Words From The Editor

Dear Colleague,

    Please find here the E-CAero newsletter #24. Included you find a few announcements of future events organized by one of the E-CAero partners in the H2020 E-CAERO framework, the EUROTURBO association.

 

    The usual review of recently published journals and patents of interest is enriched with data from the International Journal of Turbomachinery, Propulsion and Power,  the open-access journal of EUROTURBO. 

 

    For the section "Patents of intereset", a few were about Galileo, the European Global Navigation Satellite System (GNSS).

    Galileo went live recently, a historical moment for Europe and all users across the world: improved accuracy and novel possibilities are offered. For more infos about global and regional navigational systems, have a look here. It is interesting as well to know what is EGNOS, Europe's regional satellite-based augmentation system (SBAS).

    In particular, for the use of Galileo in aviation, please consult this exhaustive online resource in this page of the European Global Navigation Satellite Systems Agency.

 

 

    Visit their website, there is a plethora of interesting articles and news about Galileo.

Patents of Interest

 

The following patents have been selected from the EPO database using the following criteria: "WORD = galileo AND WORD = satellite AND WORD = 'solar panel' AND PUA12 >= 20160101". In this case, this means all patents whose A1/A2 documents both have been published after January 1, 2016 and contain the keywords aforementioned. 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.

Many patents are related to multiple navigation systems, due to the simplicity and benefits of using multiple satellite networks based on availability, but when Galileo and EGNOS are in use, increase in accuracy are enviseageables.

 

On this topic we see many patents filed by chinese companies.

 

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.

 

 
This newsletter (as the recent ones) has been funded by the E-CAero2 (European Collaborative Dissemination of Aeronautical research and applications 2) framework.
