The issue here was whether a company could trademark "Fish Fri"--
"There are many edible fish in the sea, and as many ways to prepare them as there are varieties to be prepared. Even piscatorial gastronomes would agree, however, that frying is a form of preparation accepted virtually around the world, at restaurants starred and unstarred. The paucity of synonyms for the words "fish" and "fry" suggests that a merchant whose batter mix is specially spiced for frying fish is likely to find "fish fry" a useful term for describing the product."
