PCT Patents Applications in Peru

On June 6 2009, the Patent Cooperation Treaty (PCT) came into force in Peru. The PCT is a system that creates a single patent application procedure for all the 142 member countries . A single search is carried out that is valid for all member countries, together with a written opinion regarding the novelty, inventiveness and industrial applicability required for the granting of a patent.

Moreover, this treaty provides benefits to:

  • The patent applicants: the PCT allows applicants to delay entry into the national phase, where the highest investment is carried out, until 30 months, offering a prior written opinion on the possibilities of approval. It also avoids unnecessary costs, as it allows applicants to obtain an international preliminary examination on the patentability of the invention.
  • The member countries: since they receive the result of the international search and a written opinion or report of the preliminary examination on which can be based the granting or refusal of the patent, the workload of member patent offices is reduced.
  • The PCT is the most effective instrument for obtaining patents worldwide because of the tools provided by the system, which are available to all member applicants. This treaty therefore marks the entry of Peru into a new stage of modernization and globalization.
