Company patents
Endress+Hauser Flowtec AG
Endress + Hauser Flowtec AG's patent strategy, while heavily concentrated in Flow / Volume Measurement (80.0% of its portfolio), shows a surprising, albeit recent, shift in focus. Despite a significant decline in 2025 (-37.2% YoY) and so far in 2026 (-26.5% YoY) for its core Flow / Volume Measurement, the company saw a remarkable surge in Material & Chemical Analysis patents in 2024 (+188.9% YoY), indicating an emerging priority in this area, even though it also experienced a decline in 2025 and so far in 2026.
