GleanMark automatically runs phonetic, spelling, and keyword matching on every search — surfacing the same conflicts a USPTO examiner would flag. No extra steps, no separate modes.

Similarity score, TTAB involvement badge, ITU status, owner link, class pills, filing date, and a one-click “Monitor” action — all visible before you click into the detail page.
Search by trademark name, owner, attorney or law firm, goods & services description, or TTAB proceeding. Each mode returns purpose-built results — owner portfolios with filing counts, firm practice stats, G&S overlap matches, and proceeding timelines.
Every record in the USPTO trademark database is searchable — from active registrations to abandoned applications filed decades ago.
Most trademark search tools show you exact matches and stop there. GleanMark goes further — finding the marks that sound alike, look alike, and could create real conflicts.
GleanMark doesn't just match exact text. It uses phonetic algorithms and trigram similarity to surface marks that sound like yours — the same marks a USPTO examiner would flag in a Section 2(d) refusal. Search "BLEU DYMOND" and find "BLUE DIAMOND."
Every trademark filed with the USPTO since 1870 is in our database — 13.9 million records and growing. New filings, status changes, and prosecution events are synced daily from the USPTO's bulk data feeds, so you're always working with current data.
Search as many trademarks as you want, as often as you want, without creating an account. The search is always free. Advanced features like monitoring alerts, AI confusion analysis, and office action drafting are available with a paid plan.
Go beyond mark names. Search by owner name to see a company's full trademark portfolio with detailed ownership profiles. Search goods & services descriptions to find marks covering similar products. Look up law firms and attorneys specializing in trademark prosecution or litigation — with portfolio stats and client lists.
Our search is built on optimized PostgreSQL indexes with pre-computed similarity scores. Most queries return in under 250 milliseconds — 10 to 50 times faster than the USPTO's own search tool.
The Nice Classification system divides all goods and services into 45 classes. Trademarks are protected within their registered classes — two identical marks can coexist if they cover different goods or services. Browse trademarks by class to understand what's already registered in your industry.

Yes. GleanMark provides a free, unlimited trademark search engine that covers every active and historical trademark in the USPTO database. Unlike the old USPTO TESS system, GleanMark offers phonetic matching, similarity scoring, and instant filtering — all without a login.

Pay attention to the Nice Classification classes and goods/services descriptions, since trademarks are only protected within their registered categories.
The USPTO retired TESS (Trademark Electronic Search System) on November 30, 2023 and replaced it with USPTO Trademark Search at tmsearch.uspto.gov. GleanMark offers a more powerful alternative with the same complete dataset, plus phonetic matching, similarity scoring, daily updates, and instant results.
You can search the USPTO trademark database directly through GleanMark. Enter a trademark name, owner, or serial number in the search box. GleanMark queries the same official USPTO data (updated daily) and returns results in seconds with detailed status information, filing history, and related marks.
Trademark classes (officially called Nice Classification classes) are 45 categories that organize all goods and services. Classes 1–34 cover goods (like electronics, clothing, and food), and Classes 35–45 cover services (like advertising, financial services, and legal services). When you register a trademark, you must specify which classes apply to your goods or services. Two identical names can coexist if they are in different classes.
On GleanMark, a trademark search returns results in under one second. The initial search shows matching marks ranked by relevance with similarity scores. Reviewing results thoroughly — checking similar marks, examining goods/services overlap, and reading prosecution histories — typically takes 15 to 30 minutes depending on how common the name is.
No. Anyone can search for trademarks for free using GleanMark or the USPTO's own tools. However, a trademark attorney can provide a professional clearance opinion, interpret complex search results, advise on likelihood-of-confusion issues, and handle the registration process. For simple name checks, a self-service search is a good starting point.
A trademark search is a quick lookup to find existing marks that match a name. A clearance search is a more comprehensive legal analysis that evaluates the risk of using or registering a name — it includes reviewing similar marks, analyzing goods/services overlap, checking common-law uses, and assessing likelihood of confusion under the DuPont factors. GleanMark supports both with its similarity scoring and AI-powered confusion analysis.
GleanMark's database focuses on U.S. trademarks filed with the USPTO, which includes Madrid Protocol international registrations that designate the United States. For trademarks registered in other countries, you would need to search that country's trademark office or use WIPO's Global Brand Database.
