Infringement Analysis in Mexico City.

A patent infringement analysis Mexico City rights holders can act on has to be scoped for one feature that sets Mexico apart from the United States and Europe — enforcement runs through an administrative authority, not a civil court, and that authority sits in Mexico City. IMPI, the Mexican Institute of Industrial Property, decides both infringement and invalidity at first instance, and its rulings are reviewed by a specialised chamber of the Federal Court of Administrative Justice before a constitutional amparo can reach the federal circuit courts. Mexico City anchors the country’s pharmaceutical, consumer-goods, telecoms and financial-services markets, and the patents asserted here read on drug formulations, connected devices, payment systems and manufactured products. Each case turns on evidence that the accused product actually practises the claim, and PerspireIP builds the claim charts and evidence-of-use that prove — or defeat — that link.

Where a patent infringement analysis Mexico City case is decided

Mexico City is where Mexican patent enforcement begins and ends. The first-instance decision-maker is not a court at all but an administrative authority: the Instituto Mexicano de la Propiedad Industrial (IMPI), headquartered in Mexico City. IMPI hears, conducts and resolves administrative proceedings for both infringement and invalidity, and it can impose sanctions, order precautionary measures and, since the 2020 reform, award damages. A patent infringement action in Mexico is filed here, before the agency that granted the right.

Review of an IMPI decision is also concentrated in the capital. A final IMPI ruling — on infringement or on validity — is challenged before the Sala Especializada en Materia de Propiedad Intelectual, the specialised intellectual-property chamber of the Tribunal Federal de Justicia Administrativa (TFJA), which has national jurisdiction and is seated in Mexico City. A judgment of that chamber can then be taken to a federal collegiate circuit court through a constitutional amparo, which examines whether the decision complies with constitutional guarantees.

Because both the deciding authority and its reviewing chamber sit in the capital, a Mexican patent dispute is, in practice, a Mexico City dispute wherever the parties are based or the goods are sold. That concentration puts a premium on getting the technical file right for a specialised audience: IMPI examiners and the TFJA’s IP magistrates see patent matters constantly and read them closely, so a claim chart that would satisfy a generalist court is not enough. The analysis has to be built to withstand review by decision-makers who understand the technology and the claim language as well as counsel does.

• IMPI (Instituto Mexicano de la Propiedad Industrial) — the administrative authority in Mexico City that grants patents and decides infringement and invalidity at first instance
• Sala Especializada en Materia de Propiedad Intelectual (TFJA) — the specialised IP chamber of the Federal Court of Administrative Justice that reviews IMPI rulings
• Federal collegiate circuit courts — hear the constitutional amparo that is the final recourse against a TFJA judgment
• COFEPRIS — the health regulator that, with IMPI, runs the pharmaceutical patent-linkage gazette

Mexico’s administrative enforcement route, not a civil court

The single fact that reshapes strategy in Mexico is the forum. Where a U.S. patentee sues in a federal district court and a European rights holder litigates before national or Unified Patent Court judges, a Mexican patentee brings the case to an administrative agency. IMPI is the front-line decision-maker, and — unlike the bifurcated systems of Germany or Poland — it decides infringement and invalidity in the same forum. An accused party defending an infringement action typically files a counter-request for invalidity, and IMPI weighs both questions.

That administrative character changes how the file is built. IMPI is a technical office, not a jury or a generalist bench, so the analysis has to speak the language of examination: precise claim construction, an element-by-element reading against the accused product, and documentary evidence the agency can weigh on the written record. Oral advocacy matters far less than a clean, complete evidentiary file lodged at the outset.

Procedure is written, adversarial and conducted in Spanish. There is no U.S.-style discovery, so a rights holder cannot compel broad document production from the accused party; the burden falls on the complainant to assemble and lodge its own proof up front. Foreign-language exhibits — datasheets, laboratory reports, technical manuals — must be filed with certified Spanish translations, and expert evidence is presented on the record rather than through live cross-examination. Mexico is a first-to-file jurisdiction whose patents run for 20 years from filing, and IMPI applies the granted claims as written.

Mexico’s obligations under the United States–Mexico–Canada Agreement (USMCA / T-MEC) underpin this framework, requiring effective civil and administrative enforcement, provisional measures and adequate remedies. The result is a system where a rights holder must decide early whether to pursue the administrative route at IMPI, a parallel civil damages claim, or both — and the infringement analysis has to be scoped to whichever track it will actually serve.

