CERN Open Hardware Licence Version 2 - Permissive
Preamble
CERN has developed this licence to promote collaboration among
hardware designers and to provide a legal tool for the dissemination
of hardware designs. The CERN Open Hardware Licence Version 2 is
available in two variants: Weakly Reciprocal (CERN-OHL-W) and
Permissive (CERN-OHL-P). The CERN-OHL-P is for you if you want to
maximise the ability of people to use your hardware design
including for use in commercial applications with a minimum of
obligations. It is a continuation of the CERN Open Hardware Licence
version 1 (but with a new structure) and is focused more narrowly
on the design itself and what you must do to give proper credit and
to allow others to build and modify the design.
Please see the CERN-OHL version 2 family page (www.ohwr.org/cernohl)
for more information.
Terms and conditions
1. Definitions
In this Licence, the following terms have the following meanings:
"Additive" means something you add to the Design that was not part
of it when it was first published by the Licensor.
"Design" means the design documentation for the hardware that is
licensed under this Licence, in any format or medium. It may
include both the Hardware Description and the Modifications.
"Documentation" means all the materials that are provided by the
Licensor or any Contributor to describe the Design, including
schematics, netlists, PCB layout files, bills of materials,
drawings, specifications, and the like, and also includes the
Modifications.
"Hardware" means any physical device that embodies the Design or
any part thereof, in any form.
"Hardware Description" means the files that specify the Hardware in
a form that can be read by a computer and that, when used
appropriately, can be used to fabricate Hardware, for example in
whole or in part.
"Licence" means this licence (the CERN-OHL-P).
"Licensor" means the person or entity that first publishes the
Design under the terms of this Licence.
"Modification" means any change to the Design, including changes to
the Hardware Description.
"Product" means either an unchanged Design or a Design with
Modifications, that is offered for sale, or otherwise made
available for commercial use, whether as Hardware or in other forms.
"Source" means the format of the Design that is preferred for
making Modifications, including all the files that are provided for
that purpose.
"You" means any person or entity that exercises any right under
this Licence.
2. What this Licence covers
The Licensor grants you a worldwide, royalty-free, non-exclusive,
perpetual licence to:
a) use the Design and any associated Documentation,
b) make Modifications,
c) communicate the Design and any Documentation, including by
making it available for copying and modification,
d) manufacture and distribute Hardware that implements the Design
or any part thereof,
e) sell Products, and
f) otherwise deal in the Design or any part thereof,
all in each case subject to the conditions set out in this Licence.
3. Conditions
3.1. Availability of Source
The Design and any Documentation that is made available under this
Licence must be made available in Source format. If the Design is
available in a format that is not Source, you must also make a
version of the Design in Source format available, and you must
inform others of how to obtain it.
3.2. Retention of copyright and other notices
You must retain all copyright and other notices that appear in the
Design or Documentation.
3.3. Notice of Modifications
If you make Modifications, you must include a notice in any
Distribution of the Design or Documentation, stating that
Modifications have been made, by whom, and in what they consist.
3.4. Distribution of Modifications
If you distribute any Design or Documentation, whether unchanged or
with Modifications, you must distribute it under this Licence, and
you must inform the recipient that the Design or Documentation is
licensed under this Licence.
3.5. No implicit approval
The Licensor shall not be taken to have approved any Modifications
unless the Licessor expressly approves them in writing.
4. Disclaimer of warranty
THE DESIGN AND ANY DOCUMENTATION IS PROVIDED "AS IS" AND THE
LICENSOR MAKES NO WARRANTY, EXPRESS OR IMPLIED, INCLUDING BUT NOT
LIMITED TO WARRANTIES OF MERCHANTABILITY, SATISFACTORY QUALITY,
NON-INFRINGEMENT, TITLE, AND FITNESS FOR A PARTICULAR PURPOSE. THE
DESIGN MAY CONTAIN DESIGN DEFECTS OR ERRORS THAT MAKE IT
UNSUITABLE FOR USE IN CERTAIN APPLICATIONS. THE ENTIRE RISK AS TO
ITS QUALITY AND PERFORMANCE REMAINS WITH YOU.
5. Limitation of liability
TO THE EXTENT NOT PROHIBITED BY LAW, IN NO EVENT WILL THE LICENSOR
BE LIABLE FOR ANY DAMAGES WHATSOEVER, INCLUDING WITHOUT LIMITATION
LOST PROFITS, PROCUREMENT OF SUBSTITUTE GOODS OR SERVICES, OR ANY
OTHER LOSSES ARISING OUT OF THE USE OF THE DESIGN OR ANY
DOCUMENTATION, HOWEVER CAUSED, WHETHER UNDER THEORY OF CONTRACT,
TORT (INCLUDING NEGLIGENCE), PRODUCTS LIABILITY, OR OTHERWISE,
EVEN IF ADVISED OF THE POSSIBILITY OF SUCH DAMAGES.
6. Termination
This Licence is perpetual except that if you fail to comply with
its terms, your rights under this Licence will terminate immediately.
If you bring or defend any litigation or other claim alleging that
the Design or any part thereof infringes any intellectual property
right, all your rights under this Licence granted by the Licensor
will terminate forty-five days after you bring or defend such claim.
7. General
This Licence shall be governed by the laws of the country of the
Licensor, without reference to its conflict of laws provisions.
If any part of this Licence is held to be invalid or unenforceable,
the remaining parts shall remain in full force and effect.
