THE Fiji Rugby Union is asking the companies and individuals to refrain from using its logo without proper authorisation.
In a statement, FRU said as the copyright owner, it had a number of exclusive rights under the Fiji Copyright Act (1999).
"These exclusive rights include the right to reproduce the FRU logo and the Flying Fijians name/image, and to publish and communicate the work to the public (including by way of sale, broadcast or putting the Logo and Flying Fijians name/image online).
"It is an infringement of the copyright law to do any of the acts comprised in the copyright in relation to the whole or a substantial part of the logo and the Flying Fijians name, without the permission or licence of the copyright owner.
"To rectify this infringement of the FRU's rights, we require that they immediately stop infringing the FRU's copyright and enter into a licence with the FRU for future use of the logo and Flying Fijians name/image."
FRU said it would undertake all appropriate steps to protect its trademark and its associated goodwill.
