A prior art search Querétaro litigation counsel can rely on has to be scoped for a system unlike the US or Europe — Mexico decides both infringement and patent validity administratively, before IMPI, not in a civil court. Querétaro is the heart of Mexico’s aerospace industry and one of its densest automotive and logistics corridors, home to the Aerocluster de Querétaro, Bombardier, Safran, Aernnova and GE Aviation, and to UNAQ, the country’s aeronautical university. The patents asserted here read on aerostructures, engines, landing gear, automotive components and supply-chain systems, and they turn on documents an examiner rarely finds. PerspireIP builds the invalidity-grade prior art to challenge them.
Where a Querétaro patent dispute is actually decided
The single fact that reshapes strategy in Querétaro is that a patent fight does not start in a courtroom. Mexico runs an administrative-first system: the Mexican Institute of Industrial Property (IMPI, the Instituto Mexicano de la Propiedad Industrial) is both the office that grants a patent and the authority that decides, at first instance, whether it is infringed and whether it is valid. There is no civil patent court the way there is in the United States or Europe. An assertion against a Querétaro aerospace or automotive company is filed at IMPI, defended at IMPI and decided by IMPI.
That structure runs on the Federal Law for the Protection of Industrial Property (LFPPI), in force since 5 November 2020, which replaced the old Industrial Property Law and modernised how infringement and nullity are pleaded and proved. Because the decision-maker is an administrative authority applying documentary evidence, the prior art you put on the record — and the date you can prove for each reference — carries the case.
- IMPI — grants Mexican patents and decides infringement and nullity (invalidity) actions at first instance as an administrative authority
- Specialised IP Chamber of the TFJA (Sala Especializada en Materia de Propiedad Intelectual, Federal Court of Administrative Justice) — reviews IMPI decisions on both infringement and validity
- Collegiate Circuit Courts — hear the constitutional amparo that follows a TFJA judgment
- Substantive examination applies to Mexican patents, but the examiner’s search rarely reaches the industry literature that anticipates an aerospace or automotive claim
IMPI as the forum: how a prior art search Querétaro case is fought
Under the LFPPI, infringement and nullity are pursued as parallel administrative proceedings before IMPI. A company accused of infringement will almost always answer by seeking nullity (invalidity) of the asserted patent, and although the two actions are prosecuted separately, IMPI resolves them together in a single decision. The nullity attack is where the prior art lands: novelty and inventive step are decided on the documentary record you build, reference by reference, against the priority date the claim actually relies on.
For a Querétaro defendant this has practical consequences. There is no jury and no live claim-construction hearing in the common-law sense; the case is won on written submissions, expert declarations and the exhibits that prove what was public and when. A prior art search Querétaro counsel commissions therefore has to be litigation-grade from the first draft — charted claim by claim, each reference dated to the day it became available to the public, and mapped to the novelty and inventive-step tests IMPI applies.
Because IMPI both granted the patent and now judges its validity, the most persuasive art is precisely what the examiner never saw: technical standards, OEM disclosures and trade literature that sit outside the patent databases. Surfacing that material, and proving its date, is the difference between a nullity request that clears the patent and one that merely restates the examination file.
Review and appeal: from IMPI to the TFJA and amparo
An IMPI decision is not the end of the road, and understanding the appellate chain is part of scoping the search. A party unhappy with IMPI’s ruling on infringement or nullity can take it to the Specialised IP Chamber of the Federal Court of Administrative Justice (TFJA) — the Sala Especializada en Materia de Propiedad Intelectual — which reviews the administrative resolution. From there, a constitutional amparo can be filed and heard by the federal Collegiate Circuit Courts.
Each rung reviews the record IMPI built. The TFJA and the amparo courts do not run a fresh prior-art trial; they test whether IMPI weighed the evidence correctly. That is why the invalidity file has to be complete and correctly evidenced at the IMPI stage — a reference whose public-availability date was not properly proved below is hard to rescue on review.
For a Querétaro aerospace or automotive company facing a multi-year enforcement campaign, that means front-loading the search. We build the reference set and the dating evidence to survive not just IMPI but the Specialised IP Chamber and an amparo, so the same body of documented prior art carries through every instance without a gap appearing on appeal.
Querétaro’s aerospace base: what the asserted patents claim
Querétaro’s litigation profile is written by the industry clustered around its international airport. The Aerocluster de Querétaro gathers dozens of manufacturers, suppliers, research centres and government bodies, and the state is the country’s aerospace epicentre. Bombardier builds structures for the Global 7000; Safran produces engine components and has expanded its Querétaro hub for A330 and 787 landing gear; the Spanish firm Aernnova fabricates aerostructures — wings, stabilisers and fuselage sections; GE Aviation, Airbus, Meggitt and dozens of Tier suppliers sit alongside them.
