Trademark Search: How to Check If Your Brand Name Is Available
Before investing money in a brand name, logo, or slogan, you need to verify it doesn’t conflict with existing trademarks. Filing a trademark application without a proper search is the single most expensive mistake a business owner can make — the USPTO keeps your filing fees whether your application succeeds or not.
Why a Trademark Search Matters
The USPTO will reject your trademark application if it’s “likely to cause confusion” with an existing registered mark. Confusion doesn’t require identical spelling — phonetically similar names in the same industry will also be refused. “Blu Sky” can be refused if “Blue Skye” is registered for the same type of service.
Beyond USPTO rejection, launching with a conflicting mark exposes you to trademark infringement lawsuits from existing registrants — which can force you to rebrand entirely, at enormous cost.
Three Levels of Trademark Search
Level 1: USPTO TESS Free Search
The USPTO’s Trademark Electronic Search System (TESS) is free and publicly accessible at tmsearch.uspto.gov. You can search registered and pending marks by word, design code, or owner name.
Limitation: TESS only searches federally registered marks. It won’t show state registrations or common law marks — and both can block your application or lead to legal disputes.
Level 2: State Trademark Registries
Each US state has its own trademark registry. A business that has registered its name at the state level (without a federal registration) may still have grounds to oppose your federal application if you’re operating in the same state and industry.
Level 3: Common Law Search
Common law trademark rights arise from actual use in commerce — no registration required. A business actively using a name in commerce has rights in their geographic area even without any registration. A thorough common law search covers business directories, domain registrations, social media handles, and Google search results.
How to Search TESS Effectively
A basic exact-match search isn’t enough. You need to search for:
- Phonetic equivalents: Marks that sound like yours (“Koffee” for “Coffee”)
- Plural and singular forms
- Misspellings and alternate spellings
- Design codes if you’re registering a logo
- Dead marks — cancelled or abandoned marks can still cause confusion issues
What Makes Marks “Confusingly Similar”?
USPTO examining attorneys consider several factors when assessing likelihood of confusion:
- Similarity in appearance, sound, and meaning
- Whether the goods or services are related (same or related industries)
- The channels of trade (online vs. retail stores)
- The sophistication of the buyers
- The strength of the existing mark
Two marks can be similar in appearance but coexist if the goods are completely unrelated. “Apple” computers and “Apple” records coexisted for decades with a formal agreement. However, don’t count on this approach — it requires legal negotiation and creates ongoing risk.
Free vs. Professional Trademark Search
A free search on TESS catches the obvious conflicts but misses phonetic similarity, design mark conflicts, common law marks, and state registrations. A professional comprehensive trademark search conducted by experienced case analysts covers all these angles and provides a risk assessment — telling you not just what conflicts exist, but how likely they are to block your application.
The cost of a comprehensive search is a fraction of what you’d pay if your application gets rejected or you face infringement claims after launch.
What to Do After Your Search
If your search comes back clean — file immediately. Trademark rights are priority-based in the US: whoever files first generally wins. Every day you wait is a day a competitor could file the same name.
If conflicts are found, you have three options: choose a different name, negotiate a coexistence agreement with the existing owner, or consult with a trademark professional about whether the conflict is actually blocking.
