Version 2 of the CERN Open 12Hardware Licence comes in three variants: this licence, CERN-OHL-P 13(permissive); and two reciprocal licences: CERN- OHL-W (weakly 14reciprocal) and CERN-OHL-S (strongly reciprocal). 15 16The CERN-OHL-P is copyright CERN 2020. Anyone is welcome to use it, in 17unmodified form only. 18 19Use of this Licence does not imply any endorsement by CERN of any 20Licensor or their designs nor does it imply any involvement by CERN in 21their development. 22 23 241 Definitions 25 26 1.1 'Licence' means this CERN-OHL-P. 27 28 1.2 'Source' means information such as design materials or digital 29 code which can be applied to Make or test a Product or to 30 prepare a Product for use, Conveyance or sale, regardless of its 31 medium or how it is expressed. It may include Notices. 32 33 1.3 'Covered Source' means Source that is explicitly made available 34 under this Licence. 35 36 1.4 'Product' means any device, component, work or physical object, 37 whether in finished or intermediate form, arising from the use, 38 application or processing of Covered Source. 39 40 1.5 'Make' means to create or configure something, whether by 41 manufacture, assembly, compiling, loading or applying Covered 42 Source or another Product or otherwise. 43 44 1.6 'Notice' means copyright, acknowledgement and trademark notices, 45 references to the location of any Notices, modification notices 46 (subsection 3.3(b)) and all notices that refer to this Licence 47 and to the disclaimer of warranties that are included in the 48 Covered Source. 49 50 1.7 'Licensee' or 'You' means any person exercising rights under 51 this Licence. 52 53 1.8 'Licensor' means a person who creates Source or modifies Covered 54 Source and subsequently Conveys the resulting Covered Source 55 under the terms and conditions of this Licence.

The Licensor makes no 124 representation that any Source or Product does not or will not 125 infringe any patent, copyright, trade secret or other 126 proprietary right. The entire risk as to the use, quality, and 127 performance of any Source or Product shall be with You and not 128 the Licensor.

Any such permitted use 180 shall be factual and shall not be made so as to suggest any kind 181 of endorsement or implication of involvement by the Licensor or 182 its personnel. 183 184 7.3 CERN may publish updated versions and variants of this Licence 185 which it considers to be in the spirit of this version, but may 186 differ in detail to address new problems or concerns. New 187 versions will be published with a unique version number and a 188 variant identifier specifying the variant. If the Licensor has 189 specified that a given variant applies to the Covered Source 190 without specifying a version, You may treat that Covered Source 191 as being released under any version of the CERN-OHL with that 192 variant. If no variant is specified, the Covered Source shall be 193 treated as being released under CERN-OHL-S. The Licensor may 194 also specify that the Covered Source is subject to a specific 195 version of the CERN-OHL or any later version in which case You 196 may apply this or any later version of CERN-OHL with the same 197 variant identifier published by CERN. 198 199 7.4 This Licence shall not be enforceable except by a Licensor 200 acting as such, and third party beneficiary rights are 201 specifically excluded. 202
