+CERN Open Hardware Licence Version 2 - Strongly Reciprocal
|
|
|
+
|
|
|
+
|
|
|
+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: CERN-OHL-P (permissive); and
|
|
|
+two reciprocal licences: CERN-OHL-W (weakly reciprocal) and this
|
|
|
+licence, CERN-OHL-S (strongly reciprocal).
|
|
|
+
|
|
|
+The CERN-OHL-S 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.
|
|
|

|
|
+1 Definitions
|
|

|
|
+
|
|
|
+ a) any earlier version of the CERN Open Hardware licence, or
|
|
|
+
|
|
|
+ b) any version of the CERN-OHL-S, or
|
|
|
+
|
|
|
+ c) any licence which permits You to treat the Source to which
|
|
|
+ it applies as licensed under CERN-OHL-S provided that on
|
|
|
+ Conveyance of any such Source, or any associated Product You
|
|
|
+ treat the Source in question as being licensed under
|
|
|
+ CERN-OHL-S.
|
|
|
+
|
|
|
+ 1.3 'Source' means information such as design materials or digital
|
|
|
+ code which can be applied to Make or test a Product or to
|
|
|
+ prepare a Product for use, Conveyance or sale, regardless of its
|
|
|
+ medium or how it is expressed. It may include Notices.
|
|
|
+
|
|
|
+ 1.4 'Covered Source' means Source that is explicitly made available
|
|
|
+ under this Licence.
|
|
|
+
|
|
|
+ 1.5 'Product' means any device, component, work or physical object,
|
|
|
+ whether in finished or intermediate form, arising from the use,
|
|
|
+ application or processing of Covered Source.
|
|
|
+
|
|
|
+ 1.6 'Make' means to create or configure something, whether by

|
|
+ Licence; or
|
|
|
+
|
|
|
+ b) is available, at the time a Product or the Source containing
|
|
|
+ it is first Conveyed, to You and any other prospective
|
|
|
+ licensees
|
|
|
+
|
|
|
+ i) as a physical part with sufficient rights and
|
|
|
+ information (including any configuration and
|
|
|
+ programming files and information about its

