CERN Open Hardware Licence v1.2
CERN Open Hardware Licence Version 2 - Strongly Reciprocal
Preamble
Through this CERN Open Hardware Licence ("CERN OHL") version 1.2, CERN
wishes to provide a tool to foster collaboration and sharing among
hardware designers. The CERN OHL is copyright CERN. Anyone is welcome
to use the CERN OHL, in unmodified form only, for the distribution of
their own Open Hardware designs. Any other right is reserved. Release
of hardware designs under the CERN OHL does not constitute an
endorsement of the licensor or its designs nor does it imply any
involvement by CERN in the development of such designs.
CERN has developed this licence to promote collaboration among
hardware designers and to provide a legal tool which supports the
freedom to use, study, modify, share and distribute hardware designs
and products based on those designs. Version 2 of the CERN Open
Hardware Licence comes in three variants: CERN-OHL-P (permissive); and
two reciprocal licences: CERN-OHL-W (weakly reciprocal) and this
licence, CERN-OHL-S (strongly reciprocal).
1. Definitions
The CERN-OHL-S is copyright CERN 2020. Anyone is welcome to use it, in
unmodified form only.
In this Licence, the following terms have the following meanings:
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.
“Licence” means this CERN OHL.
“Documentation” means schematic diagrams, designs, circuit or circuit
board layouts, mechanical drawings, flow charts and descriptive text,
and other explanatory material that is explicitly stated as being made
available under the conditions of this Licence. The Documentation may
be in any medium, including but not limited to computer files and
representations on paper, film, or any other media.
1 Definitions
“Documentation Location” means a location where the Licensor has
placed Documentation, and which he believes will be publicly
accessible for at least three years from the first communication to
the public or distribution of Documentation.
1.1 'Licence' means this CERN-OHL-S.
“Product” means either an entire, or any part of a, device built using
the Documentation or the modified Documentation.
1.2 'Compatible Licence' means
“Licensee” means any natural or legal person exercising rights under
this Licence.
a) any earlier version of the CERN Open Hardware licence, or
“Licensor” means any natural or legal person that creates or modifies
Documentation and subsequently communicates to the public and/ or
distributes the resulting Documentation under the terms and conditions
of this Licence.
b) any version of the CERN-OHL-S, or
A Licensee may at the same time be a Licensor, and vice versa.
c) any licence which permits You to treat the Source to which
it applies as licensed under CERN-OHL-S 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.
Use of the masculine gender includes the feminine and neuter genders
and is employed solely to facilitate reading.
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.
2. Applicability
1.4 'Covered Source' means Source that is explicitly made available
under this Licence.
2.1. This Licence governs the use, copying, modification,
communication to the public and distribution of the Documentation, and
the manufacture and distribution of Products. By exercising any right
granted under this Licence, the Licensee irrevocably accepts these
terms and conditions.
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.
2.2. This Licence is granted by the Licensor directly to the Licensee,
and shall apply worldwide and without limitation in time. The Licensee
may assign his licence rights or grant sub-licences.
1.6 'Make' means to create or configure something, whether by
manufacture, assembly, compiling, loading or applying Covered
Source or another Product or otherwise.
2.3. This Licence does not extend to software, firmware, or code
loaded into programmable devices which may be used in conjunction with
the Documentation, the modified Documentation or with Products, unless
such software, firmware, or code is explicitly expressed to be subject
to this Licence. The use of such software, firmware, or code is
otherwise subject to the applicable licence terms and conditions.
1.7 'Available Component' means any part, sub-assembly, library or
code which:
3. Copying, modification, communication to the public and distribution
of the Documentation
a) is licensed to You as Complete Source under a Compatible
Licence; or
3.1. The Licensee shall keep intact all copyright and trademarks
notices, all notices referring to Documentation Location, and all
notices that refer to this Licence and to the disclaimer of warranties
that are included in the Documentation. He shall include a copy
thereof in every copy of the Documentation or, as the case may be,
modified Documentation, that he communicates to the public or
distributes.
b) is available, at the time a Product or the Source containing
it is first Conveyed, to You and any other prospective
licensees
3.2. The Licensee may copy, communicate to the public and distribute
verbatim copies of the Documentation, in any medium, subject to the
requirements specified in section 3.1.
i) as a physical part 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.
