Written by 弁理士 杉浦健文 | 2026/05/23

For professionals responsible for patent filing, registration, and enforcement in Mexico, this seminar will provide a systematic overview of patent practice in this region—which boasts the third-largest economy in North America and serves as a major hub for Japanese automotive and electronics manufacturers—centered on the 2020 LFPPI (Federal Law on the Protection of Industrial Property). Topics will include IMPI (Mexican Institute of Industrial Property) procedures, PCT national phase entry (30 months), patent term adjustment (PTA) introduced under the USMCA, the pharmaceutical linkage system,PPH strategies, and enforcement of rights before the Federal Administrative Court—all within the context of North America’s third-largest economy and a major hub for Japanese automotive and electronics manufacturers.

Key Points of This Article

  • Mexico modernized its system to comply with the USMCA through the 2020 LFPPI (New Industrial Property Law)
  • Three types of protection: Patents (20 years), Utility Models (15 years), and Designs (up to 25 years, renewable five times for 5 years each)
  • PCT member since 1995. Japanese companies have a 30-month grace period for PCT national phase entry
  • Key USMCA-related reforms: Patent Term Adjustment (PTA) and the pharmaceutical linkage system
  • Foreign applicants must appoint a local agent
  • No request for examination required (substantive examination begins automatically)—differing from Japan, the U.S., and Europe
  • Enforcement follows a three-tier system: IMPI administrative proceedings + Federal Administrative Court + Federal Circuit Court

1. Executive Summary

The Mexican patent system is a statutory framework centered on the LFPPI (new law enacted in 2020), with the LFPPI Reglamento and IMPI examination guidelines governing applications, examination, and disputes. It has been significantly modernized in response to the USMCA, and is characterized by the introduction of the "Patent Term Adjustment (PTA)" system.

Four Key Points to Keep in Mind in Mexican Patent Practice

  1. Select from three types of protection (patent, utility model, design) based on technical characteristics
  2. Government fees are denominated in MXN. Application fee is approximately MXN 4,000 (about 30,000 yen)
  3. No request for examination required—substantive examination begins automatically after filing (unlike in Japan, the U.S., and Europe)
  4. Enforcement follows a three-tier system: IMPI → TFJA → Federal Circuit Court

2. Basic Structure of the System and Legal Sources

The "primary law" of the Mexican patent system is the LFPPI (effective July 5, 2020), which completely replaced the former LPI of 1991. The patent provisions are set forth in Título Tercero (Title III).The core provisions include novelty (§47), inventive step (§48), industrial applicability (§49), exclusions from patentability (§47), application procedures (§§43-103), patent term compensation (§126), and compulsory licenses.

Role of the IMPI (same as for trademarks)

IMPI is responsible for patent examination and registration, just as it is for trademarks. It operates the PASE electronic filing system. Spanish is the mandatory language.

3. Three Types of Protection (Patents, Utility Models, and Designs)

Item Patent (Patente) Utility Model (Modelo de Utilidad) Industrial Design (Diseño Industrial)
Subject MatterTechnical InventionsMinor Inventions (Utility Models)Design
Inventive StepRequiredNot required (novelty only)Originality Required
Term of Protection20 years from the filing date15 years (non-renewable)Up to 25 years (5-year renewals, up to 5 times)

4. Application Procedures and Required Documents

Item Direct Application Paris Convention Priority Via PCT
Application DeadlineAnytime12 months from the Japanese filing date30 months from the priority date
LanguageSpanishSpanishSpanish translation required

Required documents

  • Application (Solicitud): Spanish, IMPI PASE
  • Specification, Claims, Abstract, Drawings: Spanish
  • POA: Simplified POA acceptable (notarization not required)
  • Priority Documents: If claiming Paris Convention priority, must be submitted within 3 months of the filing date
  • Assignment Deed: If the inventor and the applicant are different

5. Standard Process and Timeline

① Filing (IMPI PASE) ② Formal examination ③ Publication after
18 months
④ Substantive examination begins automatically ⑤ Response to Office Action (2 months) ⑥ Grant and registration

Timeframe: Approximately 4–6 years from filing to registration in smooth cases. Can be shortened to 2–3 years by utilizing the JPO-IMPI PPH.

