New layout (14.04.2022)

DEPATISnet will have a new look from 14 June.
In addition to the usual drop-down lists for the search, the IPC and the service, there is a context help for the available input fields in the Basic and Advanced search.
Using the result list configuration, you can now choose whether you want your results to be displayed as a matrix or as usual in table format.
Moreover, the pages have been streamlined. You will no longer find the usual buttons in the result list, the display of bibliographic data and the document display, but action menus for making your selection.

all news

You can use IPC symbols for your patent or utility model document search. The IPC search does not provide patent documents per se. If you have found a useful classification place in the IPC you can transfer this symbol by a single click on the magnifying glass icon directly into a search query in DEPATISnet. The search will open in a new window with the IPC symbol in "All IPC fields".
