This page lists patent disclosures relative to the W3C XML Schema specification (part 0, part 1, part 2).
Any individual who has actual knowledge of a patent which the individual believes contains Essential Claim(s) with respect to this specification can and should disclose the information in accordance with section 6 of the W3C Patent Policy by filling out the appropriate disclosure form. See the W3C's IPP (Implementation of the Patent Policy) system for more information.
The following statements are the patent disclosures and license commitments associated with the specifications produced by the XML Schema Working Group and provided by members of the XML Schema Working Group as required 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 Working Group deliverables is vested in the W3C.
Per the W3C Current Patent Practice, disclosures made by W3C members are to be made public. In some cases, it is not clear whether the member intended the specifics of the disclosure to be member-confidential or public; in those cases, the disclosure is described without being reproduced.
Note: Members of the Working Group are expected to disclose any intellectual property they have in the area. This Working Group will work on a royalty-free basis, as defined in the W3C Current Patent Practice document. The Working Group is thus obliged to produce a specification which relies only on intellectual property available on a royalty-free basis.
