| Languages | Not stated | English and German |
| Hosting | Not stated | Web app at register.dpma.de |
| Made in | Not stated | Germany |
| 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 | German trade marks filed since 1 January 1998, registered German marks since October 1894 insofar as they were not deleted before 1 January 1995, an excerpt of rejected and withdrawn German marks, EU trade marks from the EUIPO, and WIPO international registrations where Germany or the EU is designated. The DPMA does not warrant the accuracy and completeness of the EU and international data and points to the EUIPO and WIPO databases for a full search |
| 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 | Basic, advanced and expert searches; the expert search queries register fields such as mark, type of mark, proprietor, classes, goods and services, colours and dates with comparison and proximity operators and wildcards, and figurative elements are searchable by Vienna Classification. The DPMA states that a similarity search is not possible |
| 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 | Classes and goods and services are search fields of their own, with a link to the internationally harmonised classification of goods and services |
| 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 register search and not a clearance opinion: the DPMA does not check during the application procedure whether identical or similar marks are already registered, refers to commercial providers for similarity searches, and names patent information centres that search on your behalf for a fee |
| 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 | DPMAkurier sends automated e-mails daily, weekly or monthly on new publications and register changes, monitoring by file or publication number, by name, by class, by name and class, or user-defined; registration is needed before first use, the number of monitoring searches is not limited, and the DPMA states it can be used free of charge |
| Reports and exports | Dashboards and interactive analytics in TrademarkNow, and one report for a regional or worldwide clearance search | Result lists can be configured, organised and downloaded, a register entry prints or downloads as a complete register extract, and issues of the Markenblatt trade mark journal from 1950 onwards can be downloaded |
| Integrations and API | Not stated | DPMA connectPlus gives automated online access to the register and publication data with the query options of the expert search, plus weekly data packages for trade marks, usually on Fridays; data is supplied on the basis of an agreement against payment of the marginal cost of providing it |

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.
