The words 'we sing for Wanderers', famously sung by the controversial RBB active supporter group, was originally issued with a trademark application by FFA on September 1, 2016.

The trademark application - which would see FFA gain some legal rights over the publicity and public use of the chant - is still displayed on the IP Australia government website as "under examination". 

The trademark application seeks to allow FFA unlimited use of the phrase for advertising, merchandise, sports programs and other functions and entertainment purposes.

The RBB, which have been extremely vocal in their opposition to the sport's governing body, were predictably angered by the application. Some fans pointed out the difficulty in objecting to trademark applications.

News of FFA's impending trademark comes after the organisation sent Western Sydney Wanderers a 'Show Cause' notice after RBB members lit flares at the Sydney Derby.
