0 | CERN Open Hardware Licence Version 2 - Strongly Reciprocal | |
1 | ||
2 | ||
3 | Preamble | |
4 | ||
5 | CERN has developed this licence to promote collaboration among | |
6 | hardware designers and to provide a legal tool which supports the | |
7 | freedom to use, study, modify, share and distribute hardware designs | |
8 | and products based on those designs. Version 2 of the CERN Open | |
9 | Hardware Licence comes in three variants: CERN-OHL-P (permissive); and | |
10 | two reciprocal licences: CERN-OHL-W (weakly reciprocal) and this | |
11 | licence, CERN-OHL-S (strongly reciprocal). | |
12 | ||
13 | The CERN-OHL-S is copyright CERN 2020. Anyone is welcome to use it, in | |
14 | unmodified form only. | |
15 | ||
16 | Use of this Licence does not imply any endorsement by CERN of any | |
17 | Licensor or their designs nor does it imply any involvement by CERN in | |
18 | their development. | |
19 | ||
20 | ||
21 | 1 Definitions | |
22 | ||
23 | 1.1 'Licence' means this CERN-OHL-S. | |
24 | ||
25 | 1.2 'Compatible Licence' means | |
26 | ||
27 | a) any earlier version of the CERN Open Hardware licence, or | |
28 | ||
29 | b) any version of the CERN-OHL-S, or | |
30 | ||
31 | c) any licence which permits You to treat the Source to which | |
32 | it applies as licensed under CERN-OHL-S provided that on | |
33 | Conveyance of any such Source, or any associated Product You | |
34 | treat the Source in question as being licensed under | |
35 | CERN-OHL-S. | |
36 | ||
37 | 1.3 'Source' means information such as design materials or digital | |
38 | code which can be applied to Make or test a Product or to | |
39 | prepare a Product for use, Conveyance or sale, regardless of its | |
40 | medium or how it is expressed. It may include Notices. | |
41 | ||
42 | 1.4 'Covered Source' means Source that is explicitly made available | |
43 | under this Licence. | |
44 | ||
45 | 1.5 'Product' means any device, component, work or physical object, | |
46 | whether in finished or intermediate form, arising from the use, | |
47 | application or processing of Covered Source. | |
48 | ||
49 | 1.6 'Make' means to create or configure something, whether by | |
50 | manufacture, assembly, compiling, loading or applying Covered | |
51 | Source or another Product or otherwise. | |
52 | ||
53 | 1.7 'Available Component' means any part, sub-assembly, library or | |
54 | code which: | |
55 | ||
56 | a) is licensed to You as Complete Source under a Compatible | |
57 | Licence; or | |
58 | ||
59 | b) is available, at the time a Product or the Source containing | |
60 | it is first Conveyed, to You and any other prospective | |
61 | licensees | |
62 | ||
63 | i) as a physical part with sufficient rights and | |
64 | information (including any configuration and | |
65 | programming files and information about its | |
66 | characteristics and interfaces) to enable it either to | |
67 | be Made itself, or to be sourced and used to Make the | |
68 | Product; or | |
69 | ii) as part of the normal distribution of a tool used to | |
70 | design or Make the Product. | |
71 | ||
72 | 1.8 'Complete Source' means the set of all Source necessary to Make | |
73 | a Product, in the preferred form for making modifications, | |
74 | including necessary installation and interfacing information | |
75 | both for the Product, and for any included Available Components. | |
76 | If the format is proprietary, it must also be made available in | |
77 | a format (if the proprietary tool can create it) which is | |
78 | viewable with a tool available to potential licensees and | |
79 | licensed under a licence approved by the Free Software | |
80 | Foundation or the Open Source Initiative. Complete Source need | |
81 | not include the Source of any Available Component, provided that | |
82 | You include in the Complete Source sufficient information to | |
83 | enable a recipient to Make or source and use the Available | |
84 | Component to Make the Product. | |
85 | ||
86 | 1.9 'Source Location' means a location where a Licensor has placed | |
87 | Covered Source, and which that Licensor reasonably believes will | |
88 | remain easily accessible for at least three years for anyone to | |
89 | obtain a digital copy. | |
90 | ||
91 | 1.10 'Notice' means copyright, acknowledgement and trademark notices, | |

105 | ||
106 | ||
107 | 2 Applicability | |
108 | ||
109 | 2.1 This Licence governs the use, copying, modification, Conveying | |
110 | of Covered Source and Products, and the Making of Products. By | |
111 | exercising any right granted under this Licence, You irrevocably | |
112 | accept these terms and conditions. | |
113 | ||
114 | 2.2 This Licence is granted by the Licensor directly to You, and | |
115 | shall apply worldwide and without limitation in time. | |
