Agnès Poulbot – Insights on Inventions, Patents, and Patent Applications

Dr. Agnes Poulbot is a Ph.D. in applied mathematics, and currently holds the position of senior expert in 3D design simulation programs at Michelin. She is a mother of five and loves solving puzzles. One such puzzle she untangled is related to truck tire treads which earned her European inventor of the year award in 2018 given by the European Patent Office (EPO).

Dr. Agnes Poulbot invented a regenerative tire tread technology in which a new tire tread emerges when the current one in contact with the ground wears off. The technology is marketed as Reginion by Michelin and extends the lifespan of a tire by 20% and reduces 3724 kg C02 emission per tire.

She didn’t follow the traditional approach of using a single layer but designed a tire with multiple shallow treads, stacked on top of each other. Next, she developed a special mold using 3D printing to make mass production possible. You can read Dr. Agnes’ patent on re-generative tire tread by clicking here. Below we have brought a quick snapshot of her patent portfolio.