The result is a distinctive patent mix. Asserted claims here read on turbine and engine components, landing-gear and actuation systems, composite and metallic aerostructures, machining and additive-manufacturing methods, coatings, fasteners and inspection and non-destructive-testing techniques. These inventions are anticipated in a literature the patent record barely touches — SAE aerospace standards, AS9100 quality and process documentation, OEM technical disclosures and supplier specifications, much of it public years before a priority date.
UNAQ, the Universidad Aeronáutica en Querétaro, on its campus at the airport, trains the workforce and runs applied research whose theses, reports and conference papers are a genuine local prior-art source. Whether the technology is a landing-gear assembly or a composite wing panel, the commercial question in an IMPI nullity action is the same: can the asserted claim be shown to be old?
Automotive and logistics: the second stream of Querétaro disputes
Aerospace is only half the story. Querétaro sits in the Bajío industrial corridor with more than 300 automotive companies, a deep bench of Tier-1 suppliers, and specialisms in powertrain and interior engineering, electronics and moulds — feeding assembly plants across Mexico and North America. The corridor’s logistics backbone, including inland-port and rail-freight infrastructure linking Querétaro to Guanajuato and the wider Bajío, adds a further layer of supply-chain and materials-handling technology.
The patents asserted against these companies read on automotive components and assemblies, powertrain and electrified-drivetrain systems, sensors and electronics, tooling and moulds, and warehouse, sortation and logistics automation. As in aerospace, the decisive prior art frequently lives outside patents — SAE and ISO/TS automotive standards, supplier catalogues and datasheets, OEM engineering releases and trade-press disclosures.
Much of that record is in Spanish as well as English, and it moves fast: a component or process is often disclosed in a supplier bulletin or a standard revision long before it appears in a patent filing. A Querétaro search has to reach both languages and both worlds — patent and non-patent — and pin down the exact date each reference became public, because that date is what an IMPI nullity turns on.
How PerspireIP builds a Querétaro invalidity file
Every engagement follows the same disciplined path. We map the asserted claims element by element, fix the priority date that actually governs each one, and search against that date rather than the filing date printed on the cover. For aerospace, automotive and logistics subject-matter we run patent searching alongside deep non-patent retrieval — SAE, AS9100, ISO and NOM standards, OEM disclosures, supplier catalogues, UNAQ and university research, and older Mexican, US and international patent families — dating every reference to the day it became public.

Frequently Asked Questions
Which authority decides a Querétaro patent case?
IMPI, the Mexican Institute of Industrial Property. Mexico runs an administrative-first system: IMPI is both the office that grants a patent and the authority that decides, at first instance, whether it is infringed and whether it is valid. There is no separate civil patent court as in the United States or Europe. An assertion against a Querétaro aerospace, automotive or logistics company is filed, defended and decided at IMPI under the Federal Law for the Protection of Industrial Property (LFPPI), in force since 5 November 2020. IMPI’s decision can then be reviewed by the Specialised IP Chamber of the Federal Court of Administrative Justice (TFJA) and, after that, by the Collegiate Circuit Courts through an amparo.
How is patent validity challenged in Mexico?
Through a nullity (invalidity) action before IMPI, not in a court. Under the LFPPI, infringement and nullity are pursued as parallel administrative proceedings; a company accused of infringement typically responds by seeking nullity of the asserted patent, and although the two actions are prosecuted separately, IMPI resolves them together in a single decision. Validity turns on novelty and inventive step decided on the documentary record you file. Because there is no live trial in the common-law sense, the case is won on written submissions, expert declarations and dated exhibits, which is why a litigation-grade prior art search matters so much in Querétaro.
Why does a Querétaro prior art search focus on non-patent literature?
Because Querétaro’s patents come overwhelmingly from aerospace, automotive and logistics, and inventions in those fields are frequently anticipated in the industry technical record rather than in patents. SAE aerospace standards, AS9100 process documentation, ISO/TS automotive standards, OEM technical disclosures, supplier catalogues and datasheets, and UNAQ and university research routinely disclose the relevant art years before a priority date yet never appear in the examiner’s search. Much of it is in Spanish as well as English. A Querétaro search has to reach that grey literature and prove each reference’s public-availability date, because that is where the decisive novelty and inventive-step art hides.
Can an IMPI decision be appealed?
Yes. A party unhappy with IMPI’s ruling on infringement or nullity can take it to the Specialised IP Chamber of the Federal Court of Administrative Justice (TFJA), the Sala Especializada en Materia de Propiedad Intelectual, which reviews the administrative resolution. From there a constitutional amparo can be filed and heard by the federal Collegiate Circuit Courts. Each rung reviews the record IMPI built rather than running a fresh prior-art trial, so the invalidity file must be complete and correctly evidenced at the IMPI stage. We build the reference set and dating evidence to survive IMPI, the TFJA and an amparo without a gap appearing on appeal.
