Trademarks are generally distinctive symbols, pictures, or words that sellers affix to distinguish and identify the origin of their products. Trademark status may also be granted to distinctive and unique packaging, color combinations, building designs, product styles, and overall presentations. It is also possible to receive trademark status for identification that is not on its face distinct or unique but which has developed a secondary meaning over time that identifies it with the product or seller. The owner of a trademark has exclusive right to use it on the product it was intended to identify and often on related products. Service-marks receive the same legal protection as trademarks but are meant to distinguish services rather than products.
A patent is a right granted by the gov't that exclues others from making, using, or selling the invention claimed in a patent
Copyright, a form of intellectual property law, protects original works of authorship including literary, dramatic, musical, and artistic works, such as poetry, novels, movies, songs, computer software, and architecture.
