Company patents
Wacker Chemie AG
WACKER CHEMIE AG's patent strategy shows a surprising shift away from its largest category, Polymer Synthesis (Polycondensation), which makes up 32.1% of its portfolio but has seen a significant decline of -45.0% so far in 2026. While many categories experienced a dip in 2025 and 2026, the company had an emerging focus in Polymer Synthesis (Polymerization) with a remarkable +450.0% YoY growth in 2024, though this has since declined.
