Executives at Twentieth Century Fox Television have been embroiled in legal action since 2011 when the owners of a British comedy chain sued over claims the show's name is too similar to their The Glee Club venues.

In 2014, a High Court judge ruled in favour of the comedy club owners, Comic Enterprises, ordering Glee producers to change the name of the show for U.K. broadcasts or pull the series from screens completely.

TV chiefs attempted to overturn the decision, but the challenge was rejected by judges at Britain's Court of Appeal on Monday (08Feb16).

However, a representative for Twentieth Century Fox Television indicated the legal wrangling is not over.

"We note the court of appeal's decision and welcome its consideration of the outstanding issues. We remain committed to proving the merits of our case and to delivering Glee to all of its fans in the U.K," a spokeswoman told editors at British newspaper The Guardian.

Glee, which originally featured Cory Monteith and Lea Michele as members of an American High School choir, finished its original run of six series last year (15).
