PATENTS

+Alliance for Open Media Patent License 1.0
+
+1. License Terms.
+
+1.1. Patent License. Subject to the terms and conditions of this License, each
+     Licensor, on behalf of itself and successors in interest and assigns,
+     grants Licensee a non-sublicensable, perpetual, worldwide, non-exclusive,
+     no-charge, royalty-free, irrevocable (except as expressly stated in this
+     License) patent license to its Necessary Claims to make, use, sell, offer
+     for sale, import or distribute any Implementation.
+
+1.2. Conditions.
+
+1.2.1. Availability. As a condition to the grant of rights to Licensee to make,
+       sell, offer for sale, import or distribute an Implementation under
+       Section 1.1, Licensee must make its Necessary Claims available under
+       this License, and must reproduce this License with any Implementation
+       as follows:
+
+       a. For distribution in source code, by including this License in the
+          root directory of the source code with its Implementation.
+
+       b. For distribution in any other form (including binary, object form,
+          and/or hardware description code (e.g., HDL, RTL, Gate Level Netlist,
+          GDSII, etc.)), by including this License in the documentation, legal
+          notices, and/or other written materials provided with the
+          Implementation.
+
+1.2.2. Additional Conditions. This license is directly from Licensor to
+       Licensee.  Licensee acknowledges as a condition of benefiting from it
+       that no rights from Licensor are received from suppliers, distributors,
+       or otherwise in connection with this License.
+
+1.3. Defensive Termination. If any Licensee, its Affiliates, or its agents
+     initiates patent litigation or files, maintains, or voluntarily
+     participates in a lawsuit against another entity or any person asserting
+     that any Implementation infringes Necessary Claims, any patent licenses
+     granted under this License directly to the Licensee are immediately
+     terminated as of the date of the initiation of action unless 1) that suit
+     was in response to a corresponding suit regarding an Implementation first
+     brought against an initiating entity, or 2) that suit was brought to
+     enforce the terms of this License (including intervention in a third-party
+     action by a Licensee).
+
+1.4. Disclaimers. The Reference Implementation and Specification are provided
+     "AS IS" and without warranty. The entire risk as to implementing or
+     otherwise using the Reference Implementation or Specification is assumed
+     by the implementer and user. Licensor expressly disclaims any warranties
+     (express, implied, or otherwise), including implied warranties of
+     merchantability, non-infringement, fitness for a particular purpose, or
+     title, related to the material. IN NO EVENT WILL LICENSOR BE LIABLE TO
+     ANY OTHER PARTY FOR LOST PROFITS OR ANY FORM OF INDIRECT, SPECIAL,
+     INCIDENTAL, OR CONSEQUENTIAL DAMAGES OF ANY CHARACTER FROM ANY CAUSES OF
+     ACTION OF ANY KIND WITH RESPECT TO THIS LICENSE, WHETHER BASED ON BREACH
+     OF CONTRACT, TORT (INCLUDING NEGLIGENCE), OR OTHERWISE, AND WHETHER OR
+     NOT THE OTHER PARTRY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGE.

+     Deliverable.
+
+2.6. Implementation.  "Implementation" means any implementation, including the

+
+2.7. License. “License” means this license.
+
+2.8. Licensee. “Licensee” means any person or entity who exercises patent
+     rights granted under this License.
+
+2.9. Licensor.  "Licensor" means (i) any Licensee that makes, sells, offers

+     Media working group that developed the Specification.
+
+2.10. Necessary Claims.  "Necessary Claims" means all claims of patents or
+      patent applications, (a) that currently or at any time in the future,
+      are owned or controlled by the Licensor, and (b) (i) would be an

+      (https://www.w3.org/Consortium/Patent-Policy-20040205/#def-essential)
+      as if the Specification was a W3C Recommendation; or (ii) are infringed
+      by the Reference Implementation.
+
+2.11. Reference Implementation. “Reference Implementation” means an Encoder
+      and/or Decoder released by the Alliance for Open Media as a Final
+      Deliverable.
+
+2.12. Specification. “Specification” means the specification designated by
+      the Alliance for Open Media as a Final Deliverable for which this
+      License was issued.
