Mexico and Argentina: IP Reforms in 2026
 (2).png "Mexico and Argentina: IP Reforms in 2026")
Argentina and Mexico have both implemented notable intellectual property reforms in 2026. Argentina has adopted a new inflation-linked fee structure for official industrial property fees, while Mexico has enacted substantial amendments to its industrial property legislation to modernise its patent system, improve administrative efficiency and strengthen legal certainty for applicants and rights holders.
Mexico Introduces Reforms to Industrial Property Law
Mexico has enacted significant amendments to its Federal Law for the Protection of Industrial Property (LFPPI), with a reform decree published on 3 April 2026. The changes are intended to modernise the country's patent system, strengthen the recognition and protection of inventors' rights, and align national procedures more closely with international practice.
Key Changes Overview
Legal Provision | Alteration |
|---|---|
Patent validity | New post-grant invalidation procedures provide clearer mechanisms for challenging improperly granted patents. |
Inventor rights | Enhanced recognition and protection of inventors' rights in both patent applications and granted patents. |
Priority claims | Restoration of Paris Convention priority rights is available within two months after the standard 12-month filing deadline. |
Provisional applications | Introduction of provisional patent applications enables applicants to secure an early filing date while allowing up to 12 months to file a complete patent application. |
Patent examination | A final decision on patent must be issued within one year from the start of substantive examination. |
Administrative oversight | Specialised technical committee established to address procedural delays. |
Patent term protection | Patent term extensions may be available in specific circumstances where administrative delays reduce the effective patent term. |
Practical Impact
The reforms represent a substantial modernisation of Mexico's patent framework, providing applicants with greater flexibility and improving the efficiency of the patent system. The introduction of provisional patent applications and expanded priority restoration provisions offers additional filing options, while new examination deadlines are intended to streamline patent prosecution and reduce administrative delays.
The availability of patent term adjustment mechanisms also strengthens legal certainty for patent owners whose commercialisation efforts are affected by regulatory approval processes.
Argentina Introduces IP Fee Increases
On 18 March 2026, the National Institute of Industrial Property of Argentina (INPI) announced a significant increase of approx. 100% across most intellectual property fees, effective from 1 April 2026. The reform also introduced the “Industrial Property Tariff Unit” (UMAPI), a new tariff unit used to calculate official fees and adjust them in line with inflation.
From 1 May 2026, the UMAPI value is adjusted on a monthly basis in line with the Consumer Price Index (CPI) for the preceding month. The updated figure applies from the first day of the following month and is published on INPI’s online portal, leaving practitioners with only a limited window for planning and fee calculation.
Key Changes Overview
Legal Provision | Alteration |
|---|---|
Official fees | Approximately 100% increase in most official fees, including trademarks, patents, designs, renewals and oppositions. |
UMAPI | Introduction of the Industrial Property Tariff Unit (UMAPI) as the standard unit for calculating official industrial property fees. |
Monthly adjustments | UMAPI is updated monthly based on the CPI published by INDEC. |
Fee calculation | Official fees are converted into Argentine pesos each month reflecting the updated UMAPI value. |
The initial UMAPI value is set at one-hundredth of the official fee for a new trademark application (one class, up to 20 goods or services), equivalent to 360 Argentine pesos.
Practical Impact
The introduction of UMAPI means that official industrial property fees in Argentina will no longer remain fixed, but will instead be adjusted monthly in line with inflation. As a result, the costs associated with filing, maintaining and enforcing industrial property rights may change over time. Applicants and rights holders should monitor monthly UMAPI updates when planning new filings and managing their IP portfolios.
What This Means for IP Owners and Attorneys
Applicants with existing or planned filings in these jurisdictions may wish to review their filing and enforcement strategies in light of the recent developments.
These reforms will have practical implications for rights holders and practitioners in both jurisdictions. Argentina's new UMAPI system means that official costs will be subject to regular adjustments, while Mexico's procedural and patent reforms should improve efficiency and provide greater flexibility for applicants. As a result, IP owners and attorneys should review their filing and portfolio strategies to ensure they remain aligned with the new requirements.
