|---|
| Coverage: It covers recent patents of the EPO with at least an English title and abstract. Registered members get access to the 15,000 or more most recent patents. For all languages and full details, the original EPO record is linked. | Coverage: Google indexes full text from 22 offices and bodies, including the US, Europe, Japan, China, South Korea and WIPO. Full text exists only from certain start dates per office, and Google states that coverage is not guaranteed complete. | Coverage: Questel states coverage of offices accounting for over 99.7 percent of applications, with more than 100 million patents, 17 million designs and 150 million non-patent literature records. | Coverage: The platform is built on Derwent Global Patent Data, including the Derwent World Patents Index (DWPI), where editors rewrite titles and abstracts and patents are grouped into families. |
| Search functions: Search fields are topic, country, date, inventor and applicant. It is a fast lookup for recent filings, not a classification-driven prior art tool. | Search functions: Search supports English keywords for machine-translated documents. Non-patent literature from Google Scholar and Google Books is classified with the Cooperative Patent Classification scheme for prior art work. | Search functions: Functions include similarity search, family search, saved analyses and watch alerts on competitors. An AI assistant builds queries from natural language, with synonyms and IPC classes. | Search functions: The platform offers search and analytics, with dashboards, visualisation and predictive analytics on ownership, legal status and impact. |
| Access and cost: It is free. Registration is needed to unlock all search functions, full-size images and downloads. | Access and cost: It is free and needs no account. | Access and cost: It is a commercial product. The page refers to a demo request and gives no price. | Access and cost: It is a commercial product sold to organisations. Prices are not published on the pages reviewed. |
| Intended user: Engineers and designers who want to scan recent European patent activity quickly in a technical field. | Intended user: Inventors, students and small firms performing first prior art checks. | Intended user: IP specialists, legal teams and management, with the vendor citing more than 100,000 users. | Intended user: Patent researchers, information professionals, R&D analysts and patent attorneys. |
| Limits: It does not provide claims inside the tool, legal status or family analysis. These are obtained on the EPO record. | Limits: Completeness is not guaranteed, and it has no editorial rewriting of abstracts. | Limits: Cost and training are higher than for free tools. | Limits: The cost model suits professional search teams, not occasional checks. |
