Company patents
SUBARU CORPORATION
SUBARU CORPORATION's patent strategy reveals a surprising, albeit potentially shifting, focus on core automotive technologies, with Vehicle Control Systems dominating 23.6% of its portfolio. While categories like Electric Vehicle Propulsion saw significant growth in 2024 (YoY +67.3%) and Batteries & Fuel Cells surged by 116.7% in the same year, the sharp declines across most categories so far in 2026, such as Vehicle Lighting & Signaling at -71.9% and Vehicle Body Fittings at -66.7%, suggest a potential re-evaluation or slowdown in patenting activity across several key areas.
