Company patents
JATCO Ltd
JATCO LTD's patent strategy is heavily concentrated in Gearing & Transmissions, which accounts for 80.6% of its portfolio, yet saw a significant decline of 50.0% so far in 2026 after a strong 93.1% growth in 2024. Surprisingly, despite its core focus, the company is showing an emerging interest in Electric Motors & Generators, which experienced a remarkable 800.0% growth in 2024 and a further 33.3% growth in 2025, indicating a strategic shift towards electrification, though patenting in this area has also slowed so far in 2026.
