Cataleo does not name a winner. Both statements come from the vendors themselves.
Full Comparison
| Criterion | Corsearch | USPTO Trademark Search |
|---|---|---|
| Starting price | Not stated | Free The USPTO describes its search resources as free. A free USPTO.gov account is needed for the beta image search and custom case summaries, and for an API key. |
| API | Not stated | TSDR API for trademark case status, documents and images, with an API key tied to a USPTO.gov account |
| Hosting | Not stated | Web app at tmsearch.uspto.gov |
| Made in | Not stated | United States |
| Registers and countries covered | The vendor cites 190 searchable trademark registries and 240 jurisdictions and territories watched for new marks, within more than 1,000 trademark, company name, domain, design, pharma and common law databases | Federally registered and pending US trademarks in the USPTO database. For a comprehensive clearance the USPTO lists further sources outside the tool: the Trademark Official Gazette, state trademark and business registries, domain name registries, Madrid Monitor, WIPO's Global Brand Database and EUIPO's TMview. |
| Word, phonetic and image search | Similarity search across phonetic, semantic and visual similarity in ExaMatch and NameCheck, logo and device search through LogoCheck image recognition, and an AI query assist that turns plain language into a search query | Word searches by field tag such as CM for the combined mark, with exact phrases in quotes and regular expressions for alternative spellings and pronunciations, design search codes from the Design Search Code Manual, design searches by textual description, and a beta image search from an uploaded image for logged-in users |
| Goods, services and Nice classes | Clearance searches take goods and services, classes and jurisdictions as their criteria, and an AI Product Insights feature categorises products for filings | A coordinated class filter in expert mode and the CC field tag find marks in related international and US classes, and the Trademark ID Manual lists acceptable goods and services wording |
| Clearance and conflict screening | Screening of candidate names and clearance of registered and unregistered marks, with regional or worldwide searches combining register and common law sources into one report and Corsearch analysts reviewing and filtering the results | A search tool and not a screening: the USPTO calls its database one essential step of a clearance search, says there is no surefire way to uncover all potentially conflicting trademarks, and suggests a trademark screening service or a US-licensed attorney for an in-depth search |
| Watch and alerts | Automated Watch and analyst-reviewed Expert Watch across word and design marks in 240 jurisdictions and territories, LogoWatch for logos, a user-set similarity threshold and AI prioritisation of watch results | Status alerts come from separate USPTO services: MyUSPTO can send email updates when the status of an application changes, and Trademark Center has a docketing feature that tracks the status of applications filed through it |
| Reports and exports | Dashboards and interactive analytics in TrademarkNow, and one report for a regional or worldwide clearance search | Logged-in users can choose which sections appear on a case summary for a record and print or save it; a result opens most of the TSDR information without leaving the search system |
| Integrations and API | Not stated | TSDR API for programmatic requests for trademark case status, documents and images, requiring an API key tied to a USPTO.gov account; trademark bulk data is downloadable from the USPTO Bulk Data Storage System and further data products sit on the USPTO Open Data Portal |
| AI features | stated Yes | No |
| Deployment | Cloud (SaaS) | Browser-based |
| Onboarding | Not stated | Documentation and knowledge base, Video tutorials, Live online demos and webinars |

How we check reviews
Before sending, the author has to confirm three things: that they have used the product themselves, that they work neither for the vendor nor for a competitor, and that nobody is paying them for the review. We also ask whether the vendor invited them to write it. That answer is required, either answer is accepted, and it stays with the review.
Every review is read by a person before it appears. An email address is required and is confirmed: we send a link to it, and a review does not reach us until the author opens that link, so a review has a sender who was reachable at least once rather than being anonymous. Where what somebody writes needs backing, we ask them for evidence that they used the product, and a review that does not get it is not published. We publish positive and negative reviews alike, we pay nothing and offer nothing for a review, and we accept none that was bought or incentivised.
What we cannot do is verify a purchase. There is no shop here and no account, so whether the author really used the tool rests on their own declaration, on whatever we ask them for, and on the plausibility of what they write. We say so rather than implying a check that does not exist.
A vendor cannot buy a review, and cannot have one removed or changed because they dislike it. We remove or edit a review only if it breaks our rules or the law, for example a false statement of fact. Paid placement has no effect on which reviews appear or on any score.
