Adidas grandson claims A.D. One

Published on .

A.D. One, San Mateo, Calif., marketer of athletic shoes, says it will fight to establish a trademark that has been challenged by footwear giant Adidas. A.D. One founder Adi Daller is the grandson of Adolph Dassler, who started a company that became Adidas in Germany in 1920. Adidas said the A.D. One logo too closely resembles the Adidas trademark, and its slogan, "From the world's first family in athletic footwear," might confuse consumers. The dispute is now pending in the U.S. Patent & Trademark Office.
