A patent is a government's grant of a property right to exclude others from the making, using, or selling of an invention. Utility patents are for new and useful processes, machines, articles of manufacture, compositions of matter, or any new and useful improvement of these. Design patents are for new, original, and ornamental designs of articles of manufacture. Plant patents are for asexually reproduced, distinct, and new varieties of plants.
A trademark is either a word, phrase, symbol or design, or combination of these, that identifies and distinguishes the source of a product of one party from those of another. A service mark is the same as a trademark except that it identifies and distinguishes the source of a service rather than a product. A mark for goods appears on the product or its packaging; a service mark appears in the advertising for the service.
Copyright is a form of protection 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 This protection is available to both published and unpublished works.
