15 July 2015 Intellectual property rights policy

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.

1. Summary

    You can download, install and receive updates to Ubuntu for free.
    You can modify Ubuntu for personal or internal commercial use.
You can redistribute Ubuntu, but only where there has been no modification to
it.
You can use our copyright, patent and design materials in accordance with this
IPRights Policy.
    You can be confident and can trust in the consistency of the Ubuntu experience.
    You can rely on the standard expected of Ubuntu.
Ubuntu is an aggregate work; this policy does not modify or reduce rights granted
under licences which apply to specific works in Ubuntu.

2. Relationship to other licences

Ubuntu is an aggregate work of many works, each covered by their own licence(s).
For the purposes of determining what you can do with specific works in Ubuntu,
this policy should be read together with the licence(s) of the relevant packages.
For the avoidance of doubt, where any other licence grants rights, this policy
does not modify or reduce those rights under those licences.

3. 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 make changes to Ubuntu for your own personal use or for your organisation’s
own 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.

4. Your use of our trademarks

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

    UBUNTU
    KUBUNTU
    EDUBUNTU
    XUBUNTU

    LANDSCAPE

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.
You can write articles, create websites, blogs or talk about Ubuntu, provided
that it is clear that you are in no way speaking for or on behalf of Canonical
and that you do not imply endorsement by Canonical.

Canonical reserves the right to review all use of Canonical’s Trademarks and
to object to any use that appears outside of this IPRights Policy.

5. Your use of our copyright, patent and design materials

licences therein and this IPRights Policy.

Copyright

The disk, CD, installer and system images, together with Ubuntu packages and
binary files, are in many cases copyright of Canonical (which copyright may
be distinct from the copyright in the individual components therein) and can
only be used in accordance with the copyright licences therein and this IPRights
Policy.

Patents

Canonical has made a significant investment in the Open Invention Network, defending
Linux, for the benefit of the open source ecosystem. Additionally, like many
open source projects, Canonical also protects its interests from third parties
by registering patents. You cannot use Canonical’s patented materials without
our permission.

Trade dress and look and feel

Canonical owns intellectual property rights in the trade dress and look and
feel of Ubuntu (including the Unity interface), along with various themes and

and design patents, your use of Ubuntu is subject to these rights.

6. Logo use guidelines

Canonical’s logos are presented in multiple colours and it is important that
their visual integrity be maintained. It is therefore preferable that the logos

7. Use of Canonical IP by the Ubuntu community

Ubuntu is built by Canonical and the Ubuntu community. We share access rights
owned by Canonical with the Ubuntu community for the purposes of discussion,
development and advocacy. We recognise that most of the open source discussion
and development areas are for non-commercial purposes and we therefore allow
the use of Canonical IP in this context, as long as there is no commercial use
and that the Canonical IP is used in accordance with this IPRights Policy.
