Newsletter #31

Words from the Editor

Dear Colleague,



Our association has been rather busy preparing its major event eucass 2019 in Madrid, so other activities like preparing this newsletter had to momentarily be put on the back burner. Sorry about that.



The Aerospace Europe newsletter’s primary objective is to bring to your attention

  1. Conferences that are of interest to our community
  2. Contents of the latest issues of scientific journals edited in Europe
  3. Relevant patents from the European Patent Office.

Occasionally, job offers and public policy issues will be posted.

If you hear of outstanding scientific breakthroughs or publications from other groups or from your own lab, do not fail to inform us at the special email address This email address is being protected from spambots. You need JavaScript enabled to view it.  and we'll highlight them in the forthcoming issue.

That said, this issue features four main sections:

  1. Announcement of conferences from Aerospace Europe societies and the Pegasus network
  2. The usual tables of contents of European aerospace journals ordered by disciplines in order to facilitate access to material of interest to you
  3. A sections News from Readers
  4. The section "Patents of Interest" will look at a few patents of interest published in the last 6 months on a broad array of topics

Patents of Interest

In this issue of patents of interests, we will like review recent filings relative to Perovskite

Therefore, the following patents have been selected from the EPO database using the following criteria: "PUA12 >= 20190101 and WORD=Perovskite"  and selecting a few interesting patents that could have repercussions on our field. In this case, this means all patents whose A1/A2 documents both have been published after January 1, 2019. Since patents can be filed towards different organizations, sometimes the data available in the EPO database (the version available for free online) is not the most complete. In that case an external link is used. 


How to browse the EPO patent list

There are different tools online to browse/search patents, for example google and the wipo. Here we will be using the EPO Patent information services for experts, from this address. It is possible to browse patents based on many parameters, inventor name, applicant/proprietor (usually a company), application date, etc. etc. In the future we will consider patents that have published their A1/A2 documents since the date of the last newsletter.

The definition of A1 and A2 are available here.

  • Basically when a European patent application is published together with the search report done by the agency, 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.
