Legal analysis: Modifications to design patent application documents shall not exceed the scope of the original pictures or photos. A patent application is a document that expresses technical content in a prescribed manner through text. However, due to limitations of the text itself or the writing skills of the patent application writer, the text of the patent application document may not accurately express the applicant when the application is submitted. Therefore, the patent applicant also enjoys the right to amend the patent text after submitting the application documents on the filing date.
Legal basis: "Patent Law of the People's Republic of China" Article 33 Applicants may modify their patent application documents, but modifications to invention and utility model patent application documents are not allowed. Beyond the scope recorded in the original description and claims, modifications to the design patent application documents shall not exceed the scope represented by the original pictures or photographs.