116 | ||
117 | 2.3 You shall not attempt to restrict by contract or otherwise the | |
118 | rights granted under this Licence to other Licensees. | |
119 | ||
120 | 2.4 This Licence is not intended to restrict fair use, fair dealing, | |
121 | or any other similar right. | |
122 | ||
123 | ||
124 | 3 Copying, modifying and Conveying Covered Source | |
125 | ||
126 | 3.1 You may copy and Convey verbatim copies of Covered Source, in | |
127 | any medium, provided You retain all Notices. | |
128 | ||
129 | 3.2 You may modify Covered Source, other than Notices, provided that | |
130 | You irrevocably undertake to make that modified Covered Source | |
131 | available from a Source Location should You Convey a Product in | |
132 | circumstances where the recipient does not otherwise receive a | |
133 | copy of the modified Covered Source. In each case subsection 3.3 | |
134 | shall apply. | |
135 | ||
136 | You may only delete Notices if they are no longer applicable to | |
137 | the corresponding Covered Source as modified by You and You may | |
138 | add additional Notices applicable to Your modifications. | |
139 | Including Covered Source in a larger work is modifying the | |
140 | Covered Source, and the larger work becomes modified Covered | |
141 | Source. | |
142 | ||
143 | 3.3 You may Convey modified Covered Source (with the effect that You | |
144 | shall also become a Licensor) provided that You: | |
145 | ||
146 | a) retain Notices as required in subsection 3.2; | |
147 | ||
148 | b) add a Notice to the modified Covered Source stating that You | |
149 | have modified it, with the date and brief description of how | |
150 | You have modified it; | |
151 | ||
152 | c) add a Source Location Notice for the modified Covered Source | |
153 | if You Convey in circumstances where the recipient does not | |
154 | otherwise receive a copy of the modified Covered Source; and | |
155 | ||
156 | d) license the modified Covered Source under the terms and | |
157 | conditions of this Licence (or, as set out in subsection | |
158 | 8.3, a later version, if permitted by the licence of the | |
159 | original Covered Source). Such modified Covered Source must | |
160 | be licensed as a whole, but excluding Available Components | |
161 | contained in it, which remain licensed under their own | |
162 | applicable licences. | |
163 | ||
164 | ||
165 | 4 Making and Conveying Products | |
166 | ||
167 | You may Make Products, and/or Convey them, provided that You either | |
168 | provide each recipient with a copy of the Complete Source or ensure | |
169 | that each recipient is notified of the Source Location of the Complete | |
170 | Source. That Complete Source is Covered Source, and You must | |
171 | accordingly satisfy Your obligations set out in subsection 3.3. If | |
172 | specified in a Notice, the Product must visibly and securely display | |
173 | the Source Location on it or its packaging or documentation in the | |
174 | manner specified in that Notice. | |
175 | ||
176 | ||
177 | 5 Research and Development | |
178 | ||
179 | You may Convey Covered Source, modified Covered Source or Products to | |
180 | a legal entity carrying out development, testing or quality assurance | |
181 | work on Your behalf provided that the work is performed on terms which | |
182 | prevent the entity from both using the Source or Products for its own | |
183 | internal purposes and Conveying the Source or Products or any | |
184 | modifications to them to any person other than You. Any modifications | |
185 | made by the entity shall be deemed to be made by You pursuant to | |
186 | subsection 3.2. | |
187 | ||
188 | ||
189 | 6 DISCLAIMER AND LIABILITY | |
190 | ||
191 | 6.1 DISCLAIMER OF WARRANTY -- The Covered Source and any Products | |
192 | are provided 'as is' and any express or implied warranties, | |
193 | including, but not limited to, implied warranties of | |
194 | merchantability, of satisfactory quality, non-infringement of | |
195 | third party rights, and fitness for a particular purpose or use | |
196 | are disclaimed in respect of any Source or Product to the | |
197 | maximum extent permitted by law. The Licensor makes no | |
198 | representation that any Source or Product does not or will not | |
199 | infringe any patent, copyright, trade secret or other | |
200 | proprietary right. The entire risk as to the use, quality, and | |
201 | performance of any Source or Product shall be with You and not | |
202 | the Licensor. This disclaimer of warranty is an essential part | |
203 | of this Licence and a condition for the grant of any rights | |
204 | granted under this Licence. | |
205 | ||
206 | 6.2 EXCLUSION AND LIMITATION OF LIABILITY -- The Licensor shall, to | |
