Adidas has lost a case trying to stop a designer from using a four-stripe design.
The sportswear giant argued that luxury brand Thom Browne Inc's four stripes were too similar to its own three stripes.
Brone argued that buyers were unlikely to confuse the two brands as - among other reasons - it had a different number of stripes.
Adidas had planned to seek more than $7.8m (£6.4m) in damages - but a New York jury sided with Browne.
Browne's designs often feature four horizontal, parallel lines encircling the garment.
Browne's legal team argued that the two brands served different customers.
Sportswear does not dominate the creations of Thom Browne Inc and their production is aimed at wealthy customers.
Browne's lawyers also argued that the stripes are a common design.
While Adidas began legal action in 2021, the battle between the two companies dates back more than 15 years.
In 2007, Adidas complained that Thom Browne was using a three-stripe design on jackets. Brone agreed to stop using it and added a fourth bar.
Since then, Thom Browne Inc. has expanded rapidly and is now sold in more than 300 countries worldwide, and in recent years has created more athletic apparel.
