ISO 15444 is covered by patents and the specification lists 17 patent holders, but the contributing companies and organizations agreed that licenses for its first part—the core coding system—can be obtained free of charge from all contributors. But this is not a formal guarantee.<ref>{{cite tech report |publisher=Library of Congress |location=Washington, D.C. |series=Sustainability of Digital Formats |type=Full draft |title=JPEG 2000 Part 1 (Core) jp2 File Format |date=27 April 2022 |url=https://www.loc.gov/preservation/digital/formats/fdd/fdd000143.shtml |access-date=23 February 2024}}</ref><ref>{{cite tech report |publisher=Library of Congress |location=Washington, D.C. |series=Sustainability of Digital Formats |type=Full draft |title=JPEG 2000 Part 1, Core Coding System |date=22 November 2022 |url=https://www.loc.gov/preservation/digital/formats/fdd/fdd000138.shtml |access-date=23 February 2024}}</ref> License and royalties may be required to use some extensions.<ref>{{cite tech report |publisher=Library of Congress |location=Washington, D.C. |series=Sustainability of Digital Formats |type=Full draft |title=JPEG 2000 Part 2 (Extensions) jpf (jpx) File Format |date=22 November 2022 |url=https://www.loc.gov/preservation/digital/formats/fdd/fdd000154.shtml |access-date=23 February 2024}}</ref><ref>{{cite tech report |publisher=Library of Congress |location=Washington, D.C. |series=Sustainability of Digital Formats |type=Full draft |title=JPEG 2000 Part 2, Coding Extensions |date=21 June 2005 |url=https://www.loc.gov/preservation/digital/formats/fdd/fdd000141.shtml |access-date=23 February 2024}}</ref>

The JPEG committee has stated:

{{quote|It has always been a strong goal of the JPEG committee that its standards should be implementable in their baseline form without payment of royalty and license fees... The up and coming JPEG&nbsp;2000 standard has been prepared along these lines, and agreement reached with over 20 large organizations holding many patents in this area to allow use of their intellectual property in connection with the standard without payment of license fees or royalties.<ref>{{Cite web|url=http://www.jpeg.org/newsrel1.html|archive-url=https://web.archive.org/web/20070714232941/http://www.jpeg.org/newsrel1.html|url-status=dead|title=JPEG 2000 Concerning recent patent claims|archive-date=July 14, 2007}}</ref>}}

However, the JPEG committee acknowledged in 2004 that undeclared [[submarine patent]]s may present a hazard:{{Importance inline|reason=Water is wet, too;  See also [[AV1#Patent_claims|AV1]] .  The difference here is that the vague 2004 statement on JPEG2000 was made on Feb 7th of that year;  patents last 20 years and they wouldn't have been referring to new patents at the time.  The threat on the base standard is dead and this section is rather pointless unless it's going to be boilerplate on every software page.  }}

{{quote|It is of course still possible that other organizations or individuals may claim intellectual property rights that affect implementation of the standard, and any implementers are urged to carry out their own searches and investigations in this area.<ref>{{Cite web|url=http://www.jpeg.org/jpeg2000/CDs15444.html|archive-url=https://web.archive.org/web/20060702065150/http://www.jpeg.org/jpeg2000/CDs15444.html|url-status=dead|title=JPEG 2000 Committee Drafts|archive-date=July 2, 2006}}</ref>}}

In ISO/IEC 15444-1:2016, the JPEG committee stated in "Annex L: Patent statement":

{{quote|The International Organization for Standardization (ISO) and the International Electrotechnical Commission (IEC) draw attention to the fact that it is claimed that compliance with this Recommendation {{!}} International Standard may involve the use of patents.

The complete list of intellectual property rights statements can be obtained from the ITU-T and ISO patent declaration databases (available at https://www.iso.org/iso-standards-and-patents.html)

ISO and IEC take no position concerning the evidence, validity and scope of these patent rights.

Attention is drawn to the possibility that some of the elements of this Recommendation {{!}} International Standard may be the subject of patent rights other than those identified in the above mentioned databases. ISO and IEC shall not be held responsible for identifying any or all such patent rights.}}
