Chile Trademark Search: How to Check If a Trademark Is Available

Before filing in Chile, a proper Chile trademark search tells you whether your mark is actually available — or already registered by someone else. Here is how to check INAPI’s database, what a serious search covers, and your options if the name is taken.

Chile Trademark Search: How to Check If a Trademark Is Available

Why the Search Comes First: Chile Is First-to-File

Chile operates under a first-to-file system. With limited exceptions, trademark rights belong to whoever files first at the National Institute of Industrial Property (INAPI) — not to whoever used the brand first or owns it abroad. Registrations in the US, Europe or Asia give you no automatic protection in Chile.

This is not a theoretical risk. Two of our own cases show what happens when a foreign brand skips this step:

• AIGOSTAR, an international home-appliance manufacturer, arrived in Chile to find its trademark already registered by a third party, in bad faith. Recovering it required a nullity action before INAPI.
• AGUA MENTA, an international swimwear brand, faced the same scenario. After negotiation failed, a nullity claim was filed and won, opening the door to legal sales in Chile.

Both recovered their brands — but only after litigation that delayed their market entry (see our success stories). A trademark search done before launching detects these situations while they are still cheap to solve.

INAPI’s Public Trademark Database: What It Shows

The official Chile trademark database is public and free, maintained by INAPI at inapi.cl. An INAPI trademark search lets you look up:

• Registered trademarks and their owners.
• Pending applications, which also block later filings while in process.
• The Nice classes and goods or services each mark covers.
• The status of each record: granted, in process, rejected, expired or abandoned.

It is the natural first stop and costs nothing: if your exact name is already registered in your class, you have your answer early. The key point, however: a clean result for the exact spelling of your mark does not mean the mark is available.

A Real Search Goes Far Beyond Identical Hits

Under Article 20(h) of Chilean Trademark Law (Law No. 19,039), INAPI must refuse marks that are identical or confusingly similar — graphically or phonetically — to prior registrations or valid earlier applications for identical or related goods or services. INAPI’s guidelines and the case law of the Industrial Property Court (TDPI) apply criteria a text search cannot reproduce:

• Global appreciation: marks are compared as a whole, by overall impression, not element by element.
• Phonetic similarity: marks that sound alike can block each other even when spelled differently — dropping a final letter or an ending is not enough to differentiate two signs.
• Conceptual similarity: signs evoking the same idea or meaning may also be found confusingly similar.
• Dominant element: in mixed marks (word plus logo), the word element is generally dominant; adding a logo or descriptive term to someone else’s distinctive word rarely creates a registrable difference.

There is a second dimension: coverage. Under the principle of specialty, similar marks can coexist in unrelated fields — but INAPI and the TDPI also find relatedness across different Nice classes when goods or services share nature, purpose, sales channels or consumers. A serious search screens related classes too.

Likelihood of Confusion: The Legal Test

The legal test combines three factors: similarity between the signs, identity or relatedness of the goods or services, and the resulting risk of confusion for the average consumer. These factors are interdependent — lower similarity between products can be offset by higher similarity between signs, and vice versa. Crucially, no proof of actual confusion is required: the mere possibility is enough for refusal.

One particularity foreign applicants often miss: Chilean law also protects unregistered marks genuinely used in Chile before your filing date. A prior local user can oppose your application, or seek its nullity, without any registration of its own — a risk no register-only search will surface.

The Limits of a DIY Search

Running your own INAPI trademark search is a sensible first filter, but it has limits:

• INAPI’s public tool searches by text, so it misses phonetic near-matches and conceptual equivalents.
• Results must be filtered by legal status: expired, abandoned or rejected records are not obstacles; pending applications are.
• Judging whether classes are related requires knowing INAPI’s practice and TDPI case law, not just the Nice classification.
• Telling weak, commonly shared elements apart from genuinely distinctive ones is a legal judgment call.
• The database is in Spanish, adding another layer of risk for foreign teams.

📌 The most expensive mistake is not a bad search — it is a false sense of security from a superficial one.

What a Professional Feasibility Report Includes

At von Marttens® every registration begins with a trademark feasibility report — our written answer to the question “can this mark actually be registered in Chile?”, explained in depth (in Spanish) in our article on the informe de factibilidad. The report includes:

• An AI-assisted phonetic and graphic search of the Chilean register — technology INAPI does not offer the public.
• Filtering by class, relatedness and legal status, so you only analyze real, current risks.
• A legal opinion on distinctiveness (descriptive or generic terms face separate refusal grounds under Article 20).
• A comparative table of the closest prior marks, with owner, status and similarity.
• A conclusion and strategy: file as is, adjust the sign or coverage, or address an obstacle first.

With over 72,000 trademark applications filed in Chile in 2025 alone, the register gets more crowded every year — and so does the chance someone got there first.

If the Mark Is Available — and If It Is Taken

✅ If the search comes back clean, file promptly: every week you wait is a week someone else can claim priority. The process then follows the stages in our guide to trademark registration in Chile, and registration brings the key advantages of exclusivity for renewable 10-year periods.

If a conflicting prior mark appears, you still have options:

Choosing among these paths is where local counsel earns its place.

🧠 Checklist: Trademark Search in Chile

A trademark search in Chile is not bureaucracy; it is the cheapest insurance your brand will ever buy. AIGOSTAR and AGUA MENTA recovered their marks, but only after litigation that a timely search and early filing would have made unnecessary. Knowing where you stand before filing lets you enter the Chilean market on your own terms.