3.3. The Licensee may modify the Documentation or any portion thereof
provided that upon modification of the Documentation, the Licensee
shall make the modified Documentation available from a Documentation
Location such that it can be easily located by an original Licensor
once the Licensee communicates to the public or distributes the
modified Documentation under section 3.4, and, where required by
section 4.1, by a recipient of a Product. However, the Licensor shall
not assert his rights under the foregoing proviso unless or until a
Product is distributed.
1.8 '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.
3.4. The Licensee may communicate to the public and distribute the
modified Documentation (thereby in addition to being a Licensee also
becoming a Licensor), always provided that he shall:
1.9 '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.
a) comply with section 3.1;

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.
b) cause the modified Documentation to carry prominent notices stating
that the Licensee has modified the Documentation, with the date and
description of the modifications;
1.11 'Licensee' or 'You' means any person exercising rights under
this Licence.
c) cause the modified Documentation to carry a new Documentation
Location notice if the original Documentation provided for one;
1.12 '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.
d) make available the modified Documentation at the same level of
abstraction as that of the Documentation, in the preferred format for
making modifications to it (e.g. the native format of the CAD tool as
applicable), and in the event that format is proprietary, in a format
viewable with a tool licensed under an OSI-approved license if the
proprietary tool can create it; and
1.13 'Convey' means to communicate to the public or distribute.
e) license the modified Documentation under the terms and conditions
of this Licence or, where applicable, a later version of this Licence
as may be issued by CERN.
3.5. The Licence includes a non-exclusive licence to those patents or
registered designs that are held by, under the control of, or
sub-licensable by the Licensor, to the extent necessary to make use of
the rights granted under this Licence. The scope of this section 3.5
shall be strictly limited to the parts of the Documentation or
modified Documentation created by the Licensor.
2 Applicability
4. Manufacture and distribution of Products
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.
4.1. The Licensee may manufacture or distribute Products always
provided that, where such manufacture or distribution requires a
licence under this Licence the Licensee provides to each recipient of
such Products an easy means of accessing a copy of the Documentation
or modified Documentation, as applicable, as set out in section 3.
2.2 This Licence is granted by the Licensor directly to You, and
shall apply worldwide and without limitation in time.
4.2. The Licensee is invited to inform any Licensor who has indicated
his wish to receive this information about the type, quantity and
dates of production of Products the Licensee has (had) manufactured
2.3 You shall not attempt to restrict by contract or otherwise the
rights granted under this Licence to other Licensees.
5. Warranty and liability
2.4 This Licence is not intended to restrict fair use, fair dealing,
or any other similar right.
5.1. DISCLAIMER – The Documentation and any modified Documentation 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 the
Documentation, the modified Documentation or any Product. The Licensor
makes no representation that the Documentation, modified
Documentation, or any Product, does or will not infringe any patent,
copyright, trade secret or other proprietary right. The entire risk as
to the use, quality, and performance of a Product shall be with the
Licensee 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. The Licensee warrants that it does
not act in a consumer capacity.
5.2. LIMITATION OF LIABILITY – The Licensor shall 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
Documentation, modified Documentation and/or the use, manufacture or
distribution of a Product, even if advised of the possibility of such
damages, and the Licensee 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.
3 Copying, Modifying and Conveying Covered Source
6. General
3.1 You may copy and Convey verbatim copies of Covered Source, in
any medium, provided You retain all Notices.
6.1. Except for the rights explicitly granted hereunder, this Licence
does not imply or represent any transfer or assignment of intellectual
property rights to the Licensee.
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.
6.2. The Licensee shall not use or make reference to any of the names
(including acronyms and abbreviations), images, or logos under which
the Licensor is known, save in so far as required to comply with
section 3. Any such permitted use or reference shall be factual and
shall in no event suggest any kind of endorsement by the Licensor or
its personnel of the modified Documentation or any Product, or any
kind of implication by the Licensor or its personnel in the
preparation of the modified Documentation or Product.
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.
Including Covered Source in a larger work is modifying the
Covered Source, and the larger work becomes modified Covered
Source.
6.3. CERN may publish updated versions of this Licence which retain
the same general provisions as this version, but differ in detail so
far this is required and reasonable. New versions will be published
with a unique version number.
3.3 You may Convey modified Covered Source (with the effect that You
shall also become a Licensor) provided that You:
6.4. This Licence shall terminate with immediate effect, upon written
notice and without involvement of a court if the Licensee fails to
comply with any of its terms and conditions, or if the Licensee
initiates legal action against Licensor in relation to this
Licence. Section 5 shall continue to apply.
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, which remain licensed under their own
applicable licences.
4 Making and Conveying Products
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 is 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.
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.
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.