|
|
|
+
|
|
|
+
|
|
|
+2 Applicability
|
|
|
+
|
|
|
+ 2.1 This Licence governs the use, copying, modification, Conveying
|
|
|
+ of Covered Source and Products, and the Making of Products. By
|
|
|
+ exercising any right granted under this Licence, You irrevocably
|
|
|
+ accept these terms and conditions.
|
|
|
+
|
|
|
+ 2.2 This Licence is granted by the Licensor directly to You, and
|
|
|
+ shall apply worldwide and without limitation in time.
|
|
|
+
|
|
|
+ 2.3 You shall not attempt to restrict by contract or otherwise the
|
|
|
+ rights granted under this Licence to other Licensees.
|
|
|
+
|
|
|
+ 2.4 This Licence is not intended to restrict fair use, fair dealing,
|
|
|
+ or any other similar right.
|
|
|
+
|
|
|
+
|
|
|
+3 Copying, modifying and Conveying Covered Source
|
|
|
+
|
|
|
+ 3.1 You may copy and Convey verbatim copies of Covered Source, in
|
|
|
+ any medium, provided You retain all Notices.
|
|
|
+
|
|
|
+ 3.2 You may modify Covered Source, other than Notices, provided that
|
|
|
+ You irrevocably undertake to make that modified Covered Source
|
|
|
+ available from a Source Location should You Convey a Product in
|
|
|
+ circumstances where the recipient does not otherwise receive a
|
|
|
+ copy of the modified Covered Source. In each case subsection 3.3
|
|
|
+ shall apply.
|
|
|
+
|
|
|
+ You may only delete Notices if they are no longer applicable to
|
|
|
+ the corresponding Covered Source as modified by You and You may
|
|
|
+ add additional Notices applicable to Your modifications.
|
|
|
+ Including Covered Source in a larger work is modifying the
|
|
|
+ Covered Source, and the larger work becomes modified Covered
|
|
|
+ Source.
|
|
|
+
|
|
|
+ 3.3 You may Convey modified Covered Source (with the effect that You
|
|
|
+ shall also become a Licensor) provided that You:
|
|
|
+
|
|
|
+ a) retain Notices as required in subsection 3.2;
|
|
|
+
|
|
|
+ b) add a Notice to the modified Covered Source stating that You
|
|
|
+ have modified it, with the date and brief description of how
|
|
|
+ You have modified it;
|
|
|
+
|
|
|
+ c) add a Source Location Notice for the modified Covered Source
|
|
|
+ if You Convey in circumstances where the recipient does not
|
|
|
+ otherwise receive a copy of the modified Covered Source; and
|
|
|
+
|
|
|
+ d) license the modified Covered Source under the terms and
|
|
|
+ conditions of this Licence (or, as set out in subsection
|
|
|
+ 8.3, a later version, if permitted by the licence of the
|
|
|
+ original Covered Source). Such modified Covered Source must
|
|
|
+ be licensed as a whole, but excluding Available Components
|
|
|
+ contained in it, which remain licensed under their own
|
|
|
+ applicable licences.
|
|
|
+
|
|
|
+
|
|
|
+4 Making and Conveying Products
|
|
|
+
|
|
|
+You may Make Products, and/or Convey them, provided that You either
|
|
|
+provide each recipient with a copy of the Complete Source or ensure
|
|
|
+that each recipient is notified of the Source Location of the Complete
|
|
|
+Source. That Complete Source is Covered Source, and You must
|
|
|
+accordingly satisfy Your obligations set out in subsection 3.3. If
|
|
|
+specified in a Notice, the Product must visibly and securely display
|
|
|
+the Source Location on it or its packaging or documentation in the
|
|
|
+manner specified in that Notice.
|
|
|
+
|
|
|
+
|
|
|
+5 Research and Development
|
|
|
+
|
|
|
+You may Convey Covered Source, modified Covered Source or Products to
|
|
|
+a legal entity carrying out development, testing or quality assurance
|
|
|
+work on Your behalf provided that the work is performed on terms which
|
|
|
+prevent the entity from both using the Source or Products for its own
|
|
|
+internal purposes and Conveying the Source or Products or any
|
|
|
+modifications to them to any person other than You. Any modifications
|
|
|
+made by the entity shall be deemed to be made by You pursuant to
|
|
|
+subsection 3.2.
|
|
|
+
|
|
|
+
|
|
|
+6 DISCLAIMER AND LIABILITY
|
|
|
+
|
|
|
+ 6.1 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.
|
|
|
+
|
|
|
+ 6.2 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.

|
+7 Patents
|
|
|
+
|
|
|
+ 7.1 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 subsections 7.2 and 8.4) 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.
|
|
|
+
|
|
|
+ 7.2 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.
|
|
|
+
|
|
|
+
|
|
|
+8 General
|
|
|
+
|
|
|
+ 8.1 If any provisions of this Licence are or subsequently become
|
|
|
+ invalid or unenforceable for any reason, the remaining
|
|
|
+ provisions shall remain effective.
|
|
|
+
|
|
|
+ 8.2 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.
|
|
|
+
|
|
|
+ 8.3 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.
|
|
|
+
|
|
|
+ 8.4 This Licence shall terminate with immediate effect if You fail
|
|
|
+ to comply with any of its terms and conditions.
|
|
|
+
|
|
|
+ 8.5 However, if You cease all breaches of this Licence, then Your
|
|
|
+ Licence from any Licensor is reinstated unless such Licensor has
|
|
|
+ terminated this Licence by giving You, while You remain in
|
|
|
+ breach, a notice specifying the breach and requiring You to cure
|
|
|
+ it within 30 days, and You have failed to come into compliance
|
|
|
+ in all material respects by the end of the 30 day period. Should
|
|
|
+ You repeat the breach after receipt of a cure notice and
|
|
|
+ subsequent reinstatement, this Licence will terminate
|
|
|
+ immediately and permanently. Section 6 shall continue to apply
|
|
|
+ after any termination.
|
|
|
+
|
|
|
+ 8.6 This Licence shall not be enforceable except by a Licensor
|
|
|
+ acting as such, and third party beneficiary rights are
|
|
|
+ specifically excluded.
