On May 13, 2026, the Argentine Patent Office (INPI) published Resolution No. 142/2026, introducing important amendments to Resolution INPI No. P-056/2016, which regulates the accelerated examination mechanism based on foreign granted patents.

Until now, the application of Resolution P-056/2016 was limited to patent applications whose substantive examination had not yet begun.

The newly enacted Resolution 142/2026 removes this restriction by repealing Article 4 of Resolution P-056/2016 and amending Article 5 accordingly.

As a result, applicants may now voluntarily request the application of Resolution P-056/2016 at any stage of prosecution, provided that no final administrative decision granting or rejecting the application has yet been issued.

The amendment maintains the requirement to submit claim correspondence documentation adapting the Argentine claims to those granted abroad, together with the corresponding translation.

The remaining conditions for the application of Resolution P-056/2016 remain unchanged, and the National Patent Administration retains discretion to assess compliance with the applicable legal and patentability requirements on a case-by-case basis.

According to the new regulation, the Patent Office shall issue its decision within sixty (60) days from the filing of the request.

This amendment is expected to significantly broaden the practical availability of accelerated examination strategies for pending patent applications in Argentina and provide greater procedural flexibility to applicants.

Resolution No. 142/2026 entered into force upon its publication in the Official Gazette on May 13, 2026.