6. Estimated Government Fees

Item Fee (MXN) Conversion to Japanese Yen
Application Fee (Patent)MXN 4,000Approx. 30,000 yen
Application fee (utility model)MXN 1,250Approx. 9,500 yen
Claim surcharge (more than 11 claims)MXN 200 per claimApprox. 1,500 yen/claim
Registration feeMXN 500Approx. 3,800 yen
Annual fee (5th year)MXN 600Approx. 4,500 yen
Pension (10th year)MXN 2,200Approx. 16,800 yen
Pension (15th year)MXN 4,500Approx. 34,500 yen
Pension (20th year)MXN 7,500Approx. 57,500 yen

7. Patent Requirements and Specific Provisions

Basic Requirements

  • Novelty (§47)—Worldwide prior art standard, 12-month grace period
  • Invention (Section 48)—Not obvious to a person skilled in the art
  • Industrial Applicability (§49)—Practical Usability
  • Description Requirements—Clarity and Enforceability

Exclusions from Patentability (§47)

  • Scientific, Mathematical, and Business Methods
  • Computer programs per se
  • Diagnostic, therapeutic, and surgical methods
  • Plants and Animals (excluding biotechnology-related)
  • Discoveries of human anatomy

8. Enforcement of Rights and Response to Infringement

IMPI Administrative Procedures

IMPI Infringement Administrative Procedures

  • Injunctions (Provisional Measures)
  • Seizure and Destruction of Infringing Goods
  • Fines (up to MXN 250,000)
  • Introduction of a minimum amount for damages (40%) under the 2020 LFPPI

Pharmaceutical Linkage System

Mexico has adopted the Pharmaceutical Linkage System. When applying for drug approval with COFEPRIS (Federal Commission for the Regulation of Public Health), the application is cross-checked against the IMPI patent database, and any potential patent infringement may affect approval.

9. PCT National Phase Entry and PPH Strategy

Mexico joined the PCT in 1995. National phase entry is possible within 30 months of the priority date. By utilizing the JPO-IMPI PPH, early examination can be obtained based on claims granted in Japan.

JPO-IMPI PPH: Operational since 2011; available free of charge. Reduces processing time from the usual 4–6 years to 2–3 years.

10. PTA, Pharmaceutical Linkage, and Maintenance

The term of a patent is 20 years from the filing date. Annuities are payable annually starting from the fifth year. A six-month grace period is available for late payments.

Patent Term Adjustment (PTA/LFPPI §126)

New system in response to the USMCA

  • Effective concurrently with the 2020 LFPPI
  • Compensation for IMPI examination delays (exceeding 5 years from filing)
  • Extension based on the duration of the delay (up to the maximum delay period)

11. Differences Between the Japanese and Mexican Systems

Item Japan Mexico
Language of ApplicationJapaneseSpanish
Request for examinationRequired (within 3 years)Not required (automatic examination)
Utility Model10 years15 years (non-renewable)
Design25 years5 years × 5 renewals for a maximum of 25 years

Pharmaceutical LinkageNoneYes (COFEPRIS collaboration)

12. Practical Checklist for Japanese Companies

Pre-filing

  • Select from three protection systems based on technical characteristics
  • Ensure the quality of the Spanish specification
  • Optimize the number of claims (additional fees apply for more than 11 claims)

During Filing

  • No need to request examination—examination begins automatically after filing
  • Early examination via JPO-IMPI PPH
  • Strictly adhere to the response deadline for Office Actions (2 months)

After filing

  • Annuities are due annually starting from the 5th year
  • When infringement is discovered, IMPI administrative procedures are the most practical
  • For pharmaceuticals, ensure linkage through cooperation with COFEPRIS
  • Consider filing a PTA application in case of examination delays

Summary

The Mexican patent system is characterized by the 2020 LFPPI Act and system modernization in response to the USMCA. For Japanese companies to succeed in their patent strategies in Mexico as a manufacturing hub, it is crucial to combine the use of the JPO-IMPI PPH with efficient enforcement of rights through IMPI administrative procedures, while ensuring that the use of PTAs is not overlooked.
