Legal Definition of a Patent in Mexico
A patent application under the Ley Federal de Protección a la Propiedad Industrial is a request for exclusive rights to a new invention, examined by IMPI (Instituto Mexicano de la Propiedad Industrial) before grant.
Methods of Medical Treatment
Surgical, therapeutic, and diagnostic methods for humans or animals are generally excluded, though related devices and pharmaceuticals may be patentable.
Mere Business Methods
Purely abstract business methods, plans, or schemes without a technical contribution.

Response
Once examination concludes favourably, IMPI grants the patent.
To be patentable in Mexico, an invention must be novel (not previously disclosed anywhere), involve an inventive step (not obvious to a person skilled in the art), and have industrial applicability — generally excluding pure discoveries, scientific theories, and methods of surgical or therapeutic treatment of humans or animals.
A granted Mexican patent gives you the exclusive right to make, use, and sell your invention nationally for 20 years from the filing date, letting you commercialise, license, or enforce against competitors who copy the technology.
Certain subject matter cannot be patented under Mexican law, including
Discoveries & Scientific Theories
Pure discoveries and abstract scientific or mathematical theories.
Methods of Medical Treatment
Surgical, therapeutic, and diagnostic methods for humans or animals are generally excluded, though related devices and pharmaceuticals may be patentable.
Mere Business Methods
Purely abstract business methods, plans, or schemes without a technical contribution.
Non-Novel Inventions
Anything already publicly disclosed anywhere in the world before the filing or priority date.
Obvious Variations
Inventions that don't involve an inventive step over existing technology.
IMPI examines every application to ensure it meets these patentability requirements before grant.
A granted Mexican patent protects
The Invention Itself
The specific product, process, or method described and claimed in the specification.
Exclusive Commercial Rights
Your exclusive right to make, use, sell, or import the invention in Mexico.
Licensing Opportunities
The ability to license the invention to others for royalties or other commercial terms.
Enforcement Standing
Your standing to pursue infringement action, before IMPI and the courts, against unauthorised use of the invention.
By partnering with patent experts in Mexico, you can ensure your innovation is properly protected from filing through to grant.

IMPI charges official fees at filing, on requesting or undergoing examination, and, once granted, for maintenance fees in Mexican pesos (MXN).
IMPI charges official fees at filing, on requesting or undergoing examination, and, once granted, for maintenance fees in Mexican pesos (MXN).
These costs represent a valuable investment in securing exclusive rights to your invention across Mexico.
Once granted, a patent requires ongoing maintenance fees and can be actively monitored for infringement. Brealant supports clients through renewal tracking, licensing, and enforcement, so the value of the granted patent is protected over its full 20-year term.
