Highlight any name and check similar EUIPO trademarks with Nice-class filters and match explanations. EUIPO Similarity Check helps trademark attorneys, brand managers, and founders quickly assess whether a name may conflict with existing EU trademarks — without leaving the page they’re on. WHAT IT DOES Select any word or phrase on a webpage, right-click, and choose “Check EUIPO similarity.” A side panel opens with ranked similar EUIPO marks. You can also type a mark directly into the panel. For each result you see: • Similarity score • Status and owner • Nice classes • Why it matched — lexical similarity, phonetic match, and class overlap • Quick links to open the mark in the web app or EUIPO eSearch Filter by minimum similarity, active vs all statuses, and optional Nice classes (for example 25 or 35) so you can focus on relevant goods and services. WHY INSTALL IT • Stay in your research flow — clear a name from Gmail, docs, marketplaces, or competitor pages without jumping between tabs • Go beyond exact-match lookups — surface lookalike and soundalike marks that a simple keyword search can miss • Understand the risk signal — explanations show why a mark ranked highly, not just a green/red flag • Work EU-first — built around EUIPO similarity search for European clearance workflows WHO IT’S FOR • Trademark attorneys and IP professionals doing EU clearance • Brand managers checking naming options before filing or launch • Founders and product teams validating EU brand names early HOW TO USE 1. Click the extension icon to open the side panel (or highlight text → right-click → Check EUIPO similarity) 2. Optionally set Nice classes and similarity threshold under Filters 3. Review ranked results and open official records for verification IMPORTANT This extension provides informational research results only. It is not legal advice and does not replace a professional trademark search or legal opinion. Always verify marks on official EUIPO sources before filing or commercial use.
