Bridgestone Americas Tire Operations, LLC
Bridgestone Americas Tire Operations, LLC, while heavily focused on "Vehicle Tires" (65.1% of its portfolio), shows a surprising and rapid emerging focus on "Polymer Compositions" and "Polymer Additives," which saw year-over-year growth of +222.2% and +90.9% respectively in 2025, indicating a strategic shift towards advanced materials science beyond just tire manufacturing. However, patenting activity across most categories, including its core "Vehicle Tires," shows a significant decline so far in 2026, with "Polymer Synthesis (Polymerization)" and "Plastics Shaping & Molding" having no patents filed this year.
