We need to link to Quantum GIS on a major official website. My legal department asks me if "Quantum GIS" is trademarked. Is it?

    @lewis why not answering the question if you know it? – Afr Jan 31 '13 at 15:50

    Thanks Lewis, while the about page does mention the origin of the name, it currently says nothing about whether it is trademarked or not. Right? – Satri Jan 31 '13 at 16:28

  • More open source projects are registering their names to protect them, see the example of issues surrounding Firefox: en.wikipedia.org/wiki/History_of_Firefox#Naming – scw Feb 6 '13 at 20:59

Yes, QGIS is now trademarked, see https://www.qgis.org/en/site/getinvolved/governance/trademark/index.html for more details.

  • The phrase, "Quantum GIS", is not found in the US Trademark electronic search.

  • Trademark status is not mentioned on the Quantum GIS website, nor is,

  • a trademark symbol nor statement used in the documentation.

  • The OSGeo website does have two trademark-related pages, but they only mention various OSGeo and FOSS trademarks.

You might check the archives of the mailing lists, particularly the project steering committee.

Their wiki discusses how to cite the software

Cite the QGIS project in general

Because I like to encourage research, however, I take your point. My research indicates that the answer can be gleaned from the documentation.

"This document is the original user guide of the described software Quantum GIS. The software and hardware described in this document are in most cases registered trademarks and are therefore subject to the legal requirements. Quantum GIS is subject to the GNU General Public License. Find more information on the Quantum GIS Homepage"
