Honeywell Aerospace Sues Rivian and Lucid for Patent Infringement
Honeywell Aerospace filed lawsuits against electric vehicle manufacturers Rivian and Lucid for patent infringement in separate cases in two federal courts, less than three months after its spin-off from Honeywell International.
The lawsuit against Rivian was filed in the U.S. District Court for the District of Arizona, while the lawsuit against Lucid was filed on the same day in the U.S. District Court for the Eastern District of Texas, according to court records.
The Honeywell International subsidiary filed the lawsuits less than three months after its spin-off from the parent company. Honeywell Aerospace US LLC is the plaintiff in both cases.
Neither lawsuit has been made public outside the federal courts’ paid PACER system, and the patent numbers have not been released.
In the Rivian case, Honeywell alleges that Rivian’s electric vehicles infringe on seven patents it developed for aircraft but that also apply to land vehicles, according to Bloomberg Law, which first reported the lawsuit.
According to the website, the patents cover vehicle safety monitoring systems, traffic visualization systems, autonomous navigation, sensor fusion displays, laser navigation, hazard detection, and software licensing management.
Honeywell is seeking damages, an injunction, enhanced damages for alleged willful infringement, and reimbursement of attorneys’ fees, the report reveals.
It should be noted that the request for enhanced damages does not constitute a court ruling. A court can only award them if it determines that the infringement was willful and egregious.
The defendants are Rivian Automotive LLC and Rivian Automotive, Inc., and the case has been assigned to Judge Michael T. Morrissey; Honeywell has requested a jury trial.
The plaintiff submitted 14 pieces of evidence, but Bloomberg did not identify which Rivian models or systems are involved.
The case against Lucid Group, Inc. and Lucid Group USA, Inc. was assigned to District Judge Rodney Gilstrap in the Eastern District of Texas, one of the busiest patent judges in the United States, according to the report.
This complaint includes 21 exhibits—seven more than Rivian’s—which could involve additional patents, claim tables, accused products, or other material not detailed in the court record.
According to experts consulted by Bloomberg, the fact that both complaints were filed on the same day does not imply that they are based on the same patents or that they allege similar features. The seven reported categories come solely from the Rivian lawsuit.
Honeywell also requested a jury trial in the Texas case. Its local attorney in that state is Melissa Richards Smith, according to the court records.
No details have been released regarding the patents or the accused products in the Lucid lawsuit.
The plaintiff, Honeywell Aerospace, became an independent public company on June 29 and is listed on Nasdaq under the symbol HONA.
As of September 30, 2025, it held more than 9,000 active patents registered in approximately 30 countries, according to a draft registration statement filed with the U.S. Securities and Exchange Commission (SEC).
Honeywell had previously asserted patents on aviation technology, including ground proximity warning systems, in a case against Universal Avionics and Sandel Avionics in the early 2000s. There is no indication that the patents asserted against Rivian and Lucid belong to the same patent families.
