assertion entity and a subsidiary of the Texas-based patent monetization firm Dominion Harbor Enterprises, LLC. As a privately held non-practicing entity (NPE), it does not have publicly available information on its founding year, employee count, or revenue. Its business operations are centered on acquiring and litigating patents.
The company does not manufacture products or offer services. Instead, it holds and asserts a patent portfolio described as covering digital communications, enterprise telephony, and unified communications. Patents asserted in its litigation campaigns have been related to technologies such as wireless networking protocols (including 802.11ax Wi-Fi), AI-powered audio and video processing, and methods for determining device proximity.
Consistent with its status as an NPE, Arlington Technologies is exclusively a plaintiff in patent litigation. The company has filed multiple lawsuits against major technology and telecommunications companies. As indicated by the case data provided, its litigation is often filed in plaintiff-friendly jurisdictions like the U.S. District Court for the Eastern District of Texas.
The company's tracked cases include lawsuits against T-Mobile and Comcast. In the T-Mobile suit, Arlington asserted five patents related to wireless networking technology allegedly used in gateways, routers, and other devices; the case was later dismissed with prejudice, indicating a settlement. The case against Comcast involved similar wireless patents. One patent asserted against both companies, U.S. Patent 7,193,986, had multiple claims cancelled by the U.S. Patent and Trademark Office following a reexamination proceeding. Other publicly noted defendants sued by Arlington Technologies include NVIDIA, Zoom, and RingCentral.
