Company patents
Copeland LP
Copeland LP's patent strategy reveals a strong, sustained focus on Refrigeration, accounting for 36.8% of its portfolio, with a remarkable 950.0% YoY growth in 2024, followed by a steady 4.8% growth in 2025, although patenting in this area has slowed so far in 2026. Surprisingly, while core building technologies like HVAC & Air Conditioning saw significant growth (44.4% YoY in 2025), the company also exhibits a notable, albeit declining, interest in manufacturing-related Pumps (Centrifugal), which represents 13.8% of its portfolio but experienced a 30.0% decline in 2025 and a further 57.1% decline so far in 2026, indicating a potential shift in priorities away from certain manufacturing components.
