| 2 | |
| 3 | Adobe is the publisher of the Digital Negative (DNG) Specification |
| 4 | describing an image file format for storing camera raw information |
| 5 | used in a wide range of hardware and software. Adobe provides the DNG |
| 6 | Specification to the public for the purpose of encouraging |
| 7 | implementation of this file format in a compliant manner. This |
| 8 | document is a patent license granted by Adobe to individuals and |
| 9 | organizations that desire to develop, market, and/or distribute |
| 10 | hardware and software that reads and/or writes image files compliant |
| 11 | with the DNG Specification. |
| 12 | |
| 13 | Grant of rights |
| 14 | |
| 15 | Subject to the terms below and solely to permit the reading and |
| 16 | writing of image files that comply with the DNG Specification, Adobe |
| 17 | hereby grants all individuals and organizations the worldwide, |
| 18 | royalty-free, nontransferable, nonexclusive right under all Essential |
| 19 | Claims to make, have made, use, sell, import, and distribute Compliant |
| 20 | Implementations. |
| 21 | |
| 22 | “Compliant Implementation” means a portion of a software or hardware |
| 23 | product that reads or writes computer files compliant with the DNG |
| 24 | Specification. |
| 25 | |
| 26 | “DNG Specification” means any version of the Adobe DNG Specification |
| 27 | made publicly available by Adobe (for example, version 1.0.0.0 dated |
| 28 | September 2004). |
| 29 | |
| 30 | “Essential Claim” means a claim of a patent, whenever and wherever |
| 31 | issued, that Adobe has the right to license without payment of royalty |
| 32 | or other fee that is unavoidably infringed by implementation of the |
| 33 | DNG Specification. A claim is unavoidably infringed by the DNG |
| 34 | Specification only when it is not possible to avoid infringing when |
| 35 | conforming with such specification because there is no technically |
| 36 | possible noninfringing alternative for achieving such conformity. |
| 37 | Essential Claim does not include a claim that is infringed by |
| 38 | implementation of (a) enabling technology that may be necessary to |
| 39 | make or use any product or portion thereof that complies with the DNG |
| 40 | Specification but is not itself expressly set forth in the DNG |
| 41 | Specification (for example, compiler technology and basic operating |
| 42 | system technology), (b) technology developed elsewhere and merely |
| 43 | incorporated by reference in the DNG Specification, or (c) the |
| 44 | implementation of file formats other than DNG. |
| 45 | |
| 46 | Revocation |
| 47 | |
| 48 | Adobe may revoke the rights granted above to any individual or |
| 49 | organizational licensee in the event that such licensee or its |
| 50 | affiliates brings any patent action against Adobe or its affiliates |
| 51 | related to the reading or writing of files that comply with the DNG |
| 52 | Specification. |
| 53 | |
| 54 | Any Compliant Implementation distributed under this license must |
| 55 | include the following notice displayed in a prominent manner within |
| 56 | its source code and documentation: "This product includes DNG |
| 57 | technology under license by Adobe Systems Incorporated.” |
| 58 | |

| 61 | The rights granted herein are provided on an as-is basis without |
| 62 | warranty of any kind, including warranty of title or noninfringement. |
| 63 | Nothing in this license shall be construed as (a) requiring the |
| 64 | maintenance of any patent, (b) a warranty or representation as to the |
| 65 | validity or scope of any patent, (c) a warranty or representation that |
| 66 | any product or service will be free from infringement of any patent, |
| 67 | (d) an agreement to bring or prosecute actions against any infringers |
| 68 | of any patent, or (e) conferring any right or license under any patent |
