Comparison
LogoVerify vs USPTO TESS
USPTO TESS is the official, free, keyword-based trademark database from the U.S. Patent and Trademark Office. LogoVerify reads the same authoritative data and adds AI visual logo search, DuPont-based risk scoring, and plain-English verdicts — built for founders and designers, not trademark attorneys.
TL;DR
Use USPTO TESS when you need the authoritative government record or you're a trademark attorney comfortable with keyword and design-code syntax. Use LogoVerify when you're a founder, designer, or online seller who needs a fast visual + name clearance check with a plain-English verdict — typically before committing to a domain, an LLC, a design handoff, or a product listing.
Both tools draw from the same underlying USPTO data. They serve different jobs: TESS is the source of truth, LogoVerify is the clearance interface.
Feature comparison
Both tools cover the same 13M+ USPTO registered and pending marks. The difference is in how those records are searched, ranked, and explained.
| Feature | LogoVerify | USPTO TESS |
|---|---|---|
| Authoritative U.S. trademark database | Mirrors USPTO TSDR daily | Direct from USPTO |
| Free to use | 3 visual checks free (lifetime trial) | Free, government-funded |
| Visual / image similarity search | AI-powered, 13M+ marks indexed | Keyword and design-code only |
| Plain-English risk verdict | Safe / Caution / Stop with rationale | Raw record lookup |
| DuPont-based risk scoring | Per-result and overall scores | |
| Designed for non-lawyers | Founders, designers, sellers | Built for trademark attorneys |
| Modern UI / mobile-friendly | Legacy frames-based interface | |
| Search history saved to account | 30 days free, permanent on Pro | |
| Files trademarks for you | Clearance tool only — use an IP attorney to file | Filing is via TEAS, separate USPTO system |
Where each tool wins
Visual similarity search
LogoVerify embeds your uploaded logo with a vision model and runs an approximate nearest-neighbor search against pre-embedded USPTO trademark images. This catches stylized monograms, abstract symbols, and color-and-shape look-alikes that no keyword query can find.
USPTO TESS supports searching by design code — a six-digit Vienna-class-like taxonomy maintained by the USPTO (e.g. 02.01.01 for "men"). It requires the searcher to manually map their design to one or more codes, which is error-prone for non-experts. LogoVerify does this matching automatically with the vision model.
Risk scoring and plain-English verdicts
LogoVerify computes a deterministic risk score for each result based on a model derived from the DuPont factors the USPTO uses for likelihood-of-confusion analysis under Lanham Act § 2(d). The model adjusts raw visual similarity by status (registered vs abandoned), mark type (design vs word), and Nice class overlap.
TESS returns raw records. It is up to the user — typically an attorney — to evaluate likelihood of confusion. For non-lawyers, this is the single biggest source of false confidence: a clean TESS keyword result does not mean the brand is clear.
When to use TESS, not LogoVerify
TESS is the authoritative source. If you need the canonical record for a specific serial or registration number — for filing, opposition, or litigation — use TESS orTSDR directly. LogoVerify is for the clearance decision before filing, not for the filing itself.
Trademark attorneys preparing a formal opinion typically search both TESS (for completeness and authority) and a visual tool (for design-code mapping). LogoVerify fills the visual side of that workflow for solo founders who can't afford an attorney for every brand exploration.
