New layout for DEPATISnet - we look forward to your feedback

After the DPMA internet pages had already been given a new look some time ago, the DEPATISnet database is now following suit. The database for the search of patent publications from all over the world will be adapted to the general homepage and will be visually integrated into the modern appearance. As a user, you can still access all known links (e.g. direct links to search modes) and information as well as practical features (such as the RSS feed). In the hit list, you can now directly select whether you want to call only the first page or the entire document.
Take the opportunity to give us feedback directly in DEPATISnet. You can evaluate the usability, the presentation of the research results and the help texts and have the possibility to indicate your opinion and improvement wishes in the free text. You will find the function at the top right of the help button. We look forward to your feedback!
