Novelty Requirements:

An industrial design is new if it has not been disclosed, in any place of the world by publication, or in Sao Tome and Principe by oral disclosure, use or any other way before the date of filing or, if applicable, from the priority date.

Disclosure to the public of an industrial design shall not be taken into consideration if the disclosure

a) occurred within twelve months preceding the filing date or where applicable, the priority date of the application; and

b) was as a result of acts directly or indirectly committed by the applicant or the applicant's predecessor‐in‐title or of an abuse
committed by a third party with regard to the applicant or the applicant's predecessor in title.


Industrial design means any assembly of lines, colours or any forms of three dimensions, associated or not to lines and colours, since that assembly or that form provide for a special aspect to an industrial or craft product and can be used as a model for manufacturing an industrial or craft product.

Design protection may not be obtained for the elements of an industrial design that are used only for obtaining a technical effect.

An industrial design which is contrary to public order or public morality is not registrable.

Filing Requirements:

  • Power of Attorney (can be late filed).
  • Drawings or photographs that adequately represent the subject matter of the industrial design (required on the day of filing).
  • An indication of the kind of products for which the industrial design is to be used.
