Trademark protection is available for any word, name, symbol, or device, or any combination thereof that serves to identify the source of the goods or services. This broad statutory definition provides trademark protection for business names, slogans, product designs, sounds, smells, and a variety of other symbols.
While most people are familiar with trademarks for large, recognizable business names, trademark rights may be available for atypical devices such as the color of home insulation, the smell of fuel additive, and the sound of the Xbox start-up sound/swoosh.
