Fast fashion retail company Forever 21 has lost a trademark battle in the Philippines to a local company using the same name, according to local media reports.

The country's Court of Appeals upheld a decision by its Intellectual Property Office that local company Forever 21 Fashion Apparel was entitled to use the "Forever Twenty One" mark, the reports stated.

The Filipino company was entitled to use the mark locally because it registered it in March 2003 - several months before the US retailer lodged its registration in December 2003, the court said.

The ruling overturned the US company's claims that it was entitled to use the trademark since it had long used it in many countries around the world.

Established in the US 25 years ago, Forever 21 now has about 500 stores around the world.

Neither company was available for comment.
