Company patents
Rheem Manufacturing Company
Rheem Manufacturing Company's patent strategy shows a strong, albeit fluctuating, commitment to its core building sector, with HVAC & Air Conditioning (24.0% of portfolio) and Refrigeration (19.5% of portfolio) dominating, despite a notable decline in patenting activity so far in 2026 for both categories (YoY -51.9% and -69.6% respectively). Surprisingly, while core manufacturing categories like Industrial Control Systems and Industrial & Autonomous Control saw significant drops in 2025 and zero patents so far in 2026, the company showed an emerging focus in Electric Heating & Lighting Control and Buildings (Specially Adapted), both experiencing 100.0% YoY growth in patent filings so far in 2026, albeit from a smaller base.
