Patent applications are initially maintained in secret by the Patent Office, however, utility patent applications are published eighteen months after their filing date, unless the owner elects never to file the application outside of the United States. Also, design patents are published at the time of issuance. These types of patents provide different forms of patent protection and more than one of each may be filed on a particular invention. Essentially, a utility patent protects an article’s functional, while a design patents protects an article’s ornamental design or appearance. Accordingly, utility patent applications include a specification that describes how to make and use the invention and claims that define the legal bounds of protection of the invention, while the drawings of a design patent applications define the protection.
