Does the Office check whether an invention is patentable?

No. Article 11 of Act No. 606 of 20 June 1955 on patents states that patents are issued “with no prior examination, at the applicant’s own risks and perils, and with no guarantee either as to  the reality, novelty, or merit of the invention, or to the accuracy or faithfulness of the description.” The Industrial Property Division checks only to ensure that the application itself is in order.
