Company patents
Covestro Deutschland AG
Covestro Deutschland AG's patent strategy reveals a surprising emerging focus on "Acyclic / Carbocyclic Compounds," which saw a remarkable 144.4% year-over-year growth in 2024, despite its relatively small 12.9% share of the total portfolio. While "Polymer Synthesis (Polycondensation)" remains the dominant category at 49.5% of the portfolio, its significant 56.6% decline so far in 2026 suggests a potential shift in priority, alongside other core materials categories also showing declines in the current partial year.
