Group Participation Home·Group participants (DBWG)·Member view of Groups
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 30 March 2007; see the Patent Policy FAQ for information about continued participation before re-joining the group.
Participants in this group have made certain licensing commitments by joining the group. 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.
The following is the list of specifications produced by the Voice Browser 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.
This section summarizes patent disclosures by participants in W3C's Voice Browser 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:
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.
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.
| Patent for Voice Browser Call Control: CCXML Version 1.0 | Excluded claims? | Notes on exclusions |
|---|---|---|
| Issued patent '6,701,366' (U.S. patent) held by Nortel Networks | all 30 claims | Nortel Inc. has excluded claims from U.S. patent no. 6,701,366 from the W3C RF licensing commitment. Nortel Inc. does not believe there are essential claims as defined in the W3C Patent Policy, but they do not guarantee the absence of essential claims. If there are essential claims, Nortel Inc indicated in their first disclosure statement that they are willing to license U.S.Patent no. 6,701,366 on RAND terms. The Voice PAG on CCXML recommends:
See the full PAG Report for more information. |
W3C Members and Invited Experts (including those not participating in this group) wishing to disclose a patent for any specification produced by the Voice Browser Working Group should use the Voice Browser 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.
Only Voice Browser 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 Voice Browser Working Group patent claim exclusion form, but only after first disclosing the patent.
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.
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:
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.
