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.
|
|
|
|
|
|

5 DISCLAIMER AND LIABILITY

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.
|
|
|
|

|
|
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.
