Company patents
BRIDGESTONE CORPORATION
Bridgestone Corporation's patent strategy, while heavily focused on Vehicle Tires (52.8% of its portfolio), surprisingly shows a strong and emerging interest in Polymer Working & Compounding, which saw a significant 40.0% year-over-year growth in 2025, indicating a deepening commitment to advanced material processing. Despite this, the overall trend across most categories, including its core Vehicle Tires, Polymer Additives, and Polymer Compositions, shows a notable decline in patenting activity in 2025 and so far in 2026, following a surge in 2024.
