Company patents
Grundfos Holding A/S
GRUNDFOS HOLDING A/S's patent strategy reveals a surprising shift in focus, with a significant decline in its core 'Pumps (Centrifugal)' category, which represents 47.1% of its portfolio, experiencing a -54.5% YoY drop in 2026 so far, following a -50.0% decline in 2025. While 'Industrial Control Systems' saw a remarkable 150.0% YoY growth in 2024, it has since declined sharply, indicating a potential re-evaluation of its investment in this area, with zero patents so far in 2026.
