Words From The Editor
Dear Colleague,
Starting from this newsletter we will add an experimental section of patent applications recently published at the European Patent Office of interest for our readers. These selected patents could suggests certain areas of research or could show how research has found way into everyday life.
Based on the feedback received, this section will be extended and/or automatized, at the beginning it will be mostly done manually.
In the meantime, please find some info about interesting publications that have been released since newsletter #14.

Recently Published Patents of Interest
The following patents have been selected from the EPO database using the following criteria: "APP = airbus* AND PUA12 >= 20151001" and "APP = boeing* AND PUA12 >= 20151001". In this case, this means all patents whose A1/A2 documents have been published after the fist October 2015, filed by a subsidiary of the Airbus and Boeing groups. 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 (for example the third example in this list).

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.
