According to the public information inquiry, a patent application is a request made by the inventor, designer or other subject with the right to apply to the patent office to obtain patent rights for an invention or design. According to the Chinese Patent Law, a patent application must submit an application, description, claims, abstract, drawings, and priority request to the Patent Office. The two documents of drawings and priority request are not essential for every application, but they are beneficial to patent applications.
