The TAPR Open Hardware License
|
|
Version 1.0 (May 25, 2007)
|
|
Copyright 2007 TAPR - http://www.tapr.org/OHL
|
|
|
|
PREAMBLE
|
|
|
|
Open Hardware is a thing - a physical artifact, either electrical or
|
|
mechanical - whose design information is available to, and usable by,
|
|
the public in a way that allows anyone to make, modify, distribute, and
|
|
use that thing. In this preface, design information is called
|
|
"documentation" and things created from it are called "products."
|
|
|
|
The TAPR Open Hardware License ("OHL") agreement provides a legal
|
|
framework for Open Hardware projects. It may be used for any kind of
|
|
product, be it a hammer or a computer motherboard, and is TAPR's
|
|
contribution to the community; anyone may use the OHL for their Open
|
|
Hardware project.
|
|
|
|
Like the GNU General Public License, the OHL is designed to guarantee
|
|
your freedom to share and to create. It forbids anyone who receives
|
|
rights under the OHL to deny any other licensee those same rights to
|
|
copy, modify, and distribute documentation, and to make, use and
|
|
distribute products based on that documentation.
|
|
|
|
Unlike the GPL, the OHL is not primarily a copyright license. While
|
|
copyright protects documentation from unauthorized copying, modification,
|
|
and distribution, it has little to do with your right to make, distribute,
|
|
or use a product based on that documentation. For better or worse, patents
|
|
play a significant role in those activities. Although it does not prohibit
|
|
anyone from patenting inventions embodied in an Open Hardware design, and
|
|
of course cannot prevent a third party from enforcing their patent rights,
|
|
those who benefit from an OHL design may not bring lawsuits claiming that
|
|
design infringes their patents or other intellectual property.
|
|
|
|
The OHL addresses unique issues involved in the creation of tangible,
|
|
physical things, but does not cover software, firmware, or code loaded
|
|
into programmable devices. A copyright-oriented license such as the GPL
|
|
better suits these creations.
|
|
|
|
How can you use the OHL, or a design based upon it? While the terms and
|
|
conditions below take precedence over this preamble, here is a summary:
|
|
|
|
* You may modify the documentation and make products based upon it.
|
|
|
|
* You may use products for any legal purpose without limitation.
|
|
|
|
* You may distribute unmodified documentation, but you must include the
|
|
complete package as you received it.
|
|
|
|
* You may distribute products you make to third parties, if you either
|
|
include the documentation on which the product is based, or make it
|
|
available without charge for at least three years to anyone who requests
|
|
it.
|
|
|
|
* You may distribute modified documentation or products based on it, if
|
|
you:
|
|
* License your modifications under the OHL.
|
|
* Include those modifications, following the requirements stated
|
|
below.
|
|
* Attempt to send the modified documentation by email to any of the
|
|
developers who have provided their email address. This is a good
|
|
faith obligation - if the email fails, you need do nothing more
|
|
and may go on with your distribution.
|
|
|
|
* If you create a design that you want to license under the OHL, you
|
|
should:
|
|
* Include this document in a file named LICENSE (with the appropriate
|
|
extension) that is included in the documentation package.
|
|
* If the file format allows, include a notice like "Licensed under
|
|
the TAPR Open Hardware License (www.tapr.org/OHL)" in each
|
|
documentation file. While not required, you should also include
|
|
this notice on printed circuit board artwork and the product
|
|
itself; if space is limited the notice can be shortened or
|
|
abbreviated.
|
|
* Include a copyright notice in each file and on printed circuit
|
|
board artwork.
|
|
* If you wish to be notified of modifications that others may make,
|
|
include your email address in a file named "CONTRIB.TXT" or
|
|
something similar.
|
|
|
|
* Any time the OHL requires you to make documentation available to
|
|
others, you must include all the materials you received from the
|
|
upstream licensors. In addition, if you have modified the
|
|
documentation:
|
|
* You must identify the modifications in a text file (preferably
|
|
named "CHANGES.TXT") that you include with the documentation.
|
|
That file must also include a statement like "These modifications
|
|
are licensed under the TAPR Open Hardware License."
|
|
* You must include any new files you created, including any
|
|
manufacturing files (such as Gerber files) you create in the
|
|
course of making products.
|
|
* You must include both "before" and "after" versions of all files
|
|
you modified.
|
|
* You may include files in proprietary formats, but you must also
|
|
include open format versions (such as Gerber, ASCII, Postscript,
|
|
or PDF) if your tools can create them.
