Comic Enterprises claimed that Twentieth Century Fox's production of Glee had breached its trade mark rights to the phrase The Glee Club - and the firm said it had been harmed as a result. Twentieth Century Fox disagreed.
A judge today ruled that Twentieth Century Fox had "infringed" a trade mark. But he said Comic Enterprises had not been damaged.
Deputy High Court Judge Roger Wyand QC made no mention of any compensation in a written ruling published following a High Court hearing in London. He said any subsequent issues would be analysed at another hearing.
