Company patents
Kureha Corporation
Kureha Corporation's patent strategy reveals a surprising recent surge in Polymer Synthesis (Polycondensation), with a 100.0% year-over-year growth in 2026 so far, making it an emerging focus despite a general decline in other polymer-related categories like Polymer Synthesis (Polymerization) (down 100.0% YoY in 2026). This indicates a strategic shift within its materials portfolio, moving away from broader polymer synthesis to more specialized polycondensation techniques, while its largest category, Batteries & Fuel Cells (20.4% of portfolio), has seen a significant decline of 71.4% in 2026 after strong growth in 2024.
