Easily double-check trademarks
This trademark list is a handy tool all copy editors should have bookmarked. Find out in seconds whether Baskin-Robbins has a hyphen (it does) and how many Z's are in Cheez Whiz (two).
But ... you don't need to follow its capitalizations, necessarily. For example, no need to cap every letter in Botox and Pez or lowercase every letter in O.B.
One thing I learned: Tater Tots is trademarked. You ought to be ashamed, Ore-Ida. (But thanks for not harrassing newspapers every time they use it lowercase.) (And what's a generic term for them, then? Tater toddlers?)
