Mexico. Formulation patents banned from the Linkage Gazette disregarding a Supreme Court's decision.

 
   On Friday, August 13, 2010, the Mexican Trademark and Patent Office (IMPI) made available through its website the new edition of the linkage gazette. Regrettably, IMPI decided to exclude formulation patents, limiting the inclusion criteria to compound patents.  There are formulations patents included in the list but derived from Court´s orders.

   The non inclusion of formulation patents disregards the petition by the Pharmaceutical Association of R&D companies (AMIIF) and does not follow the jurisprudence of the Mexican Supreme Court ruling that formulation patents are to be included in the Linkage Gazette.
 
   Legally speaking, as an administrative authority, IMPI is not bound to follow judicial precedents; nevertheless, there is broad dissatisfaction with the political decision taken by IMPI regarding the denial to include formulation patents in the Linkage Gazette, since following the Supreme Court's Criterion would have avoided further litigation from patent holders.

   The non inclusion of valuable formulation patents is contestable within the next fifteen working days. 
Any litigation proceeding at this point will be benefitted by the Supreme Court's precedent which is mandatory for District and Circuit Courts and provides guidelines to decide these cases.

   Of course, inclusion of formulation patents in the linkage gazette provides grounds to prevent or challenge marketing authorizations granted to third parties in violation of formulation patents which in many cases have expiration dates beyond the initial compound patent.  

   Additionally, inclusion of formulation patents is pivotal, as the formulation of drugs is reviewed by the Regulatory Authority (COFEPRIS) upon studying applications for marketing authorizations.  Since safety and efficacy of a drug reviewed by COFEPRIS is not limited to compounds, there is no rationale to limit the linkage regulation to compound patents by the linked authorities (IMPI and COFEPRIS), specially, when the highest Court in México has decided that the formulation patents for allopathic medicines including an identified compound should be included in the gazette.
