An action that questions the constitutionality of the legal provisions dealing with pipeline patents should be tried in September. Also called import or revalidation patents, they were granted to patented products abroad, but these patents were already in the public domain.
The justification of the Brazilian General Attorney of the Republic (PGR) is that these legal provisions allowed patents granted abroad to be automatically applied in Brazil without substantial verification of the qualities and innovations of the product, with a maximum duration of 20 years. More than 1,100 patent applications were granted automatically in 1997. But, today, they have fallen into the public domain.
One of the arguments about unconstitutionality is precisely in its legal nature, since it seeks to make patentable, to the detriment of the principle of novelty, that which is already in the public domain, promoting the legislator, thus, a kind of expropriation of a common good of the people without any constitutional protection.
According to such experts, pipeline patents favored foreign multinationals that privatized – without paying anything to the treasury – technology that was already in the public domain.
Tha judgement would be important to show that the Brazilian Supreme Court understands that it is not possible to enact a law and give patents to technologies that were already old, and already known, in this way, it would be possible to recognize the nullity of patents and the consequent return of money that was sent abroad.
Others claim that these patents are constitutional since all necessary requirements for them to be valid were fulfilled. The revalidation regime abroad is not an exclusivity of Brazil. Any decision to the contrary would generate much legal uncertainty, according to other experts.
