Trademarks and service marks protect distinguishing features (such as names or package designs) that are associated with particular products or services and that indicate commercial source. Intangible rights protecting the products of human intelligence and creation, such as copyrightable works, patented inventions, Trademarks, and trade secrets. Although largely governed by federal law, state law also governs some aspects of intellectual property.
