Adidas filed a Federal Court lawsuit against Australian online retailer White Fox, accusing the fast-fashion label of infringing its trademark three-stripe design by selling clothes featuring a four-stripe pattern. Adidas contends that White Fox is attempting to trade on the global sportswear brand's reputation through a design that Adidas characterizes as deceptively similar to its distinctive trademark. The case centres on whether White Fox's four-stripe branding violates Adidas's protected three-stripe trademark. The Guardian reported the filing but provided no statement from White Fox, details on the specific products in question, timeline for court proceedings, or prior warnings issued by Adidas before litigation.
