In US trademark law, two separate companies can legally own identical or nearly identical trademarks, provided their products or services operate in completely different fields and consumers are not likely to be confused logo. A trademark does not grant an absolute monopoly over a word or logo, it only protects within specific commercial contexts.
Some examples of this are: - Dove chocolates and Dove soap - Apple computers and Apple records (the Beatles' record label) - Delta airlines and Delta dental - Gerber baby products and Gerber outdoor gear
