How to Do a Free Trademark Search

On February 16, 2025 By newsroom Topic: Online Business Success

Conducting a trademark search is crucial before registering your trademark to ensure it doesn’t conflict with existing ones. The Trademark Electronic Search System (TESS) is a free tool provided by the USPTO to help you check for existing trademarks. Here’s a step-by-step guide:


1. Why Search for a Trademark?

  • Avoid Conflicts: Ensure your trademark is unique and doesn't infringe on existing ones.
  • Save Time and Money: Prevent costly rejections by verifying trademark availability upfront.
  • Legal Protection: Identify potential risks and secure your brand's identity.

2. What is TESS?

  • TESS: A search engine by the USPTO that provides access to registered trademarks and pending applications in the U.S.
  • Limitation: It doesn’t include trademarks registered outside the USPTO (e.g., common law trademarks).

Tip: For a comprehensive search, consult a trademark attorney or use additional databases.


3. Steps for a Trademark Search Using TESS

Step 1: Visit the TESS Website

Step 2: Choose a Search Option

TESS offers three search types:
1. Basic Word Mark Search: Best for simple word-based trademarks.
2. Word and/or Design Mark Search (Structured): For refined searches using filters.
3. Word and/or Design Mark Search (Free-Form): Advanced search for experienced users.


4. Basic Word Mark Search

  • Best for: Checking word-based trademarks.
  • Steps:
  • Enter the word(s) in the search bar.
  • Choose “Live” marks to filter active trademarks.
  • Submit the query and review results.
  • Example: Searching for "Digital" returns trademarks containing that word.

5. Word and/or Design Mark Search (Structured)

  • Best for: Logos or more detailed trademark searches.
  • Steps:
  • Choose specific fields (e.g., design codes, owner name).
  • Enter search terms and apply filters like "Live" marks or "Design Search Code."
  • Combine multiple fields with operators (e.g., AND, OR).
  • Review results for potential conflicts.

Pro Tip: Use the USPTO Design Search Code Manual to find codes for logo elements.


6. Word and/or Design Mark Search (Free-Form)

  • Best for: Advanced users needing granular control.
  • Steps:
  • Manually format search queries with field codes (e.g., Digital[bi] AND 010103[dc]).
  • Include operators to refine searches.
  • Submit the query and analyze results.
  • Example: Narrow down trademarks with "Digital" in the name and a star-shaped logo.

7. Additional Resources for Trademark Searches

Local State Searches

Global Search

Internet Search

  • Use Google to check for unregistered trademarks or similar brand names in use.

8. Tips for Success

  • Include Variations: Search for plural forms, misspellings, and synonyms.
  • Check Goods/Services: Ensure trademarks in related industries don’t overlap.
  • Document Findings: Save search results for reference during registration.

9. When to Consult a Professional

  • If you’re unsure about search results or the “likelihood of confusion,” hire a trademark attorney for a thorough review.

Remember: A well-conducted trademark search ensures your brand is legally protected and sets the foundation for success!
