Patenting Automotive and Mobility Inventions

The automotive sector is in the midst of the largest technology transition in its history — from internal combustion to electric powertrains, from human drivers to autonomous systems, from owned vehicles to mobility services. This transition has turned the automotive patent landscape from a relatively stable world of mechanical innovation into a fast-moving intersection of software, electronics, battery chemistry, sensor technology, and communications standards.

For inventors entering this space, the opportunities are significant — but so are the complexities of SEPs, cross-licensing, supplier agreements, and the dense prior art landscape.

What Is Patentable

Electric Vehicle Technology

Battery systems: Cell chemistry (electrode compositions, electrolyte formulations, solid-state architectures), battery management systems (BMS algorithms, thermal management, state-of-charge estimation), pack design (structural integration, crash safety, cooling), and manufacturing processes (electrode coating, cell stacking, formation cycling).

Powertrain: Electric motor designs, inverter topologies, power electronics, regenerative braking systems, and transmission mechanisms for EVs.

Charging: Connector designs, communication protocols between vehicle and charger, wireless/inductive charging systems, and grid integration technology.

Autonomous and Connected Vehicles

Sensor systems: LiDAR, radar, camera, and ultrasonic sensor designs and configurations. Sensor fusion algorithms that combine data from multiple sensor types.

Perception and decision algorithms: Object detection, lane keeping, path planning, and emergency response algorithms. These claims must be tied to specific hardware and measurable driving outcomes to navigate Alice/§101 (US) and technical effect requirements (EPO).

V2X communications: Vehicle-to-vehicle (V2V) and vehicle-to-infrastructure (V2I) communication systems, which increasingly involve SEPs related to 5G and C-V2X standards.

Traditional Mechanical Innovation

Chassis and suspension components, braking systems, steering mechanisms, thermal management, aerodynamic features, and interior mechanisms remain patentable and commercially relevant — particularly for aftermarket and Tier 2/3 suppliers.

Jurisdiction Comparison

Standards-Essential Patents in Automotive

The automotive sector's increasing reliance on communication standards — 5G, C-V2X, Wi-Fi — means that SEPs are becoming a major licensing cost for vehicle manufacturers. The Avanci patent pool licenses connected vehicle patents at a per-vehicle rate (currently around $15–$20 per vehicle for 4G, with 5G rates under negotiation).

For inventors whose technology becomes part of a communication standard: FRAND commitments apply. For vehicle manufacturers implementing standards: budget for SEP licensing costs and assess whether Avanci or individual licences are more cost-effective.

The Supplier Agreement Challenge

Automotive IP has a unique structural problem: the inventor often sells to a Tier 1 supplier, who sells to an OEM (the vehicle manufacturer). The IP ownership and licensing rights at each level must be carefully managed.

Key provisions to negotiate: Whether the patent licence flows down from the inventor to the Tier 1 to the OEM. Whether the Tier 1 obtains the right to sublicense. Whether the OEM requires indemnification from the Tier 1, who in turn requires it from the inventor. Who bears the cost of patent defence if a third party asserts a patent against the component.

File your patents before entering supplier agreements. A patent gives you leverage in these negotiations; without one, the Tier 1 or OEM has no incentive to structure IP terms favourably.
