6Preamble
7
8CERN has developed this licence to promote collaboration among
9hardware designers and to provide a legal tool which supports the
10freedom to use, study, modify, share and distribute hardware designs
11and products based on those designs. 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.

1155 DISCLAIMER AND LIABILITY
116
117  5.1 DISCLAIMER OF WARRANTY -- The Covered Source and any Products
118      are provided 'as is' and any express or implied warranties,
119      including, but not limited to, implied warranties of
120      merchantability, of satisfactory quality, non-infringement of
121      third party rights, and fitness for a particular purpose or use
122      are disclaimed in respect of any Source or Product to the
123      maximum extent permitted by law. 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. This disclaimer of warranty is an essential part
129      of this Licence and a condition for the grant of any rights
130      granted under this Licence.
131
132  5.2 EXCLUSION AND LIMITATION OF LIABILITY -- The Licensor shall, to
133      the maximum extent permitted by law, have no liability for
134      direct, indirect, special, incidental, consequential, exemplary,
135      punitive or other damages of any character including, without
136      limitation, procurement of substitute goods or services, loss of
137      use, data or profits, or business interruption, however caused
138      and on any theory of contract, warranty, tort (including
139      negligence), product liability or otherwise, arising in any way
140      in relation to the Covered Source, modified Covered Source
141      and/or the Making or Conveyance of a Product, even if advised of
142      the possibility of such damages, and You shall hold the
143      Licensor(s) free and harmless from any liability, costs,
144      damages, fees and expenses, including claims by third parties,
145      in relation to such use.
146
147
1486 Patents
149
150  6.1 Subject to the terms and conditions of this Licence, each
151      Licensor hereby grants to You a perpetual, worldwide,
152      non-exclusive, no-charge, royalty-free, irrevocable (except as
153      stated in this section 6, or where terminated by the Licensor
154      for cause) patent license to Make, have Made, use, offer to
155      sell, sell, import, and otherwise transfer the Covered Source
156      and Products, where such licence applies only to those patent
157      claims licensable by such Licensor that are necessarily
158      infringed by exercising rights under the Covered Source as
159      Conveyed by that Licensor.
160
161  6.2 If You institute patent litigation against any entity (including
162      a cross-claim or counterclaim in a lawsuit) alleging that the
163      Covered Source or a Product constitutes direct or contributory
164      patent infringement, or You seek any declaration that a patent
165      licensed to You under this Licence is invalid or unenforceable
166      then any rights granted to You under this Licence shall
167      terminate as of the date such process is initiated.
168
169
1707 General
171
172  7.1 If any provisions of this Licence are or subsequently become
173      invalid or unenforceable for any reason, the remaining
174      provisions shall remain effective.
175
176  7.2 You shall not use any of the name (including acronyms and
177      abbreviations), image, or logo by which the Licensor or CERN is
178      known, except where needed to comply with section 3, or where
179      the use is otherwise allowed by law. 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.
