Lawyers at Kilpatrick Stockton scored a $304 million victory for shoe company Adidas AG late Monday in what the law firm says could be the largest trademark verdict in U.S. history.

Adidas sued retailer Payless ShoeSource, Inc. in 2001 in federal district court in Oregon for selling imitation footwear that looked like Adidas’s three-stripe shoes. Following a 15-day trial, a nine-person jury took two days to decide that Payless had violated Adidas’s trademarks.
