What Patent Assignment Involves
Assignment, under the Ley Federal de Protección a la Propiedad Industrial, is the legal transfer of ownership of a patent or patent application from one party to another.
Doesn't Renew the Patent
Assignment and renewal are separate processes — a transferred patent still needs its maintenance fees paid on schedule.
Doesn't Change the Claims
You can't use an assignment to alter the granted claims or scope of protection.

Clear, Simple Steps to Record Your Assignment

In Mexico, an assignment is only as strong as its documentation and recordal. A signed deed of assignment, properly legalised or apostilled and translated where the parties are foreign, followed by a recordal request to IMPI, is the clearest way to make sure the change of ownership is properly reflected and enforceable.

Safeguarding Your Ownership in Mexico — With Brealant by Your Side

An unrecorded change of ownership can create uncertainty about who can enforce or license the patent, and may weaken the new owner's position in a dispute before IMPI or the courts. Brealant keeps the register accurate and the new owner's rights clearly established.

Limitations

What Assignment Recordal Does Not Do

Recordal is important, but it has limits

Doesn't Validate a Bad Deal
Recordal reflects the transfer; it doesn't cure defects in the underlying commercial agreement.
Doesn't Renew the Patent
Assignment and renewal are separate processes — a transferred patent still needs its maintenance fees paid on schedule.
Doesn't Change the Claims
You can't use an assignment to alter the granted claims or scope of protection.
Retrospective Effect Is Limited
Recordal protects the new owner going forward; earlier unrecorded dealings may need separate legal advice.
Doesn't Resolve Disputes
If ownership itself is disputed, recordal won't resolve the underlying dispute.

Brealant flags any of these issues during the assignment process so nothing is missed.

What a Patent Assignment Protects

A properly recorded assignment protects

The New Owner's Rights
Clear, documented legal ownership recognised by IMPI.
Enforcement Ability
The new owner's standing to pursue infringement action based on the patent.
Deal Certainty
The commercial transaction — acquisition, restructure, or licence — that the transfer is based on.
Future Dealings
The ability to further assign, license, or use the patent as security without ownership disputes.

Brealant makes sure every assignment is properly documented so these protections are secured.

Understanding Assignment Costs in Mexico — Simplified with Brealant

Assignment costs are modest relative to the transaction they support

Official Filing Fees
IMPI charges a modest official fee per patent, in Mexican pesos, to record an assignment.

IMPI charges a modest official fee per patent, in Mexican pesos, to record an assignment.

Frequently Asked Questions

Is recording a patent assignment mandatory in Mexico?

It isn't required for the transfer to be valid between the parties, but recording it is important for the new owner to be recognised and to protect their position against third parties.

Can a patent application be assigned before it's granted?

Yes, both pending applications and granted patents can be assigned.

Does the assignment document need to be apostilled?

Foreign-executed assignment documents generally need to be apostilled or legalised, and translated into Spanish, before IMPI will record them.

Can Brealant coordinate assignments across multiple countries?

Yes, we regularly coordinate Mexican recordals alongside assignments of corresponding patents in other jurisdictions.

How long does patent assignment recordal take?

Once properly legalised documentation is filed, IMPI typically records the change of ownership within a few weeks to a couple of months.

Can a patent be licensed instead of assigned outright?

Yes, licensing keeps ownership with you while granting usage rights to another party, and recording the license with IMPI helps protect both sides' interests.

How much does it cost to record a patent assignment with IMPI?

IMPI charges an official recordal fee, plus Brealant's fixed professional fee for preparing and filing the documentation — we quote both in advance.

What documents are needed to record a patent assignment?

Typically a signed assignment agreement, apostilled or legalized as needed, a Spanish translation, and details of both parties and the patent or application involved.

Does an unrecorded assignment still transfer ownership?

It can be valid between the parties, but recording protects the new owner's position against third parties and keeps IMPI's records accurate.

Can multiple patents in a portfolio be assigned together in one filing?

Yes, a single assignment agreement can cover multiple patents or applications, which Brealant can record with IMPI together or separately as needed.
