A typical cancellation, invalidation or infringement action regarding trademarks or patents in Mexico involve three different stages: the cancellation, invalidation or infringement action with the Instituto Mexicano de la Propiedad Industrial or Mexican Patent and Trademark Office (MPTO), a juicio contencioso administrativo or appeal with the Federal Court of Tax and Administrative Affairs (FCTAA) and an amparo directo or final appeal with a Federal Court of Appeals.

Under some extraordinary circumstances, it is possible to file an appeal against a decision of the MPTO with a Federal District Judge, but this not the rule and the appeal I will refer to in this article is the appeal with the FCTAA.

One of the rules of the appeals with the FCTAA has been that the appellant and the appellee may file new arguments and evidence that were not previously filed with the MPTO; we call this rule litis abierta.

The filing of new arguments and/or evidence in the appeal has caused the FCTAA to revoke some decisions issued by the MPTO, fully legal and consistent to what the parties argued and proved. Nevertheless, not all courts of appeals agree on how the litis abierta rule should be applied. The Fourth Court of Appeals in Mexico City was against the filing of new evidence of use in appeals associated to cancellation actions against registered trademarks due non-use.

A new binding precedent from the Supreme Court (73/2013)[1], published in July 2013, has set some limits to the possibility of filing new evidence in appeals, although the language the court used in drafting this precedent is ambiguous. Although the precedent does not affect the right to file new arguments in the appeal with the FCTAA, the court stated that it would not be valid to declare the invalidation of a decision based on the analysis of evidence that the appellant did not file in the original procedure in spite of having the obligation and being capable to legally do so.

The precedent was issued to solve contradictory rulings between courts of appeals. Although origin of the contradictory decisions and the precedent itself were associated to tax cases, it construes a statutory provision that applies to all appeals filed with the FCTAA, thus it will impact IP cases.

In my opinion, the language the court uses in the precedent is a little ambiguous and it raises some questions. I am concerned about the obligation of filing evidence. Under Mexican law, filing evidence is a burden, but not an obligation. Actually, some lawyers believe that proving is a right. So what did the court mean about having the obligation of filing evidence?

I think that filing evidence becomes an obligation when the government agency, i.e. the MPTO, issues a specific order requesting one of the parties to exhibit certain document in the procedure. If the MPTO issue an order requesting a specific document, then there was an obligation to file it. If the party that received the order to file the document did not do it, according to this binding precedent, it can’t file it later as evidence in the appeal. Further, any document that was not subject matter of an order from the MPTO to be filed in the invalidation/cancellation/infringement proceeding, may be filed as new evidence in the appeal, because there was no obligation to file it in the previous procedure.

However, I think the courts of appeals will construe the precedent 73/2013 in a broader way. While continuing accepting the filing of new arguments, I think the courts of appeals will decide against the filing of all new evidence in the appeal. As an example, the Tenth Court of Appeals in Mexico City construed the precedent 73/2013 in such a broad way when deciding the final appeal (amparo directo) DA 552/2013.

The litis abierta rule applicable to appeals with the FCTAA will probably continue evolving, and I hope the courts of appeals and the Supreme Court itself will publish new precedents clarifying and narrowing the broad construction of this relatively new precedent.
