UniEngine Individual Contributor License Agreement

Thank you for your interest in contributing to the UniEngine project (“UniEngine”). In order to clarify the intellectual property license granted with Contributions from any person or entity, Maintainers („Maintainers“) of the UniEngine project, must have a Contributor License Agreement („Agreement“) that has been signed by each contributor, indicating agreement to the license terms below. This license is for your protection as a contributor as well as the protection of UniEngine and its users; it does not change your rights to use your own Contributions for any other purpose. Please read this agreement carefully before signing.

You accept and agree to the following terms and conditions for your past, present and future Contributions submitted to UniEngine. Except for the licenses granted in this Agreement, you retain all of your right, title and interest in and to your Contributions.

1. Definitions

„You“ (or „Your“) shall mean the copyright owner or legal entity authorized by the copyright owner that is making this Agreement with the Maintainers.

„Contribution“ or „Contributed materials“ shall mean any source code, object code, patch, tool, sample, graphic, specification, manual, documentation, or any other material submitted by You to UniEngine for inclusion in, or documentation of, any of the products owned or managed by the Maintainers (the „Work“). For the purposes of this definition, „submitted“ means any form of electronic, verbal, or written communication sent to the Maintainers or their representatives, including but not limited to communication on electronic mailing lists, source code control systems, and issue tracking systems that are managed by, or on behalf of, the Maintainers for the purpose of discussing and improving the Work, but excluding communication that is conspicuously marked or otherwise designated in writing by You as „Not a Contribution“.

2. Grant of Copyright License

Subject to the terms and conditions of this Agreement, You hereby grant to UniEngine and to recipients of software distributed by UniEngine a perpetual, worldwide, non-exclusive, no-charge, royalty-free, irrevocable copyright license to use, modify, reproduce, prepare derivative works of, publicly display, publicly perform, sublicense, transmit and distribute Your Contributions and such derivative works.

3. Grant of Patent License

Subject to the terms and conditions of this Agreement, You hereby grant to UniEngine and to recipients of software distributed by UniEngine a perpetual, worldwide, non-exclusive, no-charge, royalty-free, irrevocable (except as stated in this section) patent license to make, have made, use, offer to sell, sell, import, and otherwise transfer the Work, where such license applies only to those patent claims licensable by You that are necessarily infringed by Your Contribution(s) alone or by combination of Your Contribution(s) with the Work to which such Contribution(s) was submitted. If any entity institutes patent litigation against You or any other entity (including a cross-claim or counterclaim in a lawsuit) alleging that your Contribution, or the Work to which you have contributed, constitutes direct or contributory patent infringement, then any patent licenses granted to that entity under this Agreement for that Contribution or Work shall terminate as of the date such litigation is filed.

4. License grant entitlement

You represent that you are legally entitled to grant the above license. If your employer(s) has rights to intellectual property that you create that includes your Contributions, you represent that you have received permission to make Contributions on behalf of that employer, that your employer has waived such rights for your Contributions to UniEngine, or that your employer has executed a separate Corporate CLA with UniEngine.

5. Contributions ownership

You represent that each of Your Contributions is Your original creation (see section 6 for submissions on behalf of others). You represent that Your Contribution submissions include complete details of any third-party license or other restriction (including, but not limited to, related patents and trademarks) of which you are personally aware and which are associated with any part of Your Contributions.

6. Submissions on behalf of others

Should You wish to submit work that is not Your original creation, You may submit it to UniEngine separately from any Contribution, identifying the complete details of its source and of any license or other restriction (including, but not limited to, related patents, trademarks, and license agreements) of which you are personally aware, and conspicuously marking the work as „Submitted on behalf of a third-party: [named here]“.

7. Contributions warranties and support

You are not expected to provide support for Your Contributions, except to the extent You desire to provide support. You may provide support for free, for a fee, or not at all. Unless required by applicable law or agreed to in writing, You provide Your Contributions on an "AS IS" BASIS, WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or implied, including, without limitation, any warranties or conditions of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A PARTICULAR PURPOSE.

8. No Obligation

You acknowledge that the decision to include Your Contributions in UniEngine is entirely that of UniEngine's Maintainers. This Agreement does not guarantee that the Contributions will be included in any product.

9. End notes

You agree to notify UniEngine and its Maintainers of any facts or circumstances of which you become aware that would make these representations inaccurate in any respect.
