The USPTO's TESS (Trademark Electronic Search System) is free but complex. 67% of first-time users miss conflicting trademarks due to search errors. This guide shows you how to search properly.
Why Search USPTO Before Naming Your Business
Using a name that conflicts with existing US trademark = cease and desist letters, rebranding costs ($50,000+ average), potential lawsuits. Searching first prevents these problems.
Accessing TESS Database
Go to tmsearch.uspto.gov. Click "Basic Word Mark Search" for simple searches or "Structured Form Search" for advanced.
Which Search Type to Use
Basic Word Mark Search: Single word names, simple phrases. Structured Form Search: Multiple words, specific fields, date ranges. Free Form Search: Advanced boolean operators, complex queries.
How to Search Effectively
Don't just search exact name. Search variations, phonetic equivalents, translations, abbreviations.
Search Strategy
Step 1: Search exact name (e.g., "Apex Solutions"). Step 2: Search individual words separately ("Apex" AND "Solutions"). Step 3: Search phonetic equivalents ("Apeks"). Step 4: Search common misspellings. Step 5: Search within your industry class.
Critical Mistake: Searching only exact match. "Blue Ocean Consulting" might conflict with "Blueocean", "Blue Oceans", or "BlūOcean". TESS doesn't automatically show these - you must search variations.
Understanding Search Results
TESS shows: Registration number, mark name, status (live/dead), owner, filing date, registration date, goods/services description, trademark class.
Status Meanings
Live: Active trademark, full protection. Dead: Abandoned or cancelled, may be available. Pending: Application filed, not yet registered.
Trademark Classes Matter
Same name can exist in different classes. "Delta" for airlines, faucets, dental - all valid because different classes (45 total classes).
Your Industry Class
Software/SaaS: Class 9 (software products), Class 42 (services). Retail: Class 35. Restaurants: Class 43. Clothing: Class 25. Consult USPTO class finder.
What to Do With Results
No matches in your industry = probably safe to proceed (consult attorney). Exact match in your industry = choose different name. Similar name in your industry = high risk, choose different name. Match in different industry = depends on distinctiveness.
Common Search Errors
Only searching registered marks (miss pending applications). Only searching exact spelling. Not checking phonetic equivalents. Ignoring dead marks (may still block you). Not searching common abbreviations.
The Fast Method
Trademark Lens checks USPTO automatically along with state registrations, domain availability, and social handles. Results in 30 seconds vs hours of manual TESS searching.
After Your Search
Found conflicts? Choose different name. No conflicts? Consult trademark attorney before proceeding. They do comprehensive search including common law rights (unregistered users). Budget $500-1500 for professional search.
Should You Register?
Federal trademark registration costs $250-$350 per class (DIY) or $1000-2000 with attorney. Worth it if: You plan to build brand value. You'll operate in multiple states. You want to prevent others from using your name.
Action Plan: Search TESS for your name. Search variations and phonetic equivalents. Check if matches are in your industry. If clear, verify domain availability. Consult attorney before filing business or trademark.
