How to Register a Trademark in Chile: Complete Guide 2026

Registering your trademark in Chile means asking INAPI (Instituto Nacional de Propiedad Industrial — Chile's national intellectual property office) for the exclusive right to use your name, logo, or slogan in a specific category of goods or services, for a renewable 10-year term. The process takes between 6 and 12 months and moves through a formal examination, publication in the Diario Oficial (Chile's Official Gazette), an opposition period, and a substantive examination. This guide covers what can be registered, the 45 Nice classes, each stage of the process, real-world timelines, and the mistakes worth avoiding before you file your application.

What Does Registering a Trademark in Chile Mean?

Trademark registration is the administrative act by which INAPI grants you the exclusive right to use a distinctive sign — a word, logo, label, or sound — to identify goods or services in the Chilean market. Law 19.039 on Industrial Property is the legal framework that governs this right.

Without registration, your brand is exposed. Anyone can file for the same name before you do, copy your logo, or force you to rebrand after you have already built a customer base, social media presence, and revenue. Registering before you scale is the difference between building on solid ground and building on borrowed sand.

Who Can Register a Trademark in Chile?

Anyone — individuals or companies — can register a trademark in Chile regardless of nationality or country of residence. Common applicants include:

• Individuals: entrepreneurs, freelancers, and professionals with a personal brand.

• Chilean companies: SpA, Ltda., S.A., EIRL, or other corporate structures.

• Foreign applicants without Chilean residency: eligible to register, but must designate a representative with a Chilean address to receive official notices.

As an individual, you do not need to be formally operating a business in Chile to register. What matters is deciding from the outset whether ownership will be held personally or by a corporate entity — transferring a trademark after registration carries additional costs.

Types of Trademarks: What You Can Register

In Chile you can register four main types of trademark, depending on how the distinctive sign is presented:

For most entrepreneurs, the word mark is the recommended option because it protects the name in any visual presentation. If you only register a combined mark, someone else could legally use your name with a different design.

What CANNOT Be Registered

Law 19.039 (Article 20) lists the prohibitions. The most relevant include:

• Generic or descriptive terms for the product ("Bread" for a bakery, "Fast" for a delivery service).

• Country names, flags, or official coats of arms.

• Marks identical or highly similar to already-registered marks in the same class.

• Signs contrary to public order or accepted moral standards.

• Names of living individuals without their authorization.

• Protected geographical indications ("Champagne," "Peruvian Pisco").

This is one of the key reasons a preliminary search matters: many applications fail on absolute grounds that could have been identified in advance.

The 45 Nice Classes: Which One to Register In

The Nice Classification divides all goods and services in the world into 45 classes. Classes 1 through 34 cover goods; classes 35 through 45 cover services. Your trademark is only protected in the class or classes you register.

The most frequently filed classes in Chile are:

• [Class 35](/clase-niza/35): advertising, business management, retail, and e-commerce. Nearly every online store registers here.

• [Class 41](/clase-niza/41): education, training, entertainment, and events. Chosen by academies, production companies, and content creators.

• [Class 9](/clase-niza/9): software, apps, and electronic devices. Essential for SaaS products and tech businesses.

Choosing the wrong class is one of the costliest mistakes. If you sell clothing online and register only in Class 25 (clothing), you should also be in Class 35 (retail services). You can review all categories in our Nice Classes guide.

The Steps of the INAPI Registration Process

Registration moves through stages defined by law. Here is what happens at each one so you know what to expect — without turning this into a do-it-yourself manual, because every stage has deadlines and formalities where a single mistake costs you time and money.

1. Preliminary Search

Before filing, you need to confirm that the mark is available in the desired class. The search goes beyond identical names: it also checks phonetic, visual, and conceptual similarities that could cause confusion. A superficial search is the leading cause of avoidable rejections.

2. Filing the Application

The application is submitted to INAPI with the applicant's information, the sign to be registered, the selected classes, and the specific list of goods or services to be covered. Drafting the coverage description is a technical task: a poorly worded description can leave out what you actually sell or encroach on existing marks.

