Company patents
JOHNS MANVILLE
JOHNS MANVILLE's patent strategy reveals a surprising and consistent decline across its core materials categories, with Layered Products (Laminates, Films) showing a significant 60.0% year-over-year decrease in 2026 so far, and Polymer Working & Compounding declining by 50.0% in the same period. While most categories are experiencing a downturn, the rapid growth in Polymer Synthesis (Polycondensation) with a 100.0% YoY increase in 2025 suggests a shifting priority towards fundamental polymer innovation, despite a sharp decline so far in 2026.
