Join or leave this group (see general instructions for joining this group).
Advisory Committee Representatives of participating Members may also
nominate or change representatives in the group.
The Call for Participation for
this group was announced on 7 March 2007; see the Patent Policy FAQ for information about continued participation before re-joining the group.
Licensing Commitments
Participants in this group have made certain licensing
commitments by joining the group.
In addition to these Participants,
1 non-participating W3C Member has committed to the Patent Policy Licensing terms.
See the details about licensing commitments
from current and past Participants and other parties.
W3C Members not participating in this group who wish to make the same
licensing commitments for specifications developed by this group may
do so through a form for licensing commitments from
non-participating Members.
Other parties who
wish to make the licensing commitments for this group
should consult the instructions for non-Members
to make licensing commitments for this group.
Specifications for this group
The following is the list of specifications produced by the HTML Working Group that have associated disclosures obligations, and possibly licensing obligations under the W3C Patent Policy.
See the detailed information on how to
disclose a patent, how to exclude a patent claim and how to add licensing terms below.
Note: If a specification does not appear in this
table, the group may have identified it as being "informative only."
To add or modify an item in this table,
please refer to the IPP
instructions.
Patent Disclosures and Claim Exclusions
This section summarizes patent disclosures by participants in W3C's HTML Working Group as required by section
6 of the 5
February 2004 W3C Patent Policy. Note: This disclosure
mechanism applies to all W3C Working Groups after 15 February 2004, per the
Patent Policy Transition
Procedure.
W3C takes no position
regarding either:
- 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, or
- the extent to which any license under such rights might or might not be
available from those not participating in this group.
W3C Members are obligated to disclose a patent when they receive a request for disclosure and have personal knowledge of the patent under the following conditions:
Where disclosure is required by a W3C Member, the AC Representative
makes the disclosure.
Anyone else may also make a disclosure.
Known Disclosures
Disclosures for
HTML 5
The entry in the first
column links to details about the disclosed patent,
including any excluded claims or additional licensing
information that has been provided.
How to Make a Patent Disclosure
W3C Members and Invited Experts
(including those not participating in this group)
wishing to disclose a patent for any
specification produced by the HTML Working Group should use the HTML Working Group patent
disclosure form.
Disclosures from the general public should be sent to the Staff Contacts of this group.
For specifications developed under the W3C Patent Policy, parties that commit to the W3C Royalty-Free Licensing Terms are not required to disclose patents. Any party (not just the Working Group Participants) may commit to the
W3C Royalty-Free Licensing Terms and may do so by following the
instructions in the next section.
Claim Exclusions
Only HTML Working Group participants may exclude patent claims concerning specifications developed under the W3C Patent Policy, per section
4 of the W3C Patent Policy. To make an exclusion, participants
should use the HTML Working Group patent claim
exclusion form, but only after first disclosing the patent.
Exclusion Opportunities
The Patent Policy FAQ provides detailed information
about exclusion opportunities, that is, when a
Working Group Participant can exclude a patent claim.
Each exclusion opportunity has a duration. See section
4.1 of the W3C Patent Policy and section 2 of
the Patent Policy Transition Procedure for information on how the
exclusion deadline is calculated.
At each exclusion opportunity, Participants may exclude patent
claims with respect to a body of text. The
Reference Draft is the reference body
of text for the current exclusion opportunity.
Note: At each new exclusion opportunity (e.g., in
the case of a second Last Call), exclusions are only with respect to
differences since the previous reference body of text. These
differences may be less than an entire document, and the summary below
does not (yet) address that granularity. Also, in some edge cases
(discussed in the FAQ),
Participants, depending on when they joined the Working Group, will
have different Reference Drafts; the summary below does not reflect this
case.

Additional Licensing Information
As described in
section
5 of the W3C Patent Policy:
All Working Group participants are encouraged to provide a contact
from which licensing information can be obtained and other relevant
licensing information. Any such information will be made publicly
available along with the patent disclosures for the Working Group in
question.
Patent holders may:
- Provide additional licensing information for documents produced by this Working Group
- Provide the same
additional licensing information for
all documents with associated licensing obligations
produced by this Working Group, or
- Provide additional licensing information
for any W3C document with associated licensing obligations
produced by any W3C Working Group under the W3C Patent Policy.
Please recall that, per section
5 of the W3C Patent Policy, a W3C Royalty-Free license:
may not impose any further conditions or restrictions on the use of
any technology, intellectual property rights, or other restrictions on
behavior of the licensee, but may include reasonable, customary terms
relating to operation or maintenance of the license relationship such
as the following: choice of law and dispute resolution.
Any additional licensing information that has been provided is
listed below. The section below will be empty when no
additional licensing information has been provided.
Note: All actions carried out through this system are reported by email to the relevant parties; copies are sent to w3c-archive@w3.org (Member-readable archive).
