Company patents

Emerson Electric Co.

Emerson Electric Co. surprisingly shows a significant focus on consumer-oriented "Domestic Cleaning Devices," which constitutes 28.0% of its patent portfolio, despite a sharp decline in filings by 72.7% in 2025 and 66.7% so far in 2026. Concurrently, the company appears to be shifting away from core industrial areas like "HVAC & Air Conditioning" and "Industrial Control Systems," both experiencing 100% year-over-year declines in 2025, suggesting a broader re-evaluation of its traditional patenting priorities.
