WirelessWerx IP LLC, a patent-holding company specializing in location-tracking technologies, has filed a lawsuit against Audi, citing unauthorized use of patented vehicle-tracking systems. The legal action, filed Monday in the U.S. District Court for the Eastern District of Michigan, is the latest in a series of lawsuits aimed at protecting the company’s intellectual property.

The complaint alleges that Audi manufactured, sold, and imported products that infringe upon U.S. Patent No. 7,323,982, which covers innovative systems and methods for controlling entities equipped with transponders. The technology at the heart of the suit plays a critical role in advanced vehicle-tracking and connectivity systems.

According to WirelessWerx IP, Audi used the patented technology without obtaining a license and further induced patent infringement by promoting its use through platforms such as the Audi Connect service. Instruction manuals and online resources allegedly guide users in utilizing the infringing features.

The case highlights growing Audi legal issues over vehicle tracking, as WirelessWerx intensifies its enforcement efforts across the automotive and tech sectors. Over the past several months, the company has filed more than a dozen similar lawsuits targeting major automakers and tech firms including Ford, Tesla, Subaru, Nissan, Honda, Hyundai, Mitsubishi, General Motors (OnStar), AT&T (FirstNet), Here Technologies, Pointr, Roadie, Samsara, and Zipline.

While some cases remain in early litigation stages and await formal responses, WirelessWerx voluntarily dismissed its complaint against Mitsubishi without prejudice earlier this month.

Representing WirelessWerx IP in the case is attorney William P. Ramey III of Ramey LLP. Neither Audi nor WirelessWerx representatives responded to media inquiries as of Tuesday.
