and it wouldn't matter iof they called them a RALEX either. It is every bit as illegal to counterfeit badly as it is to do a wonderful job.
Ditto what Bill said. I'll add in summary that the issue on trademark infringement always involves the factual analysis of whether the allegedly infringing mark 'creates a likelihood of confusion, mistake and/or deception with the consuming public. The confusion created can be that the defendant's products are the same as that of the plaintiff, or that the defendant is somehow associated, affiliated, connected, approved, authorized or sponsored by plaintiff.' See HERE.
Ralex, Bolex, Pollx, Polex, etc. - it all falls into that 'likelihood of confusion' gray area, i.e. it doesn't matter that the allegedly infringing mark doesn't use the idential word in the mark.
