608.04(a) Matter Not Present in Specification, Claims, or Drawings on the Application Filing Date [R-07.2015]
Matter not present on the filing date of the application in the specification, claims, or drawings that is added after the application filing is usually new matter. See MPEP §§ 2163.06 and 2163.07 for guidance in determining whether an amendment adds new matter. See MPEP § 2163.07(a) to determine whether added characteristics such as chemical or physical properties, a new structural formula or a new use are inherent characteristics that do not introduce new matter. For rejection of claim involving new matter, see MPEP § 706.03(o).
