1.7 "Attribution Notice" means a clear, human-readable and machine-readable notice that: (a) identifies the Software by name; (b) identifies the Licensor; (c) states that the Software is licensed under HLIB v1; and (d) includes a link or reference to the full text of this License.
2.1 Use and Integration. Subject to Your compliance with this License, the Licensor hereby grants You a worldwide, royalty-free, non-exclusive, revocable (as provided in Section 8) license to:
(a) use, reproduce, and integrate the Software into Integrations;
(b) modify, adapt, and create derivative works of the Software;
(c) distribute the Software, modified or unmodified, in source or object form, as part of an Integration or standalone;
(d) sublicense the rights granted in this Section 2 to Downstream Users, provided such sublicensing is consistent with this License.
2.2 Commercial Use. Commercial use of the Software, including integration into commercial products and services, is permitted under this License, provided that all conditions in Section 3 are met.
2.3 API / SDK Usage. You may expose, wrap, or re-export the Software's APIs through Your own APIs or SDKs, provided that You do not misrepresent the origin of the Software and comply with Section 3.
3.1 Attribution. Any distribution of the Software, in source or object form, or any public deployment of an Integration that prominently exposes the Software's functionality, must include a reasonable Attribution Notice. The Attribution Notice may be placed in documentation, an "About" screen, a NOTICE file, or an equivalent location.
3.2 License and Copyright Notice. You must retain all copyright, patent, trademark, and attribution notices contained within the Software. You must include a copy of this License with any distribution of the Software.
3.3 State of Changes. If You modify the Software, You must cause the modified files to carry prominent notices stating that You changed the files and the date of any change. This requirement does not apply to Integrations that merely use the Software without modifying it.
3.4 No Misrepresentation of Origin. You may not represent the Software as Your own original work, nor may You remove or obscure the Licensor's name or the Software's name in a way that misleads Downstream Users.
3.5 Sublicensing. Any sublicense granted under Section 2.1(d) must be subject to terms no less protective of the Licensor than those in this License, and You must provide a copy of this License to each Downstream User.
You may add Your own terms and conditions to Integrations that use the Software, provided such terms do not:
(a) restrict any Downstream User's rights under this License with respect to the Software itself;
(b) create any obligation or liability for the Licensor;
(c) imply any endorsement by the Licensor of Your Integration.
5.1 Subject to the terms of this License, the Licensor grants You a non-exclusive, worldwide, royalty-free patent license under the Licensor's patent claims that are necessarily infringed by the Software as distributed by the Licensor, to make, use, sell, offer for sale, import, and otherwise transfer the Software, where such license applies only to those patent claims licensable by the Licensor that are necessarily infringed by the Software alone or by combination of the Software with the Integration to which the Software was linked.
5.2 Patent Retaliation. If You institute patent litigation against the Licensor or any other entity (including a cross-claim or counterclaim in a lawsuit) alleging that the Software or an Integration constitutes direct or contributory patent infringement, then any patent licenses granted to You under this License shall terminate as of the date such litigation is filed.
This License does not grant permission to use the trade names, trademarks, service marks, or product names of the Licensor, except as required for reasonable and customary use in describing the origin of the Software and reproducing the content of the NOTICE file.
THE SOFTWARE IS PROVIDED "AS IS", WITHOUT WARRANTY OF ANY KIND, EXPRESS OR IMPLIED, INCLUDING BUT NOT LIMITED TO THE WARRANTIES OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, TITLE, AND NON-INFRINGEMENT.

10.2 Severability. If any provision of this License is held to be invalid or unenforceable, that provision shall be enforced to the maximum extent permissible, and the remaining provisions shall remain in full force and effect.
