Ball's claim that the name Eden Project, which he had registered as a trade mark in 1997, was his personal property, was rejected by the High Court last week.
Mr Justice Laddie concluded that "in registering the mark in his own name and for his own benefit" Ball was in clear breach of his duty to the Eden Project company he had co-founded in 1994 with Tim Smit, its current chief executive.
Ball, who claims that he has been excised from the project's history without due compensation, has agreed to transfer the registered trademark to the company and pay £27,500 in legal and court fees within three weeks. He was given a week to transfer his rights in the trademark to the Eden Project.
Mr Justice Laddie noted that nothing said on the trademark issue should reflect on Ball's other claim.
In a brief statement, the Eden Project said it was pleased with the decision.
