Adidas is currently embroiled in a legal battle to maintain its design protection for the Trionda, the official match ball for the 2026 World Cup, within Europe. The dispute, which is being reviewed by the European Union Intellectual Property Office (EUIPO), centers on the ball's distinctive four-panel construction. While Adidas publicly minimizes the potential impact, stating it would not have a "commercial impact" and only affect exclusive use of the panel design in Europe, losing this protection could allow competitors to legally produce similar four-panel footballs in key markets.
The challenge was initiated by Marius Dittmar, a 34-year-old designer who owns the firm 142k. Dittmar claims to have designed similar four-panel footballs previously and argues that the Trionda's design is not significantly different from a 2008 U.S. patent. He filed a request for cancellation with the EUIPO in October 2025, citing this older U.S. patent that describes a similar four-panel ball design. Adidas had secretly filed its Trionda design with the EUIPO in 2023 but only officially activated the protection in late March 2025, after learning of Dittmar's nearly identical registration with the German Patent and Trademark Office in November 2023.
The Trionda's revolutionary construction, featuring four large, star-shaped panels instead of traditional multi-panel designs, is a core element of Adidas's football product portfolio, extending beyond the World Cup ball to products like the "Conext 26 Pro" and likely upcoming balls for the Champions League, MLS, and Bundesliga. Adidas maintains that it holds three separate protections for the Trionda covering the panel shape, color design, and surface structure, and that a cancellation would only impact the exclusive use of the panel design, not the use of the panel shapes themselves. The EUIPO is currently assessing whether the Trionda's design significantly differs from the "existing wealth of forms" established by the 2008 U.S. patent.
