Real estate tycoon Donald Trump has lost his lawsuit against an Israeli developer he accused of unlawfully using his name to boost sales of a luxury property development.

Trump demanded a share of profits in his suit, filed in May against condo builder Crescent Heights Diamond, which licensed the name Trump Plaza for a 70-story tower it planned to erect in the Israeli capital of Tel Aviv.

The mogul allegedly signed a deal giving a 25 per cent share on each unit sold in return for the use of his brand name.

Trump insisted he deserved a slice of the $36 million profit after the company sold the $44 million land to another development firm for $80 million.

Manhattan Supreme Court Judge Herman Cahn ruled that the contract between Trump and Crescent did not support Trump's claims, pointing to their contract: "Crescent 'intends to build' and never indicated that it promised to build."

Cahn added: "It makes sense there was no promise to build since Crescent did not yet own the parcels of land or have the approvals required."

Trump tells the New York Post: "We're going to appeal."
