We at the Leosac project love it when people talk about Leosac, build businesses around Leosac, and create products and services that make life better for Leosac users and developers.

What is a trademark?
According to the United States Patent and Trademark Office, “a trademark is a word, phrase, symbol or design, or a combination of words, phrases, symbols or designs, that identifies and distinguishes the source of the goods of one party from those of others. ”
Is the Leosac name trademarked?
Yes, the name is trademarked by Leosac SAS.
Is the Leosac logo trademarked?
Yes, the logo is trademarked by Leosac SAS.
Why aren’t the logo and name covered by the AGPL?
If Leosac is free and open source, why does it need to protect its trademarks?
Trademarks protect the work of the project and the individuals contributing to it by preventing the exploitation of the good name of Leosac by other people or organizations. The trademark also prevents confusion of other organizations or companies with Leosac or Leosac SAS.
The name and logo are very different than the Leosac codebase, which is freely available for you to inspect, modify and redistribute under the terms of the GNU Affero General Public License (AGPL).
Would copyright protect the Leosac name?
No. Copyright is used for literary or creative works (including code) but is never used to protect names.
Can I transliterate “Leosac”?
In no case should the word Leosac™ be transliterated using the local language glyphs or alphabet. A Leosac logo may never use Leosac transliterated. However, in text you may make a pronunciation guide for users of the local language. On websites where the primary language does not use Latin characters, in the text of content items that use Leosac descriptively, transliteration may be used, but this must be accompanied by a disclaimer acknowledging Leosac SAS as the trademark holder and with the correct form of the name. Typically this would be in the footer of a site.
Do I have to put the trademark symbol every time I write the word “Leosac”?
No, you only need to do so in the first prominent use.
