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. Some examples include brand names, slogans, and logos. The term "trademark" is often used in a general sense to refer to both trademarks and service marks.
Must all trademarks be registered? No, registration is not mandatory. You can establish “common law” rights in a mark based solely on use of the mark in commerce, without a registration. However, federal registration of a trademark with the USPTO has several advantages, including a notice to the public of the registrant's claim of ownership of the mark, a legal presumption of ownership nationwide, and the exclusive right to use the mark on or in connection with the goods or services set forth in the registration. For more information about “common law” trademark rights and the advantages of federal registration see the Basic Facts About Trademarks brochure.
Each time you use your mark, it is best to use a designation with it. If registered with the USPTO, use the ® symbol after your mark. If not yet registered, you may use TM for goods or SM for services, to indicate that you have adopted this as a “common law” trademark or service mark.
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. Patentable materials include machines, manufactured articles, industrial processes, and chemical compositions. The duration of patent protection depends on the type of patent granted:
Design Patents - 15 years from issuance for applications filed on or after May 13, 2015 (14 years from issuance if filed before May 13, 2015)
Utility patents and plant patents - 20 years from the date on which the application for the patent was filed in the United States or, in special cases, from the date an earlier related application was filed.
Under certain circumstances, patent term extensions or adjustments may be available. For information on patents, please visit Patents or contact 800-786-9199.
A copyright protects original works of authorship including literary, dramatic, musical, and artistic works, such as poetry, novels, movies, songs, computer software, and architecture. The duration of copyright protection depends on several factors. For works created by an individual, protection lasts for the life of the author, plus 70 years. For works created anonymously, pseudonymously, and for hire, protection lasts 95 years from the date of publication or 120 years from the date of creation, whichever is shorter.
