Sportswear giant Adidas has won the first set of a High Court battle with the tennis establishment over the stripes on players' shirtsleeves.
Andre Agassi wears the controversial style of shirt
The International Tennis Federation (ITF) has on-court kit rules to prevent players becoming walking adverts.
It said that Adidas' "three stripes" were "manufacturer identification" which breached the code.
But Adidas will be allowed to keep using the design worn by stars such as Tim Henman and Martina Hingis.
Design or logo?
On-court dress logos should be restricted to 26 sq cm, according to ITF rules.
However, the German sports firm said the stripes were a "design effect" rather than a logo.
Calling for the injunction, Adidas said it did not have time to change its designs ahead of the Wimbledon championship, which starts later this month.
The injunction was made against the Lawn Tennis Association - the sport's governing body in the UK - which runs Wimbledon, as well as the ITF and the United States Tennis Association.
A judge in London's High Court rejected a counter-bid by the defendants to have Adidas' case struck out.
The case will be heard in full later in the year.
