According to GlobalData’s company profile on Bridgestone, Anti-skid tyre treads was a key innovation area identified from patents. Bridgestone's grant share as of January 2024 was 35%. Grant share is based on the ratio of number of grants to total number of patents.

A recently granted patent (Publication Number: US11883720B2) discloses a golf ball design that aims to optimize spin rate and launch angle on approach shots at specific head speeds. The golf ball comprises a core and a cover with specific characteristics to meet the desired performance criteria. The cover includes an outermost layer with a coating composition consisting of a urethane coating containing a base resin comprising a polyester polyol, an acrylic additive, and a solvent, along with a curing agent comprising a polyisocyanate. The patent specifies formulas to ensure the spin rate and launch angle meet the desired parameters under both wet and dry conditions.

Furthermore, the patent details the specific components used in the coating composition, such as the acrylic additive comprising a silicone-modified acrylate and the polyisocyanate, specifically hexamethylene diisocyanate. The mixing ratio of different forms of hexamethylene diisocyanate is also outlined, along with the recommended amount of acrylic additive relative to the base resin. The patent covers variations in head speed, with different sets of formulas provided for golf balls designed for head speeds of 20 m/s and 10 m/s, ensuring consistent performance across different conditions. Overall, the patent aims to enhance the performance of golf balls by optimizing spin rate and launch angle for improved playability on approach shots.
