| 1 | +CERN Open Hardware Licence Version 2 - Permissive |
| 2 | + |
| 3 | + |
| 4 | +Preamble |
| 5 | + |
| 6 | +CERN has developed this licence to promote collaboration among |
| 7 | +hardware designers and to provide a legal tool which supports the |
| 8 | +freedom to use, study, modify, share and distribute hardware designs |
| 9 | +and products based on those designs. Version 2 of the CERN Open |
| 10 | +Hardware Licence comes in three variants: this licence, CERN-OHL-P |
| 11 | +(permissive); and two reciprocal licences: CERN-OHL-W (weakly |
| 12 | +reciprocal) and CERN-OHL-S (strongly reciprocal). |
| 13 | + |
| 14 | +The CERN-OHL-P is copyright CERN 2020. Anyone is welcome to use it, in |
| 15 | +unmodified form only. |
| 16 | + |
| 17 | +Use of this Licence does not imply any endorsement by CERN of any |
| 18 | +Licensor or their designs nor does it imply any involvement by CERN in |
| 19 | +their development. |
| 20 | + |
| 21 | + |
| 22 | +1 Definitions |

| 113 | +5 DISCLAIMER AND LIABILITY |
| 114 | + |
| 115 | + 5.1 DISCLAIMER OF WARRANTY -- The Covered Source and any Products |

| 122 | + representation that any Source or Product does not or will not |
| 123 | + infringe any patent, copyright, trade secret or other |
| 124 | + proprietary right. The entire risk as to the use, quality, and |
| 125 | + performance of any Source or Product shall be with You and not |
| 126 | + the Licensor. This disclaimer of warranty is an essential part |
| 127 | + of this Licence and a condition for the grant of any rights |
| 128 | + granted under this Licence. |
| 129 | + |
| 130 | + 5.2 EXCLUSION AND LIMITATION OF LIABILITY -- The Licensor shall, to |
| 131 | + the maximum extent permitted by law, have no liability for |

| 135 | + use, data or profits, or business interruption, however caused |
| 136 | + and on any theory of contract, warranty, tort (including |
| 137 | + negligence), product liability or otherwise, arising in any way |
| 138 | + in relation to the Covered Source, modified Covered Source |
| 139 | + and/or the Making or Conveyance of a Product, even if advised of |
| 140 | + the possibility of such damages, and You shall hold the |
| 141 | + Licensor(s) free and harmless from any liability, costs, |
| 142 | + damages, fees and expenses, including claims by third parties, |
| 143 | + in relation to such use. |
| 144 | + |
| 145 | + |
| 146 | +6 Patents |
| 147 | + |
| 148 | + 6.1 Subject to the terms and conditions of this Licence, each |
| 149 | + Licensor hereby grants to You a perpetual, worldwide, |
| 150 | + non-exclusive, no-charge, royalty-free, irrevocable (except as |
| 151 | + stated in this section 6, or where terminated by the Licensor |
| 152 | + for cause) patent licence to Make, have Made, use, offer to |
| 153 | + sell, sell, import, and otherwise transfer the Covered Source |
| 154 | + and Products, where such licence applies only to those patent |
| 155 | + claims licensable by such Licensor that are necessarily |
| 156 | + infringed by exercising rights under the Covered Source as |
| 157 | + Conveyed by that Licensor. |
| 158 | + |
| 159 | + 6.2 If You institute patent litigation against any entity (including |
| 160 | + a cross-claim or counterclaim in a lawsuit) alleging that the |
| 161 | + Covered Source or a Product constitutes direct or contributory |
| 162 | + patent infringement, or You seek any declaration that a patent |
| 163 | + licensed to You under this Licence is invalid or unenforceable |
| 164 | + then any rights granted to You under this Licence shall |
| 165 | + terminate as of the date such process is initiated. |
| 166 | + |
| 167 | + |
| 168 | +7 General |
| 169 | + |
| 170 | + 7.1 If any provisions of this Licence are or subsequently become |
| 171 | + invalid or unenforceable for any reason, the remaining |
| 172 | + provisions shall remain effective. |
| 173 | + |
| 174 | + 7.2 You shall not use any of the name (including acronyms and |
| 175 | + abbreviations), image, or logo by which the Licensor or CERN is |
| 176 | + known, except where needed to comply with section 3, or where |
| 177 | + the use is otherwise allowed by law. Any such permitted use |
| 178 | + shall be factual and shall not be made so as to suggest any kind |
| 179 | + of endorsement or implication of involvement by the Licensor or |
| 180 | + its personnel. |
| 181 | + |
| 182 | + 7.3 CERN may publish updated versions and variants of this Licence |
| 183 | + which it considers to be in the spirit of this version, but may |
| 184 | + differ in detail to address new problems or concerns. New |
| 185 | + versions will be published with a unique version number and a |
| 186 | + variant identifier specifying the variant. If the Licensor has |
| 187 | + specified that a given variant applies to the Covered Source |
| 188 | + without specifying a version, You may treat that Covered Source |
| 189 | + as being released under any version of the CERN-OHL with that |
| 190 | + variant. If no variant is specified, the Covered Source shall be |
| 191 | + treated as being released under CERN-OHL-S. The Licensor may |
| 192 | + also specify that the Covered Source is subject to a specific |
| 193 | + version of the CERN-OHL or any later version in which case You |
| 194 | + may apply this or any later version of CERN-OHL with the same |
| 195 | + variant identifier published by CERN. |
| 196 | + |
| 197 | + 7.4 This Licence shall not be enforceable except by a Licensor |
| 198 | + acting as such, and third party beneficiary rights are |
| 199 | + specifically excluded. |
