Company patents
CARRIER CORPORATION
CARRIER CORPORATION's patent strategy reveals a surprising shift away from its core competencies, with significant declines across its top categories like Refrigeration (-18.9% YoY in 2025) and HVAC & Air Conditioning (-13.7% YoY in 2025). While most categories show a downward trend, the rapid 75.0% YoY growth in Power Distribution & Storage in 2025 suggests an emerging focus on energy management, despite the overall portfolio contraction.
