 CERN Open Hardware Licence Version 2 - Weakly 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: this licence, CERN- OHL-W (weakly reciprocal)
 and CERN-OHL-S (strongly reciprocal).

 The CERN-OHL-W 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

   1.1 'Licence' means this CERN-OHL-W.

   1.2 'Compatible Licence' means

        a) any earlier version of the CERN Open Hardware licence, or

        b) any version of the CERN-OHL-S or the CERN-OHL-W, or

        c) any licence which permits You to treat the Source to which
           it applies as licensed under CERN-OHL-S or CERN-OHL-W
           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 or CERN-OHL-W as appropriate.

   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
       manufacture, assembly, compiling, loading or applying Covered
       Source or another Product or otherwise.

   1.7 'Available Component' means any part, sub-assembly, library or
       code which:

       a) is licensed to You as Complete Source under a Compatible
          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) with sufficient rights and information (including any
               configuration and programming files and information
               about its characteristics and interfaces) to enable it
               either to be Made itself, or to be sourced and used to
               Make the Product; or
           ii) as part of the normal distribution of a tool used to
               design or Make the Product.

   1.8 'External Material' means anything (including Source) which:

       a) is only combined with Covered Source in such a way that it
          interfaces with the Covered Source using a documented
          interface which is described in the Covered Source; and

       b) is not a derivative of or contains Covered Source, or, if it
          is, it is solely to the extent necessary to facilitate such
          interfacing.

   1.9 'Complete Source' means the set of all Source necessary to Make
       a Product, in the preferred form for making modifications,
       including necessary installation and interfacing information
       both for the Product, and for any included Available Components.
       If the format is proprietary, it must also be made available in
       a format (if the proprietary tool can create it) which is
       viewable with a tool available to potential licensees and
       licensed under a licence approved by the Free Software
       Foundation or the Open Source Initiative. Complete Source need
       not include the Source of any Available Component, provided that
       You include in the Complete Source sufficient information to
       enable a recipient to Make or source and use the Available
       Component to Make the Product.

  1.10 'Source Location' means a location where a Licensor has placed
       Covered Source, and which that Licensor reasonably believes will
       remain easily accessible for at least three years for anyone to
       obtain a digital copy.

  1.11 'Notice' means copyright, acknowledgement and trademark notices,
       Source Location references, modification notices (subsection
       3.3(b)) and all notices that refer to this Licence and to the

       Source.

  1.12 'Licensee' or 'You' means any person exercising rights under
       this Licence.

  1.13 'Licensor' means a natural or legal person who creates or
       modifies Covered Source. A person may be a Licensee and a
       Licensor at the same time.

  1.14 'Convey' means to communicate to the public or distribute.


 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.

   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 or External Material to which it is
           interfaced, which remain licensed under their own applicable
           licences.


 4 Making and Conveying Products

   4.1 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 includes 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.

   4.2 Where You Convey a Product which incorporates External Material,
       the Complete Source for that Product which You are required to
       provide under subsection 4.1 need not include any Source for the
       External Material.

   4.3 You may license Products under terms of Your choice, provided
       that such terms do not restrict or attempt to restrict any
       recipients' rights under this Licence to the Covered Source.


 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.

       You may treat Covered Source licensed under CERN-OHL-W as
       licensed under CERN-OHL-S if and only if all Available
       Components referenced in the Covered Source comply with the
       corresponding definition of Available Component for CERN-OHL-S.

   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.