|

TERMS AND CONDITIONS
|
|
|
|
1. Introduction
|
|
1.1 This Agreement governs how you may use, copy, modify, and
|
|
distribute Documentation, and how you may make, have made, and
|
|
distribute Products based on that Documentation. As used in this
|
|
Agreement, to "distribute" Documentation means to directly or indirectly
|
|
make copies available to a third party, and to "distribute" Products
|
|
means to directly or indirectly give, loan, sell or otherwise transfer
|
|
them to a third party.
|
|
|
|
1.2 "Documentation" includes:
|
|
(a) schematic diagrams;
|
|
(b) circuit or circuit board layouts, including Gerber and other
|
|
data files used for manufacture;
|
|
(c) mechanical drawings, including CAD, CAM, and other data files
|
|
used for manufacture;
|
|
(d) flow charts and descriptive text; and
|
|
(e) other explanatory material.
|
|
Documentation may be in any tangible or intangible form of expression,
|
|
including but not limited to computer files in open or proprietary
|
|
formats and representations on paper, film, or other media.
|
|
|
|
1.3 "Products" include:
|
|
(a) circuit boards, mechanical assemblies, and other physical parts
|
|
and components;
|
|
(b) assembled or partially assembled units (including components
|
|
and subassemblies); and
|
|
(c) parts and components combined into kits intended for assembly
|
|
by others;
|
|
which are based in whole or in part on the Documentation.
|
|
|
|
1.4 This Agreement applies to any Documentation which contains a
|
|
notice stating it is subject to the TAPR Open Hardware License, and to
|
|
all Products based in whole or in part on that Documentation. If
|
|
Documentation is distributed in an archive (such as a "zip" file) which
|
|
includes this document, all files in that archive are subject to this
|
|
Agreement unless they are specifically excluded. Each person who
|
|
contributes content to the Documentation is referred to in this
|
|
Agreement as a "Licensor."
|
|
|
|
1.5 By (a) using, copying, modifying, or distributing the
|
|
Documentation, or (b) making or having Products made or distributing
|
|
them, you accept this Agreement, agree to comply with its terms, and
|
|
become a "Licensee." Any activity inconsistent with this Agreement will
|
|
automatically terminate your rights under it (including the immunities
|
|
from suit granted in Section 2), but the rights of others who have
|
|
received Documentation, or have obtained Products, directly or
|
|
indirectly from you will not be affected so long as they fully comply
|
|
with it themselves.
|
|
|
|
1.6 This Agreement does not apply to software, firmware, or code
|
|
loaded into programmable devices which may be used in conjunction with
|
|
Documentation or Products. Such software is subject to the license
|
|
terms established by its copyright holder(s).
|
|
|
|
2. Patents
|
|
2.1 Each Licensor grants you, every other Licensee, and every
|
|
possessor or user of Products a perpetual, worldwide, and royalty-free
|
|
immunity from suit under any patent, patent application, or other
|
|
intellectual property right which he or she controls, to the extent
|
|
necessary to make, have made, possess, use, and distribute Products.
|
|
This immunity does not extend to infringement arising from modifications
|
|
subsequently made by others.
|
|
|
|
2.2 If you make or have Products made, or distribute Documentation
|
|
that you have modified, you grant every Licensor, every other Licensee,
|
|
and every possessor or user of Products a perpetual, worldwide, and
|
|
royalty-free immunity from suit under any patent, patent application, or
|
|
other intellectual property right which you control, to the extent
|
|
necessary to make, have made, possess, use, and distribute Products.
|
|
This immunity does not extend to infringement arising from modifications
|
|
subsequently made by others.
|
|
|
|
2.3 To avoid doubt, providing Documentation to a third party for the
|
|
sole purpose of having that party make Products on your behalf is not
|
|
considered "distribution,"\" and a third party's act of making Products
|
|
solely on your behalf does not cause that party to grant the immunity
|
|
described in the preceding paragraph.
|
|
|
|
2.4 These grants of immunity are a material part of this Agreement,
|
|
and form a portion of the consideration given by each party to the
|
|
other. If any court judgment or legal agreement prevents you from
|
|
granting the immunity required by this Section, your rights under this
|
|
Agreement will terminate and you may no longer use, copy, modify or
|
|
distribute the Documentation, or make, have made, or distribute
|
|
Products.
|
|
|
|
3. Modifications
|
|
You may modify the Documentation, and those modifications will become
|
|
part of the Documentation. They are subject to this Agreement, as are
|
|
Products based in whole or in part on them. If you distribute the
|
|
modified Documentation, or Products based in whole or in part upon it,
|
|
you must email the modified Documentation in a form compliant with
|
|
Section 4 to each Licensor who has provided an email address with the
|
|
Documentation. Attempting to send the email completes your obligations
|
|
under this Section and you need take no further action if any address
|
|
fails.
