Pedro Marcos Nunes Barbosa writes: In April 2018, the Brazilian Superior Court of Justice (STJ) ruled on a controversial patent term extension scheme, for the third time since Brazil adopted TRIPS compliant legislation in 1996. The first ruling on this topic, upheld by the STJ, was decided, unanimously, in the year 2009 (docket REsp 960.728, Justice Andrighi). In that case, a famous agrochemical multinational company sought an exotic interpretation of the impacts brought by the minimum deadline granted to a patent, since the WTO’s annex treaty imposed the uniform extension of 20 years. In other words, although the agrochemical company had obtained its exclusivity right in a pre-TRIPS context (where Brazilian Law guaranteed a 15 years property right), but unsatisfied, after the Agreement was implemented, the plaintiff requested a judicial pass for a five year extra period of competition absence.
