Company patents
TORAY ADVANCED MATERIALS KOREA INC.
TORAY ADVANCED MATERIALS KOREA INC. demonstrates a patent strategy heavily concentrated in materials science, with "Separation Processes (Filtration, Distillation)" accounting for 41.1% of its portfolio and showing significant fluctuation, including a 100.0% increase in 2025 followed by a -37.5% decline so far in 2026. While core areas like "Layered Products" and "Polymer Working & Compounding" also saw substantial growth in 2025 (133.3% and 66.7% respectively), the widespread sharp declines across most categories so far in 2026, including a -100.0% drop in "Coating & Surface Treatment" and "Polymer Additives," suggest a potential shift in patenting focus or a significant slowdown in new filings this year.
