 MOODLE TRADEMARKS POLICY
 ========================

-The Moodle Trademark
--------------------
+The word "Moodle" is trademarked in many countries around the world. The word
+was originally coined as an acronym: Modular Object-Oriented Dynamic Learning
+Environment. The trademark is owned by Martin Dougiamas, Founder and Director
+of Moodle.

-The brand and word "Moodle" has trade mark protection in many countries around
-the world. Various Moodle™ trade marks are owned by either Moodle Pty Ltd or
-one of its associated entities. The law obligates trade mark owners to police

+The law obligates trademark owners to police their marks and prevent the use of
+confusingly similar names by third parties. Through this policy we’d like to
+make it clear how Moodle-related projects, organisations, and people can use
+the Moodle trademark. We’d also like to be clear about how use of the word is
+restricted when used to promote commercial Moodle services. We do this to
+protect the very business model that allows us to continue developing Moodle
+for you.

-to help you understand how to comply with Moodle's trade mark requirements.
-The Trademark Guidelines will also assist our Moodle Certified Partners and the
-community to understand some of the principles that inform Moodle's stance
-whenever potential infringement has been detected by us or our community.

-when promoting commercial Moodle™ branded services. The proper use of
-trade marks reliably assures consumers about the quality of the associated

-Moodle LMS is made available under the open source ‘GNU General Public License'
-that permits you to modify the copyrighted software, the distribution of such
-modified software in combination with Moodle trade marks can potentially
-mislead others in the community. To be clear, the GNU GPL does not include an
-implied right or licence to use Moodle's trade marks.

-We do all this to protect the very business model that allows us to continue
-developing various Moodle software solutions for you.