The 2020 LFPPI: what changed for patent enforcement

The governing statute is the Ley Federal de Protección a la Propiedad Industrial (LFPPI), the Federal Law for the Protection of Industrial Property, which entered into force on 5 November 2020 and replaced the previous Industrial Property Law. The reform modernised Mexican enforcement in ways that matter directly to how an infringement case is worked up.

The most consequential change is on damages. Under the LFPPI a rights holder can now claim damages of at least 40% of the commercial value of the infringing products — the so-called ‘40% rule’ set out in Article 396, measured against the public sales price of the offending goods. Just as important, damages can be pursued directly through the civil or commercial courts (federal or state) without first having to obtain a final infringement ruling from IMPI, or alternatively claimed through IMPI itself. That optionality did not exist under the old law, and it forces an early strategic choice.

The LFPPI also strengthened IMPI’s power to grant precautionary measures, to order the destruction of seized infringing goods, and to run conciliation proceedings between the parties. It broadened the toolkit for calculating and recovering compensation and clarified the interaction between the administrative infringement finding and the civil damages claim, so that a favourable IMPI determination can anchor the monetary case that follows. For rights holders that had grown used to the slower, more rigid remedies of the old law, these are meaningful upgrades.

For an infringement analysis, the practical effect is that the claim mapping now feeds two objectives at once: an administrative infringement finding at IMPI, and a monetary recovery that can be quantified against the 40% benchmark. Both rest on the same foundation — a defensible reading of the claim onto a specific, evidenced accused product — so the evidence has to be built to support the finding and the damages figure together, from day one rather than bolted on after a win on liability.

Precautionary measures and securing proof of infringement

IMPI’s precautionary powers are the pressure point of most Mexican patent disputes, and they depend entirely on the strength of the analysis behind them. On the request of a patent owner or a recorded licensee, IMPI can issue a provisional or preliminary administrative order — the functional equivalent of a preliminary injunction — to immobilise and secure the infringing products at the place where they are found, including at customs in the case of imported goods.

• Provisional injunction — IMPI can seize and immobilise the allegedly infringing goods, remove them from circulation, or halt their import, before a final ruling on the merits
• Security bond — the requesting party must post a bond fixed by IMPI to cover possible damages to the defendant if the measure proves unjustified
• The 20-day rule — once a provisional measure is executed, the plaintiff must file the formal written infringement claim within 20 days, or the measure lapses

Each of these steps is only as strong as the claim mapping that supports it. IMPI will not immobilise a competitor’s goods or stop a shipment at customs on a bare assertion; it needs a clear, element-by-element showing that the accused product plausibly reads on the asserted claim, and the plaintiff exposes itself on the bond if that showing is thin. Because the formal claim follows within 20 days, the analysis cannot be assembled after the fact — it has to exist, litigation-ready, before the provisional measure is ever requested.

Mexico City’s industries and the pharma patent-linkage gazette

Mexico City’s litigation profile is written by the industries clustered in and around the capital. As the country’s economic and financial centre, it anchors the largest concentration of pharmaceutical companies and distributors in Mexico, a dense consumer-goods and manufacturing market, the headquarters of the country’s telecoms operators, and a fast-growing financial-services and fintech sector. The patents asserted here read on drug formulations and dosage regimes, connected devices and network methods, payment and security systems, and manufactured products — and each demands that infringement be proven against a specific marketed product, not asserted in the abstract.

Pharmaceuticals carry a distinctly Mexican wrinkle: the IMPI–COFEPRIS patent-linkage system. Under Article 162 of the LFPPI, IMPI publishes a gazette (Gaceta) of in-force patents that may be relevant to allopathic medicines, coordinated with the health regulator COFEPRIS and circulated in February and August each year. When a generic applicant seeks marketing approval, the linkage system flags patents that may block or delay it — and a rigorous infringement read on the reference product’s patents is what determines whether that block holds. The gazette’s scope has widened over time, including the treatment of formulation and use-related patents, which makes an accurate claim-to-product read more decisive, not less.

The capital’s telecoms and financial sector adds a second, faster-moving stream. Mexico City hosts the headquarters of the country’s largest carriers and a growing cohort of fintech firms operating under Mexico’s fintech-specific regulation, and the disputes here touch network features, connected devices, payment rails and security methods. In these matters infringement rarely sits on a datasheet; it has to be reconstructed from product behaviour, protocol analysis and documentation, then charted against every limitation of the claim before IMPI will act on it.

Whether the technology is a polymorph, a telecoms standard-related feature, a fintech method or a consumer product, the commercial question is identical: does the accused product or process actually fall within the scope of the asserted claim? Answering it precisely is exactly what a patent infringement analysis Mexico City businesses can rely on is designed to do.
