Patenting an invention in Argentina requires showing novelty, inventive step, and industrial applicability before the INPI (Argentina’s National Institute of Industrial Property). We explain the process, the documents, and when it makes sense to work with a patent agent.
What is an invention patent?
A patent is a title that grants its owner the exclusive right to commercially exploit a new technical solution. It does not protect abstract ideas: it protects their concrete embodiment — a device, a process, a chemical composition, an industrial method or, in certain cases, a software development with a technical effect.
In Argentina, invention patents are governed by Patent Law No. 24,481 and are prosecuted before the INPI. In exchange for the temporary monopoly, the invention is published: once the patent is granted, the knowledge becomes available to the public.
What cannot be patented includes, among other things:
- Scientific discoveries with no immediate industrial application.
- Mathematical theories, teaching methods, or rules of games.
- Plants and animals, with exceptions for microorganisms.
- Methods of surgical or therapeutic treatment of the human body.
- Inventions contrary to public order or morality.
Patentability requirements
For the INPI to grant a patent, the invention must meet three cumulative requirements:
- Novelty — the solution must not have been disclosed to the public before the filing date of the application, either in Argentina or abroad. A talk at a trade show, an academic paper, or a crowdfunding video can destroy novelty if it happens before filing.
- Inventive step (inventive activity) — the solution must not be obvious to a person skilled in the art. Combining known elements in a predictable way is not enough; it takes a technical contribution that goes beyond what the prior art already taught.
- Industrial applicability — the invention must be capable of being produced or used in any branch of economic activity. It does not need to be in mass production yet, but it must be reproducible in industry.
These three pillars are assessed during substantive examination. If any of them is not met, the application may receive an office action or be refused.
Patent, utility model, or trade secret
Not every technical development is protected the same way. Before filing, it is worth defining the strategy:
- Invention patent — for solutions that represent a significant technological leap. 20 years of protection from the filing date. A more rigorous examination. Ideal for machinery, chemical compositions, industrial processes, and developments with a high inventive level.
- Utility model — for functional improvements to known objects or tools. A lower inventiveness requirement. 10 years of protection. Useful for practical adaptations: a more ergonomic device, a simplified mechanism.
- Trade secret — involves no procedure before the INPI. The competitive advantage lasts as long as the information is not disclosed. It makes sense when the formula or process cannot be reverse-engineered and secrecy is worth more than the temporary monopoly.
Patenting means publishing; a trade secret means silence. The wrong choice can cost you exclusivity or the chance to obtain protection. At Eguía we analyze each case before filing. You can read more in our article on invention patents vs. utility models. And if you want to see concrete cases, take a look at these utility model examples.
Parts of the application
A patent application filed with the INPI includes several technical and legal documents. Each one serves a different purpose:
- Specification — describes the invention in enough detail for a technician to carry it out. It includes the technical field, the prior art, the problem it solves, and the proposed solution.
- Claims — define the exact scope of protection. They are the most sensitive part of the file: broad but solid drafting maximizes exclusivity; weak drafting leaves the patent easy to design around.
- Drawings — when the invention requires them, they accompany and clarify the description.
- Abstract — a brief summary for publication and indexing.
- Forms and fees — details of the inventor and the owner, a power of attorney if a representative is acting, and payment of the corresponding fees.
The INPI first examines the formal requirements and then the substantive ones. Office actions usually target the specification or the claims: there is a deadline to respond, and the quality of the response determines whether the application moves forward.
Step by step before the INPI
The path from idea to granted patent has clear stages. This is the usual route:
1. Prior-art search. Before drafting, it is wise to search for earlier patents and publications that could anticipate your invention. A professional search covers not only the INPI but also international databases (Espacenet, WIPO, USPTO) and technical literature.
2. Drafting the application. With the map of prior art in hand, the specification and the claims are prepared. This is where you define what is protected and what remains free for others to use. It is the most critical stage of the process.
3. Online filing. The application is filed on the INPI portal with a digital signature or registered-user credentials. From that moment you have a priority date: your place in time is secured, even though the patent has not yet been granted.
4. Substantive examination. The INPI verifies novelty, inventive step, and industrial applicability. It may issue office actions that require a technical and legal response within the statutory deadline. If they go unanswered, the application may be abandoned.
5. Publication and opposition. Once the preliminary examination has been passed, the application is published. Third parties may oppose it within the applicable period if they consider that the invention does not meet the requirements or that it affects a prior right of theirs.
6. Grant. Once any oppositions have been resolved and the final fees have been paid, the INPI grants the patent. The owner receives a certificate valid for twenty years from filing, subject to payment of annual maintenance fees (annuities).
