Patents, trademarks and copyrights are three types of intellectual property protections.
A patent is a grant made by a government to an inventor assuring him or her the sole right to make, use, and sell his invention for a certain period of time.
A trademark is a word, name, symbol, phrase or slogan, or a combination of these items used to mark and distinguish goods or services to indicate their source or origin.
A copyright protects the writings of an author against copying. Literary, dramatic, musical, and artistic works are included within the protection of the copyright law. A copyright protects the form of expression rather than the subject matter of the work.
