Did you know that meat slaughtering services and products have brands too? And trademark protection for those brands?
Trademarks can protect any legal service or product. For example, see my blog post, Even manure brands have trademarks.
A search of the USPTO TESS system for: (slaughtering )[GS] and (live)[LD] indicates that there are 134 applications and registrations for trademarks related to slaughtering, including Paradise Locker Meats, FRENCH TIMES IN PARIS, and the nice Rinse & Chill logo below.
Brands are indeed everywhere!
