How to Avoid Trademark Oppositions and Mistakes in Colombia 2026

Trademark oppositions are one of the most common reasons for delays or rejections before the Superintendence of Industry and Commerce (SIC).
Avoiding them requires a solid strategy and understanding of how to analyze similar trademarks before filing.

This guide explains how to prevent oppositions, analyze results in the SIPI database, and respond effectively if an opposition arises.

What is a trademark opposition?

An opposition is a legal objection filed by a third party claiming that your mark may confuse consumers or conflict with a prior registration.
It can be filed within 30 business days after your application is published.

Common causes of opposition

• Similar sound or appearance (e.g., “Nice” vs. “Nike”)
• Related Nice classes (same type of goods or services)
• Notorious or well-known brands
• Generic or descriptive names
• Incomplete product descriptions

How to avoid oppositions before filing

1. Search for prior trademarks

Use the SIPI – SIC database:
https://sipi.sic.gov.co

Check for:

• Identical or similar trademarks
• Phonetic variations
• Related Nice classes

2. Interpret the results accurately

Compare:

• How the marks sound and look
• Target audience
• Type of products or services

If there’s risk of confusion, modify your name or design.

3. Draft a precise product or service description

Avoid vague phrases.
Bad: “Clothing and accessories.”
Better: “Women’s fashion garments, sports shoes, and casual wear.”

4. Include exclusions

Add notes like:

“No claim is made to the exclusive right to use the term ‘Colombia’.”

This limits your scope and prevents unnecessary conflicts.

5. Monitor your trademark

After registration, hire trademark monitoring to detect new applications that may infringe your rights.

How to respond to an opposition

If you receive an opposition:

1. Read the argument carefully.
2. Prepare your response within 30 business days.
3. Argue distinctiveness, visual or phonetic differences, and target market divergence.

Example:
In 2024, Nike successfully opposed “Nice” for phonetic similarity, demonstrating the importance of professional review.

Frequent mistakes

• No prior search
• Copying famous brands
• Ignoring exclusions
• Late response to opposition
• Vague descriptions
