- hardware and software that reads and/or writes image files compliant
- with the DNG Specification.
- Grant of rights
- Subject to the terms below and solely to permit the reading and
- writing of image files that comply with the DNG Specification, Adobe
- hereby grants all individuals and organizations the worldwide,

- “Essential Claim” means a claim of a patent, whenever and wherever
- issued, that Adobe has the right to license without payment of royalty
- or other fee that is unavoidably infringed by implementation of the
- DNG Specification. A claim is unavoidably infringed by the DNG
- Specification only when it is not possible to avoid infringing when
- conforming with such specification because there is no technically
- possible noninfringing alternative for achieving such conformity.
- Essential Claim does not include a claim that is infringed by
- implementation of (a) enabling technology that may be necessary to
- make or use any product or portion thereof that complies with the DNG

- include the following notice displayed in a prominent manner within
- its source code and documentation: "This product includes DNG
- technology under license by Adobe Systems Incorporated.”
- No warranty
- The rights granted herein are provided on an as-is basis without
- warranty of any kind, including warranty of title or noninfringement.
- Nothing in this license shall be construed as (a) requiring the
- maintenance of any patent, (b) a warranty or representation as to the
- validity or scope of any patent, (c) a warranty or representation that
- any product or service will be free from infringement of any patent,
