Company patents
Jing-Jin Electric Technologies Co., Ltd.
Jing-Jin Electric Technologies Co., Ltd. demonstrates a primary focus on Gearing & Transmissions, which constitutes 52.6% of its portfolio, yet this category has seen a significant decline of 41.7% so far in 2026. Surprisingly, despite its core business in electric powertrains, the company's patenting in Electric Motors & Generators experienced a dramatic 500.0% growth in 2025 after an 87.5% drop in 2024, indicating a volatile but potentially re-emerging focus, while categories like Power Conversion (DC/AC, DC/DC) and Heat Exchange Components show a clear shifting priority with 100.0% declines so far in 2026.
