Company patents
HUTCHINSON
HUTCHINSON's patent strategy reveals a surprising shift away from several key areas, with significant declines in patenting activity across most categories in 2026 so far. While 'Pipes & Tubing' remains their largest category at 21.6% of their portfolio, and 'Batteries & Fuel Cells' saw strong growth in 2025 (YoY +75.0%), both categories, along with 'Polymer Additives', 'Electric Vehicle Propulsion', and 'Vehicle Powertrain Arrangement', have seen a complete cessation of patenting activity in 2026, indicating a potential re-evaluation of R&D focus.
