HTML Working Group IPR disclosures

Note. The HTML Working Group was rechartered in August 2002. Please refer to the Patent Disclosures page for the rechartered HTML Working Group.

The following statements are the patent disclosures and license commitments associated with the deliverables of the HTML Working Group (members only) provided by Working Group members as suggested by the W3C Current Patent Practice.

W3C does not take a position regarding the validity or scope of any intellectual property right or other rights that might be claimed to pertain to the implementation or use of the technology, nor the extent to which any license under such rights might or might not be available. Copyright of WG deliverables is vested in the W3C.

Per the 19 July 2001 Process Document,

To disclose patent and IPR claims, individuals must send email to, which is an archived mailing list readable by Members and the Team.

Therefore, when a Member explicitly agrees to have its patent disclosure and IPR claims made public, they are included in this document.

Note: Members of the Working Group are expected to disclose any intellectual property they have in the area. This WG works on a royalty-free basis. The Working Group is thus obliged to produce a specification which relies only on intellectual property available on a royalty-free basis.

As of August 2002, the HTML Working Group participants and the W3C are not aware of any patents that are essential to implement the deliverables of the HTML Working Group, described in the HTML Working Group Charter.
