It is simply a convenient reference for understanding the the full Oculus SDK License Agreement. The Summary is written as a user-friendly interface to the full Oculus SDK License below. This Summary itself has no legal value, and its contents do not appear in the actual license. Full-length Legal Copy: 1. Subject to the terms and conditions of this License Agreement (the "License"), Oculus VR, Inc. ("Oculus VR") hereby grants to you a perpetual, worldwide, non-exclusive, no-charge, royalty-free, fully sublicenseable copyright license to use, reproduce, redistribute, modify, and improve the software contained in this Software Development Kit ("SDK"). This license includes the right to prepare derivative works ("Derivative Works"), whether in source, binary, or object form, based on the SDK including third party software unless otherwise noted. Derivative Works are defined as source, binary or object code derived exclusively from the SDK; provided, however, that Derivative Works do not include engines, utilities, applications, content or games which may be developed using the SDK. By way of example a videogame that is developed using the SDK would not be a Derivative Work and a utility or tool set in a pre-existing game engine that is adapted to work with the SDK would not be a Derivative Work. By way of example, but not limitation, a Derivative Work is or would be: either (i) an adaptation of a utility or piece of code from the SDK to improve efficiency; or (ii) an addition of code or improvement to the SDK that adds functionality. When you use the SDK (including Derivative Works) with your engines, utilities, applications, content or games you retain all rights thereto, and you have no obligations to share or license these items to Oculus or any third parties. 2. You, the recipient and user of the SDK, hereby agree and accept that that Oculus VR shall own all right, title and interest to the intellectual property rights, including, but limited to copyright, trademark and patent rights, to any Derivative Works that you or your licensees may create, and you hereby assign any and all such rights to such Derivative Works to Oculus VR. We hereby grant to you the right to use these Derivative Works solely in conjunction with the SDK on a fully paid up, no-charge, royalty-free, world-wide, in perpetuity, non-exclusive basis. Furthermore, for the sake of clarification, Oculus VR and its assignees and licensees shall be free to use such Derivative Works without any approval from you and without compensation or attribution to you. You also agree upon Oculus VR's request to provide the source and binary code of any Derivative Works to Oculus VR. FAILURE TO COMPLY WITH THIS REQUEST IS THE BASIS FOR AUTOMATIC TERMINATION OF THIS LICENSE BY OCULUS VR. 3. Subject to the terms and conditions of this License, your license to redistribute and sublicense the SDK and Derivate Works is also expressly made subject to the following conditions: 3.1. You may only sublicense and redistribute the source, binary, or object code of the SDK as a whole, and may not redistribute or sublicense any portion or element of the SDK separately by itself. You may only redistribute or sublicense Derivative Works solely with and as part of the SDK. The SDK may not be used, licensed, or sublicensed to interface with commercial headsets not authorized and approved by Oculus VR. 3.2. You must include with all such redistributed or sublicensed SDK code the following copyright notice: "Copyright © 2013 Oculus VR, Inc. All rights reserved," and include the list of conditions contained in this Section 3, including the full text of the disclaimer in Section 3.6 below; 3.3. Neither the name of Oculus VR, Inc. nor the names of Oculus VR, Inc.'s contributors, licensors, employees, or contractors, may be used to endorse or promote products derived from this SDK without specific prior written permission of Oculus VR, Inc.; 3.4. You must give any other recipients of the SDK or Derivative Works a copy of this License and you must cause any modified files to carry prominent notices stating that you changed the files; 3.5. If the SDK includes a "NOTICE" text file as part of its distribution, then any Derivative Works that you distribute with the SDK must include a readable copy of the attribution notices contained within such NOTICE file, excluding those notices that do not pertain to any part of the Derivative Works, in at least one of the following places: within a NOTICE text file distributed as part of the Derivative Works; within the source form or documentation, if provided along with the Derivative Works; or, within a display generated by the Derivative Works, if and wherever such third-party notices normally appear. The contents of the NOTICE file are for informational purposes only and do not modify the License. You may add your own attribution notices within Derivative Works that you distribute, alongside or as an addendum to the NOTICE text from the SDK, provided that such additional attribution notices cannot be construed as modifying the License. 3.6.

IN NO EVENT SHALL THE OCULUS VR AS THE COPYRIGHT OWNER OR ITS CONTRIBUTORS BE LIABLE FOR ANY DIRECT, INDIRECT, INCIDENTAL, SPECIAL, EXEMPLARY, OR CONSEQUENTIAL DAMAGES (INCLUDING, BUT NOT LIMITED TO, PROCUREMENT OF SUBSTITUTE GOODS OR SERVICES; LOSS OF USE, DATA, OR PROFITS; OR BUSINESS INTERRUPTION) HOWEVER CAUSED AND ON ANY THEORY OF LIABILITY, WHETHER IN CONTRACT, STRICT LIABILITY, OR TORT (INCLUDING NEGLIGENCE OR OTHERWISE) ARISING IN ANY WAY OUT OF THE USE OF THIS SDK OR THE DERIVATIVE WORKS, EVEN IF ADVISED OF THE POSSIBILITY OF SUCH DAMAGE. 4.
