Honeywell Aerospace has filed two new lawsuits against Rivian and Lucid, accusing the two electric vehicle manufacturers of infringing on its patents.
According to a report from Bloomberg Law, Honeywell alleges that Rivian is using seven patented technologies without permission. These cover safety monitoring, autonomous navigation, traffic display systems, sensor fusion, laser-based navigation, hazard detection, and software licensing management.
While the technologies were initially developed for aviation, Honeywell argues that its intellectual property also extends to applications in ground vehicles.
Honeywell is seeking financial compensation, an injunction, attorneys’ fees, and enhanced damages for what it alleges was willful infringement. The company has also requested a jury trial.

Both lawsuits were filed on September 18, 2026, less than three months after Honeywell Aerospace separated from Honeywell International to become an independent publicly traded company.
Neither Rivian nor Lucid had filed a response to the allegations as of Monday.
