Intellectual property rights policy

Valid since 14 May 2013

Welcome to Canonical's IPRights Policy. This policy is published by Canonical Limited (Canonical, we, us and our) under the Creative Commons CC-BY-SA version 3.0 UK licence.

Canonical owns and manages certain intellectual property rights in Ubuntu and other associated intellectual property (Canonical IP) and licences the use of these rights to enterprises, individuals and members of the Ubuntu community in accordance with this IPRights Policy.

Your use of Canonical IP is subject to:

• Your acceptance of this IPRights Policy;
• Your acknowledgement that Canonical IP is the exclusive property of Canonical and can only be used with Canonical's permission (which can be revoked at any time); and
• You taking all reasonable steps to ensure that Canonical IP is used in a manner that does not affect either the validity of such Canonical IP or Canonical's ownership of Canonical IP in any way; and that you will transfer any goodwill you derive from them to Canonical, if requested.

Ubuntu is a trusted open source platform. To maintain that trust we need to manage the use of Ubuntu and the components within it very carefully. This way, when people use Ubuntu, or anything bearing the Ubuntu brand, they can be assured that it will meet the standards they expect. Your continued use of Canonical IP implies your acceptance and acknowledgement of this IPRights Policy.

2. Your use of Ubuntu

• You can download, install and receive updates to Ubuntu for free.
• Ubuntu is freely available to all users for personal, or in the case of organisations, internal use. It is provided for this use without warranty. All implied warranties are disclaimed to the fullest extent permitted at law.
• You can modify Ubuntu for personal or internal use

• You can redistribute Ubuntu, but only where there has been no modification to it.
• You can redistribute Ubuntu in its unmodified form, complete with the installer images and packages provided by Canonical (this includes the publication or launch of virtual machine images).
• Any redistribution of modified versions of Ubuntu must be approved, certified or provided by Canonical if you are going to associate it with the Trademarks. Otherwise you must remove and replace the Trademarks and will need to recompile the source code to create your own binaries. This does not affect your rights under any open source licence applicable to any of the components of Ubuntu. If you need us to approve, certify or provide modified versions for redistribution you will require a licence agreement from Canonical, for which you may be required to pay. For further information, please contact us (as set out below).
• We do not recommend using modified versions of Ubuntu which are not modified in accordance with this IPRights Policy. Modified versions may be corrupted and users of such modified systems or images may find them to be inconsistent with the updates published by Canonical to its users. If they use the Trademarks, they are in contravention of this IPRights Policy. Canonical cannot guarantee the performance of such modified versions. Canonical's updates will be consistent with every version of Ubuntu approved, certified or provided by Canonical.

3. Your use of our trademarks

Canonical's Trademarks (registered in word and logo form) include:

• UBUNTU

• You can use the Trademarks, in accordance with Canonical's brand guidelines, with Canonical's permission in writing. If you require a Trademark licence, please contact us (as set out below).
• You will require Canonical's permission to use: (i) any mark ending with the letters UBUNTU or BUNTU which is sufficiently similar to the Trademarks or any other confusingly similar mark, and (ii) any Trademark in a domain name or URL or for merchandising purposes.
• You cannot use the Trademarks in software titles. If you are producing software for use with or on Ubuntu you may reference Ubuntu, but must avoid: (i) any implication of endorsement, or (ii) any attempt to unfairly or confusingly capitalise on the goodwill of Canonical or Ubuntu.
• You can use the Trademarks in discussion, commentary, criticism or parody, provided that you do not imply endorsement by Canonical.
