"100% beef" is a factual claim, and not subject to Trademarks; McDonalds Trademarked "100% PURE ALL-AMERICAN BEEF" in 1982.

Even that doesn't mean that the patty is JUST beef. Thanks to legalese, the only thing a claim like that would guarantee is that the beef portion of the hamburger patty is "100% PURE ALL-AMERICAN BEEF".
It could be 99% filler and not be a lie.
