Crocs lost the legal right to protect its iconic plastic clog design after the EU court upheld a ruling that the design could not be protected under intellectual property laws. This was because Crocs made the fatal error of debuting the clog design publicly on its website in 2002 before filing for design protection in 2005, more than a year after the initial public disclosure. As a result, Crocs can no longer stop third parties from copying its extremely popular and recognizable clog design despite having sold over 300 million units globally. The case serves as a warning to designers that intellectual property should be protected as early as possible, even if a product's success is uncertain, to avoid losing protection should the design become widely copied later on.
