Full Comparison
| Criterion | Canadian Trademarks Database | Corsearch |
|---|---|---|
| Output | Result lists of up to 5,000 trademarks in list or grid view, a CSV export of up to 5,000 rows, and trademark details pages that print or save as PDF | Not stated |
| Hosting | Web app on ised-isde.canada.ca | Not stated |
| Made in | Canada | Not stated |
| Registers and countries covered | All active and many inactive marks applied for or registered under the current Trademarks Act or former trademark legislation, including all marks cancelled, expunged, abandoned or refused after 1979 and some before; national and international (Madrid Protocol) filings can be shown separately. The database also holds section 9 prohibited and official marks, certification marks, geographical indications and plant breeders' rights denominations | 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 |
| Word, phonetic and image search | Basic and advanced searches over 21 fields, with up to 5 criteria combined by AND, OR and NOT, wildcards for one or several characters and quotation marks for exact sequences; filters by category, by type of mark (word, design, sound, colour, 3D, scent, motion and other non-traditional types) and by status group, and figurative searches by Vienna code. The search ignores case and accents | 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 |
| Goods, services and Nice classes | Nice classification is a search field, with the 45 classes plus class 0 for goods or services not classed, and goods and services can also be searched as text | Clearance searches take goods and services, classes and jurisdictions as their criteria, and an AI Product Insights feature categorises products for filings |
| Clearance and conflict screening | A search of the register and not a clearance opinion: CIPO recommends also searching phonetic equivalents, synonyms and translations into English or French, and consulting a trademark agent or an experienced trademark searcher when a thorough search or an interpretation of the results is required | 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 |
| Watch and alerts | Not stated | 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 |
| Reports and exports | Results export as a CSV file of up to 5,000 rows and print from the browser; each trademark's details page can be printed, saved as PDF or shared, and links to its Trademarks Office and Trademarks Opposition Board documents in the Trademarks Document Retrieval Service | Dashboards and interactive analytics in TrademarkNow, and one report for a regional or worldwide clearance search |
| Integrations and API | CIPO publishes trademarks researcher datasets as CSV and TXT tables with quarterly updates, trademark records as individual XML files paired with their images, and bulk data that can be ordered. The search itself is not intended for bulk downloads, and CIPO says clients generating 1,000 or more daily accesses may be denied access | Not stated |
| AI features | No | stated Yes |
| Deployment | Browser-based | Cloud (SaaS) |
| Onboarding | Documentation and knowledge base | Not stated |

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.
