The USPTO retired classic TESS, and its replacement Trademark Search system has no clean bulk API. This USPTO trademark search API fills that gap: query by word mark or US serial number and get structured JSON — mark text, owner, live/dead status, Nice classes, goods + services, and full prosecution history — built for trademark knockout and clearance searches. Screen dozens of candidate names in minutes instead of paying $199 per single-mark lookup at LegalZoom.

Why this actor (vs TrademarkVision, Corsearch, CompuMark & LegalZoom)

Most attorneys and brand teams pick this actor for the knockout stage — screening dozens of candidate names cheaply before committing to a formal clearance memo — instead of paying per-search at LegalZoom or signing an enterprise contract for early-stage screening.

Use Cases

• Trademark attorneys — bulk knockout searches before a formal clearance memo.
• Brand strategists — check 50 candidate names during a naming workshop.
• Startup founders — verify US name availability before LLC formation or domain buy.
• IP-monitoring firms — daily watch on competitor filings in a tracked Nice class.
• M&A diligence teams — pull a target's full US TM portfolio in one run.

FAQ

How do I search the USPTO trademark database? Run this actor with a word mark (searchType: "name") or a US serial number (searchType: "number"). It returns structured status, owner, classification, and dates with a live/dead flag.

What replaced TESS? The USPTO retired classic TESS in favor of its new Trademark Search system. This actor targets the current public trademark data so your queries keep working.

Is there an official USPTO trademark API? The USPTO Open Data Portal exposes some trademark data but no easy bulk search. This is a practical drop-in: clean JSON, no login, pay per result.

What's the difference between a knockout and a clearance search? A knockout is a fast exact/near-match screen of federal records; a full clearance adds phonetic and common-law review. This actor powers the knockout stage at scale.

What output formats are supported? JSON, CSV, Excel, and the Apify dataset API.
