Basic Types of Intellectual Property

Patents, trademarks and copyrights protect different types of intellectual property.

A patent protects an invention. A trademark typically protects brand names and logos used on goods and services. A copyright protects an original artistic or literary work. For example, if you invent a new kind of vacuum cleaner, you would apply for a patent to protect the invention itself. You would apply to register a trademark to protect the brand name of the vacuum cleaner. And you might register a copyright for the TV commercial that you use to market the product. A brief overview of each of these types of intellectual property is provided below.


A patent is an intellectual property right granted by the Government of the United States of America to an inventor “to exclude others from making, using, offering for sale, or selling the invention throughout the United States or importing the invention into the United States" for a limited time in exchange for public disclosure of the invention when the patent is granted.

There are three types of patents:

  • Utility patents may be granted to anyone who invents or discovers any new and useful process, machine, article of manufacture, or composition of matter, or any new and useful improvement thereof
  • Design patents may be granted to anyone who invents a new, original, and ornamental design for an article of manufacture
  • Plant patents may be granted to anyone who invents or discovers and asexually reproduces any distinct and new variety of plant


A trademark is generally a word, phrase, symbol, or design, or a combination thereof, that identifies and distinguishes the source of goods of one party from those of others. A service mark is the same as a trademark, except that it identifies and distinguishes the source of service rather than goods. A trademark may be located on a package, a label, a voucher or on the product itself. For the sake of corporate identity trademarks are also being displayed on company buildings. The trademark owner can be an individual, business organization, or any legal entity. You can establish rights in a mark based on use of the mark in commerce, without a registration.

Owning a federal trademark registration on the Principal Register provides a number of advantages:

  • A legal presumption of your ownership of the mark and your exclusive right to use the mark nationwide on or in connection with the goods/services listed in the registration (whereas state registration only provides rights within the borders of that one state)
  • Public notice of your claim of ownership of the mark; listing in the U.S. Patent and Trademark Office's online database
  • The ability to record the U.S. registration with the U.S. Customs and Border Protection Service to prevent importation of infringing goods
  • The right to use the federal registration symbol "R-Circle"; the ability to bring an action concerning the mark in federal court
  • The use of the U.S. registration as a basis to obtain registration in foreign countries


Copyright is a form of protection provided by the laws of the United States to the authors of “original works of authorship," including literary, dramatic, musical, artistic, and certain other intellectual works. This protection is available to both published and unpublished works.

  • Reproduce the copyrighted work
  • Prepare derivative works based on the copyrighted work
  • Distribute copies of the copyrighted work
  • Perform the copyrighted work publicly
  • Display the copyrighted work publicly

It is illegal for anyone to violate any of the rights provided by the copyright law to the owner of copyright. These rights, however, are not unlimited in scope. In some cases, these limitations are specified exemptions from copyright liability.

One major limitation is the doctrine of “fair use." In other instances, the limitation takes the form of a “compulsory license" under which certain limited uses of copyrighted works are permitted upon payment of specified royalties and compliance with statutory conditions.
