How to Do a Trademark Clearance Search (Step-by-Step)

What is a trademark clearance search?

A trademark clearance search is a review of existing trademarks to determine whether a proposed name is available to register and use. It looks beyond exact matches to catch confusingly similar marks — similar spellings, sounds, or meanings — within the relevant goods or services. A complete search covers the USPTO's Trademark Electronic Search System (TESS), state trademark registers, business name databases, and common-law uses such as active websites and social media. Clearance is a core part of trademark registration and, ultimately, of protecting your intellectual property, because the USPTO refuses applications that create a likelihood of confusion with an earlier mark. Since U.S. rights are largely first-to-file, an early clearance search also confirms whether someone else already holds priority.

How do you do a trademark clearance search step by step?

Running a clearance search follows four steps. First, define your mark and the exact goods or services it covers, then identify the correct International Class — for example, Class 25 for apparel, Class 35 for retail, or Class 9 for downloadable software. Second, search the USPTO database for identical and phonetically similar marks in that class and related classes. Third, expand the search to state registrations, domain names, and common-law uses to uncover unregistered but legally relevant marks. Fourth, assess the results for likelihood of confusion, weighing similarity of the marks and relatedness of the goods. Secure Mark USA provides a free trademark search to start, and a comprehensive search before you commit to a name and brand.

Why does a clearance search matter before you file?

A clearance search matters because filing without one risks a USPTO refusal, wasted fees, and rebranding costs. The $350-per-class government filing fee is non-refundable, so an application that collides with an existing mark loses both money and months of waiting. A strong search also reduces the chance of a cease-and-desist letter after you have invested in packaging, signage, and marketing. Clearance is the foundation of dependable brand protection: it connects your name to a clear path through trademark registration at the USPTO. Secure Mark USA prepares and files applications from $99 plus the $350-per-class USPTO fee, and U.S.-domiciled applicants are not required to hire an attorney to file.
