How to Do a Logo Trademark Search

Step 1: Search the USPTO TESS Database

The Trademark Electronic Search System (TESS) is the free official database of all federally registered trademarks and pending applications. Start here because federal registrations represent the strongest existing rights and the most likely basis for a refusal of your application. TESS offers several search options, including basic word mark searches, structured searches with field codes, and free-form searches using Boolean operators.

For logo searches, you need to search beyond just the text elements. If your logo includes a design element (a graphic symbol, icon, or stylized imagery), search using the USPTO design search codes. These codes categorize design elements by visual type: geometric shapes, animals, plants, celestial bodies, human figures, and many other categories. The USPTO Design Search Code Manual lists all available codes. Searching the relevant design codes reveals logos with similar visual elements regardless of the accompanying text.

Do not search only for exact matches. The likelihood of confusion standard considers marks that are similar in sound, appearance, meaning, or overall commercial impression. Search for phonetic equivalents, abbreviations, and variations of your mark. If your logo includes the word "Peak," also search for "Peek," "Peake," "Peaq," and similar variations. A mark does not need to be identical to block your registration.

Step 2: Search State Trademark Databases

TESS only covers federal registrations and pending applications. Many marks are registered at the state level but not federally. Each state maintains its own trademark registry, usually through the secretary of state office. While state registrations provide more limited protection than federal registrations, they still represent existing rights that could create conflicts.

Searching all 50 state databases individually is impractical for most applicants. Focus on the states where you plan to do business, the states where your direct competitors operate, and the most commercially significant states (California, New York, Texas, Florida, Illinois). Some third-party search services aggregate state trademark data into a single searchable database, making this step much more efficient.

Step 3: Search Business Name Registries

Business name registrations (LLCs, corporations, DBAs) are not trademarks, but they indicate that a business is operating under a particular name. If a business has been using a name and associated logo commercially, it has common law trademark rights even without formal registration. Searching secretary of state business entity databases helps identify these potential common law conflicts.

Focus on businesses in the same or related industries. A business name identical to yours in an unrelated field is generally not a conflict, but a similar name in the same industry signals a potential problem. Note any businesses that appear to operate in your market, as they may have common law rights that TESS does not reveal.

Step 4: Search Domain Names and Internet Presence

Many businesses operate online without formal trademark registrations. Searching domain name registrations (using WHOIS databases or registrar search tools) and conducting general internet searches reveals businesses using marks similar to yours in commerce. These businesses may have common law trademark rights based on their use, even without registration.

Search Google, social media platforms, and industry-specific directories for businesses using names or logos similar to yours. Pay special attention to businesses in your industry or related industries. A small business with no trademark registration but years of active online presence in your market can still create a conflict that affects your ability to register.

Step 5: Evaluate Likelihood of Confusion

After gathering search results, evaluate whether any discovered marks create a likelihood of confusion with yours. The USPTO applies the DuPont factors (named after the case that established them) to determine likelihood of confusion. The two most important factors are: the similarity of the marks themselves, and the similarity of the goods or services associated with the marks.

Marks that are similar in appearance, sound, meaning, or overall commercial impression and are used on related goods or services are likely to create confusion. Marks that are similar but used on completely unrelated goods are generally not in conflict. For example, a logo for a pet food company is unlikely to conflict with a similar logo for an industrial welding supply company, because no consumer would confuse the two businesses.

Other DuPont factors include the sophistication of the consumers, the channels of trade, the conditions under which purchases are made, and the strength of the existing mark. A mark that is famous (like a major brand) receives broader protection than an obscure mark. Expensive products purchased by sophisticated buyers receive less confusion protection than cheap impulse purchases, because sophisticated buyers are presumed to exercise more care in distinguishing brands.

Step 6: Consider a Professional Search

If your DIY search reveals potential conflicts or if you want greater confidence before investing in a filing, consider engaging a professional search service. Trademark attorneys and specialized search firms conduct comprehensive searches that cover federal, state, common law, and international sources. The resulting report includes legal analysis of the findings, not just a list of marks but an assessment of whether each discovered mark poses a real risk to your application.

Professional searches cost $300 to $1,500 depending on the scope and provider. This cost is a fraction of the potential loss from a rejected application ($350 or more in non-refundable fees) or from adopting a mark that triggers an infringement claim from an existing user. For marks in competitive industries or markets with many existing registrations, the professional search is a worthwhile investment in risk reduction.
