JPEG 2000 Committee Drafts
Anyone implementing software according to the description available in draft versions of parts of JPEG 2000 risks not being compliant with the published standard, Part 1 of which is now published in its second edition as ISO/IEC 15444-1:2004.

The copyright of the text in the standard belongs to ISO/IEC, and it should not be reproduced in part or in any form without proper and prior authorization from the committee. This text is made available as is, without any warranties, and neither ISO/IEC, ITU-T, JPEG committee members nor their respective organisations can be held responsible for any damages, injuries or other problems that may be caused by using the algorithms described in this text. By downloading this text you accept these conditions.

Particular attention is drawn to the use within the standard of selected technology or algorithms which are claimed to be protected by national and/or international patents. In the case of technology submitted for consideration by JPEG for incorporation in Part 1 of the standard, the JPEG committee believes that the individual organisations concerned will make available licences to use this intellectual property, on a royalty- and fee-free basis, under specified conditions which may apply only to conforming implementations of the standard. These conditions are available on application to the organisations concerned, which are listed in an Annex to the document.

It is of course still possible that other organisations or individuals may claim intellectual property rights that affect implementation of the standard, and any implementors are urged to carry out their own searches and investigations in this area. The JPEG committee requests any organisations or individuals claiming (or being aware of claims) that any of the committee drafts available for download here infringes other intellectual property rights to provide information and/or evidence to substantiate their claim to the JPEG Convener in the first instance.
