A national patent application is a patent application filed directly with the patent-granting authority of a determined state. Examples are an American patent application (which can result in a patent right in the US), a Japanese patent application or a German patent application. A national patent application must be filed in accordance with local legislation. Although in most countries the patent applicant can file the patent application him/herself, a regulation which applies in almost all countries is that a locally qualified patent attorney is required for further procedural actions. The national patent application will follow a grant procedure in accordance with the legislation in force in these countries and, in the case of a favourable assessment, result in a national patent.
