Company patents
Covestro LLC
Covestro LLC's patent strategy reveals a surprising shift away from its core materials categories, with Polymer Synthesis (Polycondensation) and Polymer Working & Compounding, which together constitute nearly 97% of its portfolio, experiencing significant declines of -19.0% and -30.8% respectively in 2025. While most categories show a general decline in 2026 (so far), the rapid emergence of Printed Circuits & Electronic Assemblies, with a 200.0% year-over-year growth in 2026, suggests a strategic pivot towards electronics hardware applications, despite its current small share of 3.3% of the total portfolio.
