Essential Guide to Design Invalidity in Mexico
Protecting Your Position with Brealant's Expertise

What a Design Invalidity Action Is
A declaración administrativa de nulidad, under the Ley Federal de Protección a la Propiedad Industrial, is a proceeding before IMPI to invalidate a registered design that shouldn't have been granted, typically for lack of novelty.
Purpose and Function of the Action
Because IMPI examines designs substantively at grant, a nullity action generally needs to show the examiner overlooked relevant prior art or that the design fails to meet the legal requirements.
Protecting Your Position
Separately, a design lapses (caducidad) if renewal fees go unpaid — a different, non-contentious route by which a registration can cease to be in force.

Clear, Simple Steps to Challenge a Design
In Mexico, a party challenges a registered design by filing a nullity petition before IMPI, supported by prior art or other grounds. IMPI then reviews the evidence, gives the owner a chance to respond, and decides whether to uphold or invalidate the registration — understanding this sequence is the clearest way to plan a challenge.
Safeguarding Your Market Position in Mexico — With Brealant by Your Side
If a competitor's registered design is blocking your product, or you believe it was granted in error, a nullity action is the recognised route to test, and potentially remove, that registration in Mexico. Brealant assesses the merits before recommending action.
Limitations
What a Design Challenge Cannot Achieve
A challenge is a useful tool, but it has real limits
No Pre-Grant Opposition
Mexico doesn't run a pre-grant opposition process for designs; third parties may only submit observations during the two-month publication window before registration.
Burden of Proof
The party filing the nullity petition must establish credible grounds, typically prior art the examiner didn't consider.
Owner Can Respond
The design owner is given an opportunity to respond before any nullity decision is made.
Partial Outcomes
IMPI can invalidate a registration in part rather than in full, depending on the grounds upheld.
Separate From Lapse
Nullity is a contested challenge to validity; a design lapsing for unpaid renewal fees (caducidad) is an entirely separate, administrative process.
Brealant gives you a realistic view of the likely timeline and prospects before you proceed.

Frequently Asked Questions
Can I oppose a design before it registers in Mexico?
Not through a formal opposition — third parties may only submit technical observations during the two-month publication window before IMPI decides on registration.
Who can file a nullity petition against a registered design?
Any interested party can file a nullity petition, including competitors and other affected parties.
What happens if the nullity petition succeeds?
IMPI can invalidate the registration, in whole or in part, if it finds the design wasn't genuinely new when granted.
Can the design owner defend the registration?
Yes, the owner is given an opportunity to respond and submit evidence before any nullity decision is made.
How long does a design nullity action take in Mexico?
Commonly a year or more from filing to IMPI's final decision, depending on the complexity of the evidence submitted by both sides.
How much does it cost to file a design nullity petition?
Brealant quotes a fixed professional fee once we assess your grounds, in addition to any applicable IMPI fee.
Is there a deadline to file a nullity petition after a design registers?
Generally yes — nullity actions must usually be filed within 5 years of the registration becoming effective, except claims based on bad faith, which can be filed at any time.
Can IMPI's nullity decision be appealed?
Yes, either party can challenge an unfavorable decision through an administrative appeal or a further judicial nullity trial before Mexico's specialized courts.
Can a nullity action target only part of a design's protection?
Nullity generally addresses the registration's novelty as a whole, though partial outcomes are possible where a design covers multiple product variants.
What's the difference between submitting observations during publication and filing a nullity petition later?
Observations during the two-month publication window let a third party flag issues before grant; a nullity petition challenges a design after it has already registered.
