Company patents
JTEKT EUROPE
JTEKT EUROPE's patent strategy is heavily concentrated in "Vehicle Steering & Bodies," which accounts for 82.1% of its portfolio, yet this core area has seen a consistent decline in patenting activity, including a -7.1% YoY drop in 2025 and a significant -92.3% drop so far in 2026. This suggests a potential shift away from its traditional automotive focus, despite minor fluctuations in smaller categories like "Gearing & Transmissions" (YoY +50.0% in 2024) and "Motor Control" (YoY +100.0% in 2025).