3. Formal Examination

INAPI reviews whether the application meets all formal requirements. If anything is missing, it issues a formal objection with a deadline to correct it. Missing that deadline is equivalent to abandoning the application.

4. Publication in the Diario Oficial

Once the formal examination is approved, the mark is published in the Diario Oficial. From that publication date, third parties have 30 days to file an opposition.

5. Opposition Period (30 Business Days)

For 30 business days, any owner of an earlier mark may oppose the registration. If an opposition is filed, it must be answered with legal arguments within the applicable deadlines. No response — or a weak one — results in the mark being rejected.

6. Substantive Examination

INAPI evaluates whether the mark meets the substantive requirements: distinctiveness, absence of legal prohibitions, and no conflict with prior marks. If issues are found, it issues an office action (observación de fondo) that must be addressed with technical arguments.

7. Decision

INAPI issues a decision accepting or rejecting the application. If accepted, it notifies the applicant of the final fee payment required.

8. Payment of Registration Fees

The final government fee must be paid within the legal deadline. Paying late causes the application to lapse — even if it had already been approved.

9. Registration Certificate

INAPI issues the official certificate confirming ownership for 10 years from the date of grant. From that moment you may exercise all registered trademark rights: use the ® symbol, pursue infringers, license, sell, or assign the mark.

Every stage has hard deadlines and technical decisions. We handle the entire process, respond to office actions and oppositions at no additional charge, and keep you informed at every milestone.

Real-World Timelines by Stage

Statutory deadlines are one thing; real-world timelines are another. Here is what applicants typically experience:

A clean application with no office actions or oppositions typically closes around the 6-month mark. One with a substantive office action or a third-party opposition can stretch to 10–12 months. Do not believe anyone who promises "30 days": the timeline depends on INAPI, not on whoever you hire.

2026 Costs: What You Pay and to Whom

The cost of registering a trademark in Chile has three components:

The UTM (Chile's monthly tax unit) is adjusted each month. That is why we quote in UTM rather than fixed peso amounts: a figure in CLP becomes outdated within weeks.

Our registration service includes the preliminary search, drafting, filing, full follow-up, responses to office actions and oppositions at no additional charge, and notifications at every stage.

The 7 Most Common Registration Mistakes

These are the recurring missteps we see in applications that come to us after an initial rejection:

1. Choosing the wrong class. Registering in a class that does not cover your actual business leaves the mark without meaningful protection.

2. Only registering the logo version. A word mark protects the name in any design; a combined mark does not.

3. Skipping the preliminary search. Filing without checking availability leads to rejections based on identical or similar existing marks.

4. Poorly drafted coverage. Generic descriptions ("various products") or copy-pasted class headings from the Nice list generate office actions.

5. Missing office action or opposition deadlines. INAPI deadlines are absolute: once they expire, there is no recourse.

6. Registering under the wrong owner. If the mark later needs to be transferred to a company, that transfer carries additional costs.

7. Assuming a web domain or a business name registration protects you. They do not. Only an INAPI registration grants exclusive rights.

What to Do When You Receive an Office Action

An office action is an INAPI decision questioning whether your mark can be registered — on the grounds of similarity to an existing mark, lack of distinctiveness, or a legal prohibition. It is not a rejection; it is an invitation to defend your application with technical arguments.

Responding effectively requires comparative analysis, INAPI case precedents, and legal drafting. An improvised response or one submitted late is equivalent to abandoning the mark. At CheckMarca, this response is included in the initial fee — it is not a separate service.

What to Do When You Receive an Opposition

An opposition is filed by a third party — another company or prior mark owner — during the 30 days following publication. They claim that your mark infringes their rights. You must respond with a substantive brief, documentary evidence, and, where appropriate, a coexistence proposal.

Many oppositions are resolved through negotiation: narrowing the coverage, adding distinctive elements, or agreeing to coexist. Others proceed to a hearing before INAPI. Strategy depends on the specifics of each case, which is why there is no one-size-fits-all response.

