Hunter Fan Company

Hunter Fan Company's patent strategy reveals a surprising and significant focus on "Pumps (Centrifugal)", which constitutes 29.5% of its portfolio, despite a notable decline of 30.6% in 2024 and 83.3% so far in 2026, indicating a shifting priority away from this manufacturing sector. Concurrently, while smaller categories like "Lighting Devices (Functional Features)" saw a 100.0% growth in 2025, the overall trend across all listed categories shows a sharp decline in patenting activity so far in 2026, with zero patents filed in most categories.
