 MOODLE TRADEMARKS POLICY
 ========================
 
-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 Moodle Trademark
+--------------------
 
-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.
+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
+their trade marks and prevent the use of confusingly similar names by
+third parties.
 
-Allowed uses
-------------
+We have created a more concise and thorough set of Trademark Guidelines
+(https://moodle.com/wp-content/uploads/2023/02/Moodle-Trademark-Guidelines-2023-4.pdf)
+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.
 
-The following uses don’t require any permission at all:
+We need to be clear about use of the word "Moodle" and how we restrict its use
+when promoting commercial Moodle™ branded services. The proper use of
+trade marks reliably assures consumers about the quality of the associated
+products or services and where they have been derived from. Because the
+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.
 
-* Referring to the software or the Moodle project.
-* Describing your own Moodle implementation (including within corporate
-  settings).
+We do all this to protect the very business model that allows us to continue
+developing various Moodle software solutions for you.
+
+Allowed uses of "Moodle"
+------------------------
+
+The following uses don't require any permission at all:
+
+* Referring to the software or the Moodle project as the "Moodle™ software"
+  or the "Moodle™ project"
+* Describing your own implementation of the Moodle™ software platform
+  (including within corporate settings).
 * Describing a Moodle-based community hub.
-* Describing some software you’ve made that integrates with Moodle
-  (eg a Moodle integration feature on another system).
+* Describing certain software you've made that integrates with Moodle™
+  branded software (e.g. a Moodle™ integration feature on another system).

+Restricted uses of "Moodle"
