Company patents
Zhejiang Liankong Technologies Co., Ltd
Zhejiang Liankong Technologies Co., Ltd's patent strategy reveals a surprising shift away from its core automotive categories, with significant declines in areas like Vehicle Heating / Cooling (-66.7% YoY in 2026 so far) and Vehicle Powertrain Arrangement (-25.0% YoY in 2026 so far), despite these still representing 20.0% and 22.2% of its portfolio respectively. Concurrently, the company shows an emerging focus on Electric Vehicle Propulsion, with 2 patents filed so far in 2026 after no activity in prior years, indicating a potential pivot towards electrification.
