Intellectual property is the set of legal rights to an expressed name or idea.
It is property that results from the fruits of mental labor. A trademark is a word, phrase, symbol or design, or combination of words, phrases, symbols or designs used to identify the source and quality of a business product. For example, Nike identifies a particular brand of athletic shoe. A service mark is the same as a trademark except that it identifies and distinguishes the source of a service rather than a tangible product. The terms trademark or mark are used commonly to refer to both trademarks and service marks.
