English translations relating to Chinese, Japanese and Korean patent specifications and claims in tree view

Up to now, due to the characters, searching Asian publications has been a very tedious and time-consuming task. For the users of the DEPATISnet database, a long-cherished wish came true on 6 March 2023. The searchable text of Japanese, Chinese and Korean publications is now available as an English translation. In the searchable text, which can be called up in the result list, a full text search is possible. This new feature not only facilitates, but also accelerates the search and improves the search results. Translations are provided using WIPO Translate, an AI-powered machine translation tool. Please note that in terms of quality, machine translations are not equivalent to professional human translations and may contain inconsistencies or errors. No warranty is given for the accuracy and quality of the translation.

In addition, you can have the claims of German patents and utility models displayed in DEPATISnet in tree view (if published on or after 02/12/2021). The tree view is called up via the bibliographic data, where you can select the option via the action menu. The following restriction applies to the display of claims in tree view: If there are no dependencies or if there is a high number of claims, the tree cannot be displayed meaningfully.
