Michelin is one of the leading patent filers in anti-corrosive tire reinforcements. The company employs advanced surface coating techniques, such as proprietary coatings or treatments, to protect tire reinforcements from corrosion. These coatings could include zinc, phosphate, or specialized polymer-based coatings tailored for anti-corrosive properties. Michelin has developed tire reinforcements using polymer-based or composite materials as alternatives to traditional steel reinforcements. These materials, such as fiberglass, carbon fiber, or reinforced plastics, offer corrosion resistance while potentially reducing tire weight and improving fuel efficiency. Some other key patent filers in this space include Bridgestone and Bekaert.

In terms of application diversity, Ecosil Technologies leads the pack, while Goodyear Tire & Rubber and Xingda International stood in the second and third positions, respectively. By means of geographic reach, Tokyo Rope Manufacturing held the top position, followed by Bekaert and Michelin
