CERN Open Hardware Licence Version 2 - Permissive Preamble CERN has developed this licence to promote collaboration among hardware designers and to provide a legal tool for the dissemination of hardware designs. The CERN Open Hardware Licence Version 2 is available in two variants: Weakly Reciprocal (CERN-OHL-W) and Permissive (CERN-OHL-P). The CERN-OHL-P is for you if you want to maximise the ability of people to use your hardware design including for use in commercial applications with a minimum of obligations. It is a continuation of the CERN Open Hardware Licence version 1 (but with a new structure) and is focused more narrowly on the design itself and what you must do to give proper credit and to allow others to build and modify the design. Please see the CERN-OHL version 2 family page (www.ohwr.org/cernohl) for more information. Terms and conditions 1. Definitions In this Licence, the following terms have the following meanings: “Additive” means something you add to the Design that was not part of it when it was first published by the Licensor. “Design” means the design documentation for the hardware that is licensed under this Licence, in any format or medium. It may include both the Hardware Description and the Modifications. “Documentation” means all the materials that are provided by the Licensor or any Contributor to describe the Design, including schematics, netlists, PCB layout files, bills of materials, drawings, specifications, and the like, and also includes the Modifications. “Hardware” means any physical device that embodies the Design or any part thereof, in any form. “Hardware Description” means the files that specify the Hardware in a form that can be read by a computer and that, when used appropriately, can be used to fabricate Hardware, for example in whole or in part. “Licence” means this licence (the CERN-OHL-P). “Licensor” means the person or entity that first publishes the Design under the terms of this Licence. “Modification” means any change to the Design, including changes to the Hardware Description. “Product” means either an unchanged Design or a Design with Modifications, that is offered for sale, or otherwise made available for commercial use, whether as Hardware or in other forms. “Source” means the format of the Design that is preferred for making Modifications, including all the files that are provided for that purpose. “You” means any person or entity that exercises any right under this Licence. 2. What this Licence covers The Licensor grants you a worldwide, royalty-free, non-exclusive, perpetual licence to: a) use the Design and any associated Documentation, b) make Modifications, c) communicate the Design and any Documentation, including by making it available for copying and modification, d) manufacture and distribute Hardware that implements the Design or any part thereof, e) sell Products, and f) otherwise deal in the Design or any part thereof, all in each case subject to the conditions set out in this Licence. 3. Conditions 3.1. Availability of Source The Design and any Documentation that is made available under this Licence must be made available in Source format. If the Design is available in a format that is not Source, you must also make a version of the Design in Source format available, and you must inform others of how to obtain it. 3.2. Retention of copyright and other notices You must retain all copyright and other notices that appear in the Design or Documentation. 3.3. Notice of Modifications If you make Modifications, you must include a notice in any Distribution of the Design or Documentation, stating that Modifications have been made, by whom, and in what they consist. 3.4. Distribution of Modifications If you distribute any Design or Documentation, whether unchanged or with Modifications, you must distribute it under this Licence, and you must inform the recipient that the Design or Documentation is licensed under this Licence. 3.5. No implicit approval The Licensor shall not be taken to have approved any Modifications unless the Licessor expressly approves them in writing. 4. Disclaimer of warranty THE DESIGN AND ANY DOCUMENTATION IS PROVIDED "AS IS" AND THE LICENSOR MAKES NO WARRANTY, EXPRESS OR IMPLIED, INCLUDING BUT NOT LIMITED TO WARRANTIES OF MERCHANTABILITY, SATISFACTORY QUALITY, NON-INFRINGEMENT, TITLE, AND FITNESS FOR A PARTICULAR PURPOSE. THE DESIGN MAY CONTAIN DESIGN DEFECTS OR ERRORS THAT MAKE IT UNSUITABLE FOR USE IN CERTAIN APPLICATIONS. THE ENTIRE RISK AS TO ITS QUALITY AND PERFORMANCE REMAINS WITH YOU. 5. Limitation of liability TO THE EXTENT NOT PROHIBITED BY LAW, IN NO EVENT WILL THE LICENSOR BE LIABLE FOR ANY DAMAGES WHATSOEVER, INCLUDING WITHOUT LIMITATION LOST PROFITS, PROCUREMENT OF SUBSTITUTE GOODS OR SERVICES, OR ANY OTHER LOSSES ARISING OUT OF THE USE OF THE DESIGN OR ANY DOCUMENTATION, HOWEVER CAUSED, WHETHER UNDER THEORY OF CONTRACT, TORT (INCLUDING NEGLIGENCE), PRODUCTS LIABILITY, OR OTHERWISE, EVEN IF ADVISED OF THE POSSIBILITY OF SUCH DAMAGES. 6. Termination This Licence is perpetual except that if you fail to comply with its terms, your rights under this Licence will terminate immediately. If you bring or defend any litigation or other claim alleging that the Design or any part thereof infringes any intellectual property right, all your rights under this Licence granted by the Licensor will terminate forty-five days after you bring or defend such claim. 7. General This Licence shall be governed by the laws of the country of the Licensor, without reference to its conflict of laws provisions. If any part of this Licence is held to be invalid or unenforceable, the remaining parts shall remain in full force and effect. --------------------------------------------------------------------- CERN-OHL-P is a variant of the CERN-OHL family.
