A patent protects "technical inventions that are new, unique and usable in some type of industry."


A trademark protects "a word, phrase, design, or a combination thereof that identifies your goods or services, distinguishes them from the goods or services of others, and indicates the source."


A copyright protects "artistic, literary, or intellectual works that are original and exist in a tangible medium, such as paper, canvas, film, or digital format."
