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 disclaimer of warranties + that are included in the Covered 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 licence 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. |