Procedure timelines
Substantive examination before the INPI can take several years, depending on the technical complexity of the file and the agency’s workload. That doesn’t mean you are unprotected: your priority dates from the day of filing, and you can mark your product “patent pending” while the process is underway.
Key deadlines to keep in mind:
- International priority — if you plan to seek patents abroad, the Paris Convention lets you claim the Argentine filing date for 12 months in other member countries.
- PCT application — within that same 12-month period, you can file an international application that defers the decision on specific countries.
- Responses to office actions — each INPI notice comes with a strict, non-extendable deadline. If it expires without a response, the application may lapse.
- Annual maintenance fees — once the patent is granted, periodic fees must be paid to keep it in force for up to 20 years.
Costs: INPI fees and professional fees
Patenting has two cost components: the INPI’s official fees and the professional fees for drafting and prosecuting the application.
INPI fees vary by stage (filing, examination, grant, annuities). The official fee schedule is updated periodically, so it is wise to check the current amount at the time of filing. In addition to the application fees, annual maintenance fees are due once the patent is granted.
Professional fees depend on the technical complexity of the invention: the more elaborate the specification and the claims, the more drafting work is involved. At Eguía we provide a quote after an initial patentability assessment, free of charge.
Patenting without advice may seem cheaper at first, but a poorly drafted application usually ends up costing more in office actions, amendments, or refusals than one that is well prepared from the start.
Common mistakes when patenting
In decades of practice before the INPI, these are the mistakes we see most often — and the most expensive ones:
- Disclosing before filing. Showing the invention at trade shows, on social media, in papers, or in an investor pitch without a confidentiality agreement destroys novelty.
- Claims that are too narrow or too broad. The former leave protection insufficient; the latter lead to office actions or refusal for lack of support.
- An incomplete specification. If a technician cannot reproduce the invention from what is written, the INPI will issue an office action.
- Not searching the prior art. Filing without knowing the earlier patents means surprises during examination and, worse, the risk of infringing someone else’s rights.
- Choosing the wrong type of protection. Applying for an invention patent when a utility model would suffice — or vice versa — lengthens the procedure and makes the process more expensive.
- Missing response deadlines. INPI notices have strict, non-extendable deadlines. Without a response, the file is abandoned.
- Forgetting the international strategy. If your market extends beyond Argentina, the 12-month priority period goes by quickly.
Before you disclose your invention
The golden rule: nothing public before filing. Presenting at a trade show, publishing a paper, uploading a crowdfunding video, or showing the prototype without protection can destroy novelty in Argentina and in most countries around the world.
If you need to share the invention with partners, suppliers, or investors before patenting, use non-disclosure agreements (NDAs) and limit the information to the minimum necessary. Document the dates and the recipients.
In some cases it makes sense to file a provisional or priority application before a public demo, even if the final specification is refined later. The strategy depends on the commercial calendar and on how far the prototype has been developed.
When should you hire a patent agent?
You can handle the procedure without an attorney or a registered agent, but applications filed with professional assistance tend to receive fewer office actions, have better-drafted claims, and stand a greater chance of being granted with a useful scope.
Professional advice is especially advisable when:
- The invention has complex technical components or several independent claims.
- You plan to exploit the development commercially or license it to third parties.
- You need international protection in addition to protection in Argentina.
- You have already received office actions from the INPI, or a refusal you want to appeal.
- You want to assess whether a patent, a utility model, or a trade secret is the better fit.

Frequently asked questions about patents
Can I patent an idea?
Ideas in the abstract cannot be patented; their technical implementation can. If you have a developed idea — even if only in drawings or a prototype — we can assess which aspects are protectable and which are better kept secret.
How long does the patent procedure take in Argentina?
Substantive examination can take several years, but your protection runs from the day of filing. You can use the “patent pending” notice, and your priority is already secured while the INPI decides on the file.
How much does it cost to patent an invention?
It depends on the technical complexity of the invention — which affects the drafting — and on the INPI’s fees at each stage. Ask us for a quote: we price it after a free initial assessment.
Does an Argentine patent protect me in other countries?
No. Patents are territorial: a patent granted in Argentina protects you only in Argentina. For other markets, you need to file applications in each country or through the PCT, taking advantage of the 12-month Paris Convention priority period.
What happens if someone uses my patented invention?
Once the patent is granted, you can take action for infringement: a formal demand letter, preliminary injunctions and, where appropriate, a claim for damages. The scope of the action depends on what your claims cover — another reason to draft them rigorously.
Next step
Patenting well is an investment in commercial exclusivity. The sooner we assess novelty, strategy, and drafting, the more options you have before you disclose the invention or the international priority period runs out.
