Adidas faces a legal challenge that threatens its exclusive rights to the Trionda football used in this year's World Cup. Designer Marius Dittmar filed a complaint with the EU Intellectual Property Office, arguing the ball's four-panel design infringes on his earlier work. The dispute centers on whether Adidas's design lacks the novelty required for protection.

Dittmar, through his company 142k, claims the Trionda shares fundamental similarities with his four-panel football designs dating back to 2008. His firm has worked with sportswear brands including Jako and Hummel. The German designer initially sought a non-assertion agreement with Adidas in March 2025, but filed the IP challenge after the company declined to commit.

Adidas counters that while both balls use four panels, the curvature of seams, panel proportions, and directional design flow create a distinct overall appearance. The company emphasized that color schemes and textures have separate protections. Adidas has supplied every World Cup match ball since 1970, giving it significant marketing exposure across 14 national teams.

The EUIPO has set an August deadline for Adidas to respond. The sportswear giant maintains the dispute will have no commercial impact and that consumers will still recognize its original product. This case tests how easily competitors can replicate revolutionary football designs in a $2.1 billion industry where IP protection is essential for preventing copycat products.