What to Do After a Rejection

If INAPI rejects your application, two paths are available: file a motion for reconsideration before the same Director, or file an appeal before the Industrial Property Tribunal (TDPI). Deadlines are tight and arguments must be well-grounded. Appealing is not always the right move — sometimes reformulating the mark and filing a new application is the better strategy. We evaluate that decision case by case.

Once Registered: What Comes Next

Obtaining the certificate does not close the story — it opens it. Here is what follows:

• 10-year term from the date of grant, per Article 24 of Law 19.039.

• Mandatory renewal before the expiration date. If you miss the deadline, there is a 6-month grace period with a 20% monthly surcharge; after that, the mark lapses and becomes available for anyone to claim. Details in how to renew your trademark and lapsed trademark: penalties and deadlines.

• Active monitoring: reviewing Diario Oficial publications to oppose marks that encroach on your territory.

• Actual use. A registered mark that has never been used can be canceled by third parties after five years of non-use.

At /renovacion you can calculate the exact cost of renewing your trademark using the current month's UTM value.

Trademark vs. Patent vs. Trade Name

These are distinct concepts and should not be confused:

• Trademark: protects the distinctive sign — name, logo — that identifies goods or services. Managed through INAPI.

• Patent: protects a technical invention — a new product or process. Also filed with INAPI, but under a different process with different requirements.

• Trade name registered with Chile's tax authority (SII): simply the commercial name you declare when registering your business activity. It does not grant exclusive rights or protection against third parties.

Frequently Asked Questions

How long does it take to register a trademark in Chile?

Between 6 and 12 months. An application with no office actions or oppositions typically resolves around the 6-month mark. If a substantive office action or a third-party opposition arises, the process can extend to 10–12 months. The timeline is set by INAPI, not by whoever you hire.

Can I register a trademark as an individual without having a company?

Yes. You do not need a company, a business tax ID, or a formal business registration. Any adult individual can register a trademark in their own name. The important thing is to decide from the start whether ownership will be personal or held by a future company, because transferring the mark later carries additional costs.

How much does it cost to register a trademark in Chile in 2026?

The cost consists of INAPI fees (1 UTM when filing + 2 UTM when accepted, per class), Diario Oficial publication fees, and professional service fees. At CheckMarca, the service includes responses to office actions and oppositions with no additional charges. For a breakdown in current Chilean pesos, check our 2026 cost guide.

Can I register my trademark on my own through INAPI?

Legally yes, but technically it carries real risk. The preliminary search, drafting the coverage description, managing absolute deadlines, and responding to office actions or oppositions are all points where a small mistake can cost you months and money. That is why most applicants choose to work with professional support.

What happens if someone opposes my trademark?

A defense process with defined deadlines is triggered. You must respond with a legal brief and supporting documentation. Many oppositions are resolved through agreement — coexistence arrangements or narrowed coverage. Others proceed to a hearing before INAPI. At CheckMarca, this defense is included in the fee, not a separate service.

How many classes should I register in?

In every class that covers your current business and your near-term plans. An online clothing store typically needs Class 25 (goods) and Class 35 (retail services). A SaaS product typically needs Class 9 and Class 42. Registering in too few classes leaves gaps; registering in too many adds cost without meaningful protection.

Does a trademark registered in Chile protect me in other countries?

No. An INAPI registration protects only within Chilean territory. For other countries you must register with each national office, or use the international Madrid System. If your business targets Latin America or the United States, it is worth planning your international strategy from the outset.

What happens if I let my trademark expire?

You have a 6-month grace period to renew with a 20% monthly surcharge. After that period, the mark lapses and becomes free for anyone to register. Recovering it may be impossible if a third party claims it first. Details in our lapsed trademark guide.

Do I need to own the web domain before registering?

It is not a requirement, but it is advisable to secure both in parallel: the trademark through INAPI and the web domain. Having one without the other leaves you exposed. Trademark registration does not automatically give you the domain, and a domain does not give you trademark rights.

Can I register a name that is already in use in a different industry?

It depends. Trademarks are protected by class: two owners can coexist if they are in different classes and there is no risk of consumer confusion. However, if the earlier mark is well-known or the classes are closely related, INAPI may reject the application. A targeted preliminary search answers this question on a case-by-case basis.
