Trademark
What does "Trademark" mean in law?
A trademark is any word, name, symbol, device, or combination thereof used in commerce to identify and distinguish the goods or services of one producer from those of others and to indicate the source of the goods. Trademark rights arise from actual use in commerce rather than mere registration, though federal registration under the Lanham Act provides significant advantages including nationwide constructive notice and the ability to achieve incontestable status after five years. The strength of a trademark is analyzed along the Abercrombie spectrum, established in Abercrombie & Fitch Co. v. Hunting World (1976), which classifies marks as generic, descriptive, suggestive, arbitrary, or fanciful, with only the latter three being inherently distinctive.

Example
The Nike 'swoosh' symbol functions as a trademark because consumers immediately associate it with Nike's athletic products, distinguishing them from competitors' goods.
