Before you register a trademark, you need to make sure it’s not already taken. If you skip this step, you could face legal trouble or lose your application altogether. That’s why knowing how to search for existing trademarks before filing is one of the most important things you can do to protect your brand.

Here’s a simple, step-by-step guide to help you do it right.

Why a Trademark Search Matters

Trademark rights are based on use—not just registration. That means someone else could already own the rights to a name or logo you want to use, even if you don’t see it on the USPTO’s website.

Stat: Nearly 50% of trademark applications are rejected or delayed due to conflicts with existing marks, according to USPTO data from 2024.

A trademark search helps you:

• Avoid lawsuits
  
  
• Save money on filing fees
  
  
• Protect your brand from confusion
  
  
• Increase your chances of registration
  
  

Step 1: Know What You’re Searching For

First, you need to clearly define what you want to protect. This could be:

• A business name
  
  
• A logo
  
  
• A slogan
  
  
• A product name
  
  

Make sure the spelling, format, and wording are exactly how you plan to use them.

Step 2: Use the USPTO’s TESS Database

The Trademark Electronic Search System (TESS) is the official government database of trademarks in the U.S.

How to Use TESS:

1. Go to www.uspto.gov
   
   
2. Click “Search our trademark database (TESS)”
   
   
3. Choose “Basic Word Mark Search” or “Structured Search”
   
   
4. Enter your proposed name or phrase
   
   
5. Look for similar marks in the same or related industries
   
   

Pro Tip: Search for alternate spellings, synonyms, and phonetic matches. “Kwik Kleen” could conflict with “Quick Clean.”

Step 3: Search State Trademark Databases

Not all trademarks are registered at the federal level. Some businesses only register at the state level, especially local or small companies.

Where to Search:

• Your state’s Secretary of State website
  
  
• State business registries
  
  

This is important if you’re planning to operate regionally or want to avoid local conflicts.

Step 4: Check Domain Names and Social Media Handles

Even if no one has registered a trademark, someone may already be using your proposed name online.

Check:

• Domain name availability (use tools like GoDaddy or Namecheap)
  
  
• Instagram, Facebook, Twitter/X, TikTok, LinkedIn handles
  
  
• Google search results
  
  

A conflicting brand with a strong online presence could still create problems, even without a registered trademark.

Step 5: Use Advanced Search Tools (or Hire a Pro)

While TESS is helpful, it’s not perfect. That’s why many businesses hire a trademark attorney or use commercial search software for comprehensive trademark searches.

What These Tools Do:

• Search for similar sounding names
  
  
• Check for logos and images
  
  
• Review global trademarks (if you’re expanding internationally)
  
  
• Analyze legal risk levels
  
  

Stat: Businesses that conduct professional trademark searches reduce the risk of rejection by over 70%, according to industry data.

Step 6: Understand the "Likelihood of Confusion" Standard

The USPTO rejects applications if the new mark is likely to confuse consumers. This doesn't mean it has to be identical—just similar enough that customers could mix them up.

Key Factors:

• Similarity of names or logos
  
  
• Related goods or services
  
  
• Strength of the existing brand
  
  
• How the marks are marketed
  
  

Even small differences may not be enough if the two marks are used in the same industry.

Step 7: Consider International Trademarks

If you plan to sell your products or services outside the U.S., check for trademarks in other countries. Each country has its own rules and databases.

Where to Look:

• WIPO Global Brand Database: www.wipo.int/branddb
  
  
• National trademark offices (EUIPO, UKIPO, etc.)
  
  

Protecting your mark globally is smart if your business will grow internationally.

Step 8: Document Your Search

If you ever face a dispute, being able to show that you did a thorough trademark search can help your case. Keep notes, screenshots, or reports of your search process.

Step 9: Get a Legal Opinion

If you find something that looks close but you're not sure if it’s a problem, talk to a trademark attorney. They can give you a legal clearance opinion—which is a professional assessment of whether your trademark is safe to use.

This step can save you thousands in legal fees later.

Final Thoughts

A trademark search isn’t just a formality—it’s your first line of defense against costly legal issues. By taking the time to research before you file, you can avoid overlapping with other brands and improve your chances of successful registration.

Protect your brand before you build it. Do the research, get expert help, and make sure your mark is uniquely yours.
