Company patents
JSR CORPORATION
JSR CORPORATION's patent strategy reveals a surprising shift away from its dominant Photolithography category, which accounts for 60.4% of its portfolio but saw a significant 39.0% decline in patenting activity so far in 2026. While core semiconductor and materials categories like Polymer Synthesis (Polymerization) and Semiconductor Manufacturing Process are also experiencing declines in 2026, the company shows an emerging focus in the pharma_biotech sector, particularly with a 33.3% YoY growth in Heterocyclic Compounds (Pharma) in 2026, despite overall fluctuations in this sector.