|
|
|
|
4. Distributing Documentation
|
|
4.1 You may distribute unmodified copies of the Documentation in its
|
|
entirety in any medium, provided that you retain all copyright and other
|
|
notices (including references to this Agreement) included by each
|
|
Licensor, and include an unaltered copy of this Agreement.
|
|
4.2 You may distribute modified copies of the Documentation if you
|
|
comply with all the requirements of the preceding paragraph and:
|
|
(a) include a prominent notice in an ASCII or other open format
|
|
file identifying those elements of the Documentation that you
|
|
changed, and stating that the modifications are licensed under
|
|
the terms of this Agreement;
|
|
(b) include all new documentation files that you create, as well as
|
|
both the original and modified versions of each file you change
|
|
(files may be in your development tool's native file format,
|
|
but if reasonably possible, you must also include open format,
|
|
such as Gerber, ASCII, Postscript, or PDF, versions);
|
|
(c) do not change the terms of this Agreement with respect to
|
|
subsequent licensees; and
|
|
(d) if you make or have Products made, include in the Documentation
|
|
all elements reasonably required to permit others to make
|
|
Products, including Gerber, CAD/CAM and other files used for
|
|
manufacture.
|
|
|
|
5. Making Products
|
|
5.1 You may use the Documentation to make or have Products made,
|
|
provided that each Product retains any notices included by the Licensor
|
|
(including, but not limited to, copyright notices on circuit boards).
|
|
5.2 You may distribute Products you make or have made, provided that
|
|
you include with each unit a copy of the Documentation in a form
|
|
consistent with Section 4. Alternatively, you may include either (i) an
|
|
offer valid for at least three years to provide that Documentation, at
|
|
no charge other than the reasonable cost of media and postage, to any
|
|
person who requests it; or (ii) a URL where that Documentation may be
|
|
downloaded, available for at least three years after you last distribute
|
|
the Product.
|
|
|
|
6. NEW LICENSE VERSIONS
|
|
TAPR may publish updated versions of the OHL which retain the same
|
|
general provisions as the present version, but differ in detail to
|
|
address new problems or concerns, and carry a distinguishing version
|
|
number. If the Documentation specifies a version number which applies
|
|
to it and "any later version", you may choose either that version or any
|
|
later version published by TAPR. If the Documentation does not specify
|
|
a version number, you may choose any version ever published by TAPR.
|
|
TAPR owns the copyright to the OHL, but grants permission to any person
|
|
to copy, distribute, and use it in unmodified form.
|
|
|
|
7. WARRANTY AND LIABILITY LIMITATIONS
|
|
7.1 THE DOCUMENTATION IS PROVIDED ON AN"AS-IS" BASIS WITHOUT
|
|
WARRANTY OF ANY KIND, TO THE EXTENT PERMITTED BY APPLICABLE LAW. ALL
|
|
WARRANTIES, EXPRESS OR IMPLIED, INCLUDING BUT NOT LIMITED TO ANY
|
|
WARRANTIES OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, AND
|
|
TITLE, ARE HEREBY EXPRESSLY DISCLAIMED.
|
|
7.2 IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW WILL ANY LICENSOR
|
|
BE LIABLE TO YOU OR ANY THIRD PARTY FOR ANY DIRECT, INDIRECT,
|
|
INCIDENTAL, CONSEQUENTIAL, PUNITIVE, OR EXEMPLARY DAMAGES ARISING OUT OF
|
|
THE USE OF, OR INABILITY TO USE, THE DOCUMENTATION OR PRODUCTS,
|
|
INCLUDING BUT NOT LIMITED TO CLAIMS OF INTELLECTUAL PROPERTY
|
|
INFRINGEMENT OR LOSS OF DATA, EVEN IF THAT PARTY HAS BEEN ADVISED OF THE
|
|
POSSIBILITY OF SUCH DAMAGES.
|
|
7.3 You agree that the foregoing limitations are reasonable due to
|
|
the non-financial nature of the transaction represented by this
|
|
Agreement, and acknowledge that were it not for these limitations, the
|
|
Licensor(s) would not be willing to make the Documentation available to
|
|
you.
|
|
7.4 You agree to defend, indemnify, and hold each Licensor harmless
|
|
from any claim brought by a third party alleging any defect in the
|
|
design, manufacture, or operation of any Product which you make, have
|
|
made, or distribute pursuant to this Agreement.
