Company patents
VIESSMANN CLIMATE SOLUTIONS SE
VIESSMANN CLIMATE SOLUTIONS SE's patent strategy reveals a strong, yet fluctuating, focus on core building technologies, with Refrigeration patents making up 24.6% of its portfolio and showing a significant rebound with a +100.0% YoY growth so far in 2026 after a sharp decline in 2025. While HVAC & Air Conditioning remains a key area (20.0% of portfolio), the company appears to be shifting away from Pipes & Tubing, which saw a -100.0% YoY decline in 2026, and Antennas, which also declined by -100.0% YoY in 2025 and 2026, indicating a potential streamlining of its technology focus.
