Espacenet 1.20.1 release notes – 22 February 2021


In the Bibliographic data view, there were layout issues and Espacenet was delivering oversized drawings. These were particularly common on smaller screens such as laptops, and it made the application difficult to use at times. Espacenet now calculates the size of the drawing displayed in the Bibliographic data, Description and Claims views, so you do not need to use the scroll bars. You can now adjust the width of the result list and collapse it, a feature that is particularly useful in the case of tablet-sized devices. In the collapsed view, you can still use the keyboard navigation: use the up and down arrow or "n" and "p" keys (i.e. next and previous) to navigate between results. You can also adjust the drawing width to allow you to focus on other parts.

If necessary, you can reset the screen layout in My Espacenet (My settings) if you find it difficult to operate the system with the default layout adjustments rendered by the application.

Stability and scrolling on mobile devices has been improved: the interaction is now smoother (e.g. headers no longer disappear or bounce up and down).

Document pane

Sometimes xml tags appeared in the Bibliographic data view. This has been fixed.

In addition to claims as originally filed, Espacenet displays a tree showing the interdependency between the claims. A bug meant that it was only possible to render the claims tree in English. Now this also works in French and German, as originally intended.

In the Description view, paragraphs and claims were being misrepresented and this has now been improved.  Much of the historical text in Espacenet is derived from OCR and it is sometimes difficult to determine the quality of the claim and paragraph numbering. These numbers are now often only displayed when they are likely to be reliable. Please remember that the OCRed text in the Description and Claims views is there to help you to find relevant data, but you should check the Original document view (document in pdf format) e.g. when making citations as it is the only truly reliable source of information.

Browsing the Citations table was cumbersome especially on small devices, owing to the large white spaces and very high rows. This was aggravated by the fact that non‑patent literature citations do not have a publication number. So, the sorting order of the columns has been changed (showing the Citation origin first) and rows with many entries are collapsed by default (you can expand them if necessary).

Filters and statistics

In the past, the Filters function failed when there was only one document in the result list. This has been resolved.

This release also includes other improvements that are not visible to the user. These improvements are not mentioned here.
