Article 19, section VII of the Mexican Industrial Property Law establishes, inter alia, that methods of therapeutic treatment applicable to the human body and to animals shall not be considered as inventions; as a result, such methods are expressly excluded from patentability. However, under Mexican law and practice, there is no exclusion of the possibility for patenting a (new or known) substance or compound for any specific use in a method of therapeutic treatment, as long as such use is new and the claims directed to this kind of matter are written under the first medical use format (compound X for use as a medicament and/or in the treatment of condition Y), or under the subsequent medical use format, also named second medical use format or Swiss-type format (the use of a compound X for manufacturing a medicament for treatment of disease Y).
