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 which supports the freedom to use, study, modify,
|
|
share and distribute hardware designs and products based on those designs.
|
|
Version 2 of the CERN Open Hardware Licence comes in three variants: this
|
|
licence, CERN-OHL-P (permissive); and two reciprocal licences: CERN- OHL-W
|
|
(weakly reciprocal) and CERN-OHL-S (strongly reciprocal).
|
|
|
|
The CERN-OHL-P is copyright CERN 2020. Anyone is welcome to use it, in unmodified
|
|
form only.
|
|
|
|
Use of this Licence does not imply any endorsement by CERN of any Licensor
|
|
or their designs nor does it imply any involvement by CERN in their development.
|
|
|
|

|
|
include Notices.

5 DISCLAIMER AND LIABILITY
|
|
|
|
5.1 DISCLAIMER OF WARRANTY -- The Covered Source and any Products are provided
|
|
'as is' and any express or implied warranties, including, but not limited
|
|
to, implied warranties of merchantability, of satisfactory quality, non-infringement
|
|
of third party rights, and fitness for a particular purpose or use are disclaimed
|
|
in respect of any Source or Product to the maximum extent permitted by law.
|
|
The Licensor makes no representation that any Source or Product does not or
|
|
will not infringe any patent, copyright, trade secret or other proprietary
|
|
right. The entire risk as to the use, quality, and performance of any Source
|
|
or Product shall be with You and not the Licensor. This disclaimer of warranty
|
|
is an essential part of this Licence and a condition for the grant of any
|
|
rights granted under this Licence.
|
|
|
|
5.2 EXCLUSION AND LIMITATION OF LIABILITY -- The Licensor shall, to the maximum
|
|
extent permitted by law, have no liability for direct, indirect, special,
|
|
incidental, consequential, exemplary, punitive or other damages of any character
|
|
including, without limitation, procurement of substitute goods or services,
|
|
loss of use, data or profits, or business interruption, however caused and
|
|
on any theory of contract, warranty, tort (including negligence), product
|
|
liability or otherwise, arising in any way in relation to the Covered Source,
|
|
modified Covered Source and/or the Making or Conveyance of a Product, even
|
|
if advised of the possibility of such damages, and You shall hold the Licensor(s)
|
|
free and harmless from any liability, costs, damages, fees and expenses, including
|
|
claims by third parties, in relation to such use.
|
|
|
|
6 Patents
|
|
|
|
6.1 Subject to the terms and conditions of this Licence, each Licensor hereby
|
|
grants to You a perpetual, worldwide, non-exclusive, no-charge, royalty-free,
|
|
irrevocable (except as stated in this section 6, or where terminated by the
|
|
Licensor for cause) patent license to Make, have Made, use, offer to sell,
|
|
sell, import, and otherwise transfer the Covered Source and Products, where
|
|
such licence applies only to those patent claims licensable by such Licensor
|
|
that are necessarily infringed by exercising rights under the Covered Source
|
|
as Conveyed by that Licensor.
|
|
|
|
6.2 If You institute patent litigation against any entity (including a cross-claim
|
|
or counterclaim in a lawsuit) alleging that the Covered Source or a Product
|
|
constitutes direct or contributory patent infringement, or You seek any declaration
|
|
that a patent licensed to You under this Licence is invalid or unenforceable
|
|
then any rights granted to You under this Licence shall terminate as of the
|
|
date such process is initiated.
|
|
|
|
7 General
|
|
|
|
7.1 If any provisions of this Licence are or subsequently become invalid or
|
|
unenforceable for any reason, the remaining provisions shall remain effective.
|
|
|
|
7.2 You shall not use any of the name (including acronyms and abbreviations),
|
|
image, or logo by which the Licensor or CERN is known, except where needed
|
|
to comply with section 3, or where the use is otherwise allowed by law. Any
|
|
such permitted use shall be factual and shall not be made so as to suggest
|
|
any kind of endorsement or implication of involvement by the Licensor or its
|
|
personnel.
|
|
|
|
7.3 CERN may publish updated versions and variants of this Licence which it
|
|
considers to be in the spirit of this version, but may differ in detail to
|
|
address new problems or concerns. New versions will be published with a unique
|
|
version number and a variant identifier specifying the variant. If the Licensor
|
|
has specified that a given variant applies to the Covered Source without specifying
|
|
a version, You may treat that Covered Source as being released under any version
|
|
of the CERN-OHL with that variant. If no variant is specified, the Covered
|
|
Source shall be treated as being released under CERN-OHL-S. The Licensor may
|
|
also specify that the Covered Source is subject to a specific version of the
|
|
CERN-OHL or any later version in which case You may apply this or any later
|
|
version of CERN-OHL with the same variant identifier published by CERN.
|
|
|
|
7.4 This Licence shall not be enforceable except by a Licensor acting as such,
|
|
and third party beneficiary rights are specifically excluded.
