India allows discount in official fee to natural person, start up as well as small entity. When the patent application is assigned to non-natural person (small entity, start up or other than small entity), the entire discounted fee has to be paid at the time of registration of assignment. If start up or small entity status is claimed, the document in support must be filed along with the Application.  While paying any fee, every time document in support of small entity or valid document in support of start-up continuance is to be filed.
