When a European patent application is published together with the search report, it is known as an A1 publication. When this application is published without the search report, it is an A2 document. The search report is then published later as an A3 document. When the patent is granted, it is published as a B document.
Clicking on "In my patents list" adds the document to your "My patents list". The star appears in red as soon as the document is in the list. You can store up to 100 documents in this list. The list expires after one year of non-use. This period resets automatically each time you modify the list.
If you click on the "Register" link (where activated) for a particular country this takes you straight to the corresponding entry in the national register concerned. For EP and Euro-PCT documents, clicking on the "EP Register" button allows you to view all the information pertaining to the patent application concerned, from first publication through to grant and beyond (legal status data, patent family details, etc.) in the European Patent Register.
Although the Espacenet database is continually being expanded to include additional countries and provide more extensive coverage, we do not have all items of data for all documents. For example, we may have the bibliographic data for a particular document, but not the full text or the images of the document. In this case, the sidebar options normally used for accessing the missing data are deactivated. They are re-activated when the content becomes available.
Simply right-click on the page bookmark link and select "Add to Favorites/Bookmarks" from the context menu.
A single invention can be the subject of a patent application in many different countries. In Espacenet, these related applications are known as "corresponding documents" or "equivalents". It is these that are listed under the "Also published as" heading.
Espacenet aims to have an English-language abstract available for each set of corresponding patents (also known as "equivalents"). When a document retrieved during a search does not have an English-language abstract, but there is one available for a corresponding document, the latter is displayed.
This feature provides machine translations of English abstracts into one of the supported languages, and of non-English texts into English. The text for translation is sent to specially "trained" machine translation engines, jointly developed by the EPO and Google, where it is processed and returned to the user.
