A Technical Evaluation Report is prescribed under the Patent Act, which allows anyone to request TIPO for a Technical Evaluation Report regarding a utility model, in order to clarify if said utility model complies with the patentability of utility models. However, the Technical Evaluation Report rendered to a utility model does not have a legal binding effect, and it is not an administrative order, either. It is merely a reference for exercising the rights to utility model patent or for technical reference. Anyone having a cause as to that a utility model patent should not be approved, may according to Article 107 of the Patent Act institute an invalidation action in order to revoke such utility model patent.