207 | the maximum extent permitted by law, have no liability for | |
208 | direct, indirect, special, incidental, consequential, exemplary, | |
209 | punitive or other damages of any character including, without | |
210 | limitation, procurement of substitute goods or services, loss of | |
211 | use, data or profits, or business interruption, however caused | |
212 | and on any theory of contract, warranty, tort (including | |
213 | negligence), product liability or otherwise, arising in any way | |
214 | in relation to the Covered Source, modified Covered Source | |
215 | and/or the Making or Conveyance of a Product, even if advised of | |
216 | the possibility of such damages, and You shall hold the | |
217 | Licensor(s) free and harmless from any liability, costs, | |
218 | damages, fees and expenses, including claims by third parties, | |
219 | in relation to such use. | |
220 | ||
221 | ||
222 | 7 Patents | |
223 | ||
224 | 7.1 Subject to the terms and conditions of this Licence, each | |
225 | Licensor hereby grants to You a perpetual, worldwide, | |
226 | non-exclusive, no-charge, royalty-free, irrevocable (except as | |
227 | stated in subsections 7.2 and 8.4) patent license to Make, have | |
228 | Made, use, offer to sell, sell, import, and otherwise transfer | |
229 | the Covered Source and Products, where such licence applies only | |
230 | to those patent claims licensable by such Licensor that are | |
231 | necessarily infringed by exercising rights under the Covered | |
232 | Source as Conveyed by that Licensor. | |
233 | ||
234 | 7.2 If You institute patent litigation against any entity (including | |
235 | a cross-claim or counterclaim in a lawsuit) alleging that the | |
236 | Covered Source or a Product constitutes direct or contributory | |
237 | patent infringement, or You seek any declaration that a patent | |
238 | licensed to You under this Licence is invalid or unenforceable | |
239 | then any rights granted to You under this Licence shall | |
240 | terminate as of the date such process is initiated. | |
241 | ||
242 | ||
243 | 8 General | |
244 | ||
245 | 8.1 If any provisions of this Licence are or subsequently become | |
246 | invalid or unenforceable for any reason, the remaining | |
247 | provisions shall remain effective. | |
248 | ||
249 | 8.2 You shall not use any of the name (including acronyms and | |
250 | abbreviations), image, or logo by which the Licensor or CERN is | |
251 | known, except where needed to comply with section 3, or where | |
252 | the use is otherwise allowed by law. Any such permitted use | |
253 | shall be factual and shall not be made so as to suggest any kind | |
254 | of endorsement or implication of involvement by the Licensor or | |
255 | its personnel. | |
256 | ||
257 | 8.3 CERN may publish updated versions and variants of this Licence | |
258 | which it considers to be in the spirit of this version, but may | |
259 | differ in detail to address new problems or concerns. New | |
260 | versions will be published with a unique version number and a | |
261 | variant identifier specifying the variant. If the Licensor has | |
262 | specified that a given variant applies to the Covered Source | |
263 | without specifying a version, You may treat that Covered Source | |
264 | as being released under any version of the CERN-OHL with that | |
265 | variant. If no variant is specified, the Covered Source shall be | |
266 | treated as being released under CERN-OHL-S. The Licensor may | |
267 | also specify that the Covered Source is subject to a specific | |
268 | version of the CERN-OHL or any later version in which case You | |
269 | may apply this or any later version of CERN-OHL with the same | |
270 | variant identifier published by CERN. | |
271 | ||
272 | 8.4 This Licence shall terminate with immediate effect if You fail | |
273 | to comply with any of its terms and conditions. | |
274 | ||
275 | 8.5 However, if You cease all breaches of this Licence, then Your | |
276 | Licence from any Licensor is reinstated unless such Licensor has | |
277 | terminated this Licence by giving You, while You remain in | |
278 | breach, a notice specifying the breach and requiring You to cure | |
279 | it within 30 days, and You have failed to come into compliance | |
280 | in all material respects by the end of the 30 day period. Should | |
281 | You repeat the breach after receipt of a cure notice and | |
282 | subsequent reinstatement, this Licence will terminate | |
283 | immediately and permanently. Section 6 shall continue to apply | |
284 | after any termination. | |
285 | ||
286 | 8.6 This Licence shall not be enforceable except by a Licensor | |
287 | acting as such, and third party beneficiary rights are | |
288 | specifically excluded. |
