Key Takeaway(s): Patent portfolios originally developed for aerospace applications may have relevance to adjacent transportation sectors. Companies developing automotive, rail, maritime, or autonomous vehicle systems should consider relevant aerospace patent activity before commercializing products.
On September 18, 2026, Honeywell Aerospace filed two patent infringement complaints against electric vehicle makers, Lucid and Rivian. Honeywell alleges that driver-assistance and autonomous-driving features in the defendants’ vehicles infringe seven patents, several of which relate to aerospace technologies.
The Lucid complaint was filed in United States District Court for the Eastern District of Texas. The Rivian complaint was filed in the United States District Court for the District of Arizona.
Honeywell asserts the same seven patents in both cases:
- U.S. Patent No. 7,088,264, “Flight Safety System Monitoring Combinations of State Values”
- U.S. Patent No. 7,286,062, “Perspective View Conformal Traffic Targets Display”
- U.S. Patent No. 7,840,352, “Method and System for Autonomous Vehicle Navigation”
- U.S. Patent No. 8,314,816, “System and Method for Displaying Information on a Display Element”
- U.S. Patent No. 8,364,334, “System and Method for Navigating an Autonomous Vehicle Using Laser Detection and Ranging”
- U.S. Patent No. 9,355,567, “System and Method for Highlighting an Area Encompassing an Aircraft That Is Free of Hazards”
- U.S. Patent No. 10,133,856, “Method and System for Managing Software License for Vehicle”
As described in the complaints, the patents concern technologies for identifying unsafe combinations of vehicle states, displaying traffic targets based on distance, integrating GPS, inertial, and image measurements, generating predicted images during low-visibility conditions, classifying laser-scan data, displaying object-free areas around vehicles, and managing access to vehicle software based on the vehicle’s operating state.
Although several patent titles and embodiments refer to aircraft, the complaints emphasize disclosures extending the technologies to other vehicles. For example, the ’264 patent discusses land-based vehicles, the ’816 patent discusses ground-based vehicles and maritime vessels, and the ’856 patent identifies cars, trucks, and motorcycles as possible applications.
Within the complaint against Lucid, Honeywell alleges that Lucid’s Air sedan and Gravity SUV infringe the asserted patents when operating versions of Lucid’s advanced driver assistance system (ADAS) named the DreamDrive platform. The complaint highlights features of the DreamDrive platform such as adaptive cruise control, automatic emergency braking, lane-departure protection, surround-view monitoring, blind-spot displays, hands-free driving assistance, and lane-change assistance.
Within the complaint against Rivian, Honeywell alleges that Rivian’s Gen 1 and Gen 2 vehicles infringe the asserted patents through Rivian’s driving assist and active safety assist features, including Driver+, the Rivian Autonomy Platform, and Autonomy+ features. The complaint discusses Rivian’s assisted-driving and safety features including highway assist, adaptive cruise control, lane change assist, lane keep assist, forward collision warning, automatic emergency braking, and universal hands free.
In both cases, Honeywell requests judgments of infringement and willful infringement, preliminary and permanent injunctive relief, compensatory damages, costs with interest and attorneys’ fees, an accounting, and a declaration that each case is exceptional. Honeywell also demands a jury trial in each action.
While still in the early stages, these cases highlight how aerospace-developed technologies and intellectual property may have relevance beyond traditional aerospace markets. Honeywell alleges that inventions first developed for aircraft safety, navigation, situational awareness, and software management are being used in modern automotive driver-assistance systems. If the allegations succeed, these cases will demonstrate the potential for aerospace-related patent portfolios to be enforced in adjacent transportation sectors that face similar technical problems.
Conversely, companies developing advanced transportation technologies, including automotive, rail, maritime, and autonomous systems, may benefit from monitoring aerospace patent activity and evaluating whether aerospace-originated intellectual property could pose barriers to commercialization for their products. While the merits of Honeywell’s allegations remain to be determined, the complaints underscore the increasingly cross-industry nature of innovation relating to autonomous vehicle perception and navigation.
