Find registered marks that look like yours — something USPTO text search can’t do. Upload a logo, describe a design in plain English, or start from a brand name. Searching by name, description, or serial number is free, no signup required.
Drag an image in or click the icon to upload · PNG, JPG, SVG, or WebP up to 5MB.
Click any mark to see its closest visual matches across 950K+ registered designs.
A mark like “a J and an L with a triangle between them” files the letters as wording and the symbol as a design code. Click one to find its lookalikes.
Drop in an image and we’ll find registered marks that look like it — the same visual search a USPTO examiner can’t run on a picture. Create a free account to search by image (no credit card required).
A logo can be hard to put into words — so GleanMark gives you four ways in. Start with whatever you have: the image itself, a description, a brand, or a filing number.
Type a brand — "Pepsi", "Lacoste" — to see the design and combined (logo + words) marks whose wording matches. Open to everyone, no signup.
Enter a serial or registration number to find marks that look like that mark’s stored visual fingerprint. Great for lookalike checks off an existing filing.
Describe what the logo looks like — "a roaring lion’s head inside a circular badge" — and we match it against the USPTO’s visual classification. Handy for the letter-plus-symbol marks ordinary text search can’t express.
Drop in a logo and our visual model finds registered marks that look like it — the search a picture makes possible. Free with an account.
Every design and combined mark at the USPTO is tagged with design search codes — a six-digit system that classifies the shapes, symbols, and imagery in a logo. Traditionally you had to know the exact codes and stitch them together with Boolean operators. GleanMark removes that step.
Type a plain-English description and GleanMark maps it onto the USPTO’s visual classification, then ranks the closest matches. Or pick design codes directly if you already know them.
A mark like “a J and an L with a triangle between them” files the letters as wording and the triangle as a design code — so plain text search misses it. Describe the symbol, or upload the logo, and GleanMark finds the lookalikes.
Real feedback from trademark professionals using GleanMark
Sign off with confidence
“I use GleanMark across clearance, office action responses, and general research. What sets it apart from the other trademark tools is the depth of the record underneath GleanMark. On clearance, it surfaces the conflicting marks thoroughly and gives me enough on each one to make my own call and sign off with confidence, instead of relying on a black-box ranking. On office action responses, it brings not just the arguments but the actual evidence behind them. And for day-to-day research, I can get a straight answer on any owner, any proceeding, or any single mark in seconds.”

Game-changer
“Every time I'm vetting a new brand name, I used to spend hours Googling, checking domain availability, and then paying hundreds of dollars for a trademark clearance report that took days to come back. GleanMark lets me search 14 million trademarks, check domains, and get a real answer in seconds—for free. It's a game-changer for anyone launching a new brand or startup.”

Yes. GleanMark’s logo search finds registered trademarks that look like a design — not just ones with matching text. You can search by uploading a logo image, by describing the design in plain English, by brand name, or by an existing serial or registration number. Searching by name, description, or serial number is free with no account; uploading your own image is free with a GleanMark account.
When you upload a logo, GleanMark generates a visual fingerprint of the image and compares it against the fingerprints of hundreds of thousands of registered design and combined marks, ranking the closest visual matches. The describe-in-words lane works differently: it maps your description onto the USPTO’s official design search codes so you can find a symbol — like a triangle or a crown — even when you can’t express it as text.
Design search codes are the USPTO’s official system for classifying the visual elements in a trademark — six-digit codes that describe shapes, symbols, animals, and other imagery (for example, 26.05.21 for a specific triangle). Examiners assign them to every design and combined mark so that logos can be searched by what they depict. GleanMark lets you pick codes directly, or infers them from your plain-English description.
Searching by brand name, serial or registration number, or plain-English description is completely free and requires no account. Uploading your own logo image to run a visual match is free with a GleanMark account (no credit card required) because image search uses additional vision processing.
The USPTO’s design search requires you to already know the correct six-digit design codes and combine them with Boolean operators. GleanMark lets you skip that: upload the actual logo, describe it in plain English, or start from a brand you already know. You get ranked visual matches in seconds instead of guessing codes.
Visual search covers design marks and combined marks (a logo together with words) — the marks that carry a visual fingerprint. Standard-character wordmarks (plain text with no stylization) don’t have a visual fingerprint, so for those you’d search by name instead. The describe and design-code lanes let you reach any mark classified with the design elements you’re looking for.
