A patent is a limited duration property right relating to an invention, granted by the United States Patent and Trademark Office in exchange for public disclosure of the invention.
A trademark is a word, phrase, symbol, and/or design that identifies and distinguishes the source of the goods of one party from those of others. A service mark is a word, phrase, symbol, and/or design that identifies and distinguishes the source of a service rather than goods. The term “trademark” is often used to refer to both trademarks and service marks.
A copyright protects works of authorship, such as writings, music, and works of art that have been tangibly expressed.
