USPTO Trademark Search for Startups: A Walkthrough

If you're a founder narrowing in on a company or product name, the United States Patent and Trademark Office keeps a free, public, searchable record of every federally registered and pending trademark in the country. You do not need an account, a fee, or a lawyer to search it. You do need to know where to look and how to read what you find -- which is what this walkthrough covers.

Where to search

The USPTO's search tool is called Trademark Search, and you reach it from the USPTO's own trademark search page. It replaced the older Trademark Electronic Search System, usually shortened to TESS, which the USPTO has retired -- its search page now offers a "transitioning from TESS" handout for people arriving from the old system. If an article or forum post tells you to open TESS, it predates the change; the records are the same federal database either way.

Start a search with the exact name you're considering, typed plainly, with no special formatting.

Reading the basic search results

A basic word search returns every registered or pending mark containing that word, which for a common word can be dozens or hundreds of results. For each result that looks relevant, three fields matter most:

• Status. Live, registered marks are the ones with real, current legal force. "Dead" or "abandoned" marks were once filed but no longer carry active protection -- worth noting, but not the same risk as a live registration.
• Goods and services classification. Every trademark is registered against specific categories of goods or services (the USPTO uses numbered "classes" for this). A live trademark for the same word in an unrelated category -- say, plumbing supplies versus software -- carries much less risk to you than one registered in your own category.
• Owner and filing date. Useful context for judging how established the existing mark is, and occasionally for spotting that a mark you're worried about is actually owned by a defunct or clearly unrelated business.

Searching beyond the exact spelling

This is the step founders skip, and it's the one that matters most. Trademark conflicts are frequently found in names that sound alike or look alike, not just names that are spelled identically -- the legal question is about a likelihood of confusion, not an exact character match. A useful search pass includes:

• Common misspellings and alternate spellings of your candidate name
• Phonetic equivalents (a name that sounds the same read aloud)
• The singular and plural forms
• The name combined with common suffixes like "app," "labs," or "hq," if you're considering pairing it with one

Trademark Search supports wildcard and broader matching options for exactly this reason. If you're only ever typing the exact name once and reading the first page of results, you're seeing a fraction of what's actually relevant to your risk.

What a clean search does and doesn't tell you

If your searches come back with nothing live in a related category, that's a genuinely good sign -- it means no one has already claimed federal rights to a conflicting mark in your space. It does not mean the name is legally clear to use. Federal registration is not the only source of trademark rights in the US; a business can build enforceable rights just by using a name in commerce, without ever filing anything with the USPTO, and that kind of "common law" use won't show up in the USPTO's records at all. A clean USPTO search rules out one real category of risk. It does not rule out every category.

Where a non-lawyer's judgment should stop

You can absolutely do this search yourself, and you should -- it's free, it's public, and it takes less time than most founders assume. What you're checking for is whether something worth a second look exists at all. Deciding what a specific close result actually means for your specific plans -- whether a mark in an adjacent category creates real risk for what you're building, or whether a phonetically similar name is close enough to matter -- is a legal judgment call. That call belongs to a trademark attorney, not to a search tool, and not to this guide. Treat your own search as a first filter, not a final answer.

How this fits into choosing a domain

A trademark search is one input into a bigger decision: which domain, out of a shortlist, you actually commit to. NameBearing's $149 Domain Decision Review runs a trademark search across up to five candidate domains as one part of a ranked recommendation, alongside registration status, brand-footprint collisions, and domain history, delivered in three business days with the reasoning for why each alternative was set aside. If you want a faster, lighter first look instead, the $39 Instant Domain Snapshot covers registration status and footprint automatically, though it does not include the trademark search step.
