About USPTO Trademark

The USPTO Trademark API, hosted on RapidAPI, provides access to trademark data from the United States Patent and Trademark Office, updated daily. It supports keyword search, availability checks, serial number search, owner search, attorney search, and search by registration or filing date, along with batch processing and pagination for handling multiple queries at once. Additional functionality includes classification code lookup, expiring trademark identification, class suggestions based on business activity, and database status information showing data freshness and record counts.

Featured endpoints include batch and single trademark search, full-text search, availability checks, and searches by owner, attorney, or serial number. Responses include details such as trademark name, serial and registration numbers, status, filing and registration dates, classification codes, owner information, and associated trademark events.

The API is intended for attorneys searching trademark information for clients, businesses checking mark availability before branding, software agencies conducting verification and investigations, researchers analyzing trademark data, and individuals checking availability before starting a new business. It is offered through RapidAPI with BASIC, PRO, ULTRA, and MEGA subscription plans.
