Company patents

Hanon Systems

Hanon Systems, while maintaining a strong focus on its core "Vehicle Heating / Cooling" with 41.5% of its portfolio, surprisingly shows a significant emerging interest in "Electric Motors & Generators," which saw a remarkable 200.0% YoY growth in 2024, indicating a strategic shift towards electric vehicle components. Despite this, the company also demonstrates a consistent, albeit smaller, emerging focus on "Refrigeration," which has grown by 30.0% YoY in 2024 and 23.1% YoY in 2025, suggesting diversification beyond its primary automotive heating and cooling domain.
