The Hell's Angels are no strangers to the legal system either. Apparently, they are quite litigious when it comes to protecting their intellectual property. They sued Disney for allegedly exploiting the Hell's Angels image in the move "Wild Hogs,' and they sued the Alexander McQueen fashion house for allegedly using the Hell's Angels 'winged skull' logo. Good for them.
The report says copyright infringement when I believe that the real cause of action is actually trademark infringement. If it really is a copyright case and not a trademark case, then I think the Hell's Angels were poorly advised. The maker would have a pretty decent fair use defense, although I don't really see a defense to trademark infringement. No matter, it still makes for an interesting story.
