Didn’t they also have filler then remove it to be 100% beef at some point?

100% beef is the topic of an ongoing lawsuit[0].

100% beef is a trademark.

		"100% beef" is a factual claim, and not subject to Trademarks; McDonalds Trademarked "100% PURE ALL-AMERICAN BEEF" in 1982. https://www.trademarkia.com/100-pure-all-american-beef-73352...

Only after attempts to call one of their suppliers or processors "100% Beef" failed.

		I recall a similar claim regarding pop music compilation CDs advertised as being performed by "The Original Cast", which was really a group by that name playing covers of popular songs. Or another being "Made in USA", where Usa was a city in Korea.
