Trademark Search & Monitoring

Tools and APIs that search official trademark registers such as USPTO, EUIPO, WIPO and UKIPO, screen a proposed name or logo for conflicts with existing marks, and watch the registers for new filings that come too close. Every tool below is measured against the same criteria, in the same order. The subject is the trademark register and not search visibility: keyword research and rank tracking sit under SEO Tools, and a search result here is research for a decision and not legal advice.
