W3C Community Final Specification Agreement 

To secure commitments from participants for the full text of a Community or
Business Group Report, the group may call for voluntary commitments to the following
terms; a "summary" is available. See also the related "W3C Community Contributor
License Agreement".

1. The Purpose of this Agreement.
This Agreement sets forth the terms under which I make certain copyright and
patent rights available to you for your implementation of the Specification.
Any other capitalized terms not specifically defined herein have the same meaning
as those terms have in the "W3C Patent Policy", and if not defined there, in
the "W3C Process Document".

2. Copyrights. 

2.1. Copyright Grant. I grant to you a perpetual (for the duration of the applicable
copyright), worldwide, non-exclusive, no-charge, royalty-free, copyright license,
without any obligation for accounting to me, to reproduce, prepare derivative
works of, publicly display, publicly perform, sublicense, distribute, and implement
the Specification to the full extent of my copyright interest in the Specification.

2.2. Attribution. As a condition of the copyright grant, you must include an
attribution to the Specification in any derivative work you make based on the
Specification. That attribution must include, at minimum, the Specification
name and version number.

3. Patents. 

3.1. Patent Licensing Commitment. I agree to license my Essential Claims under
the W3C Community RF Licensing Requirements. This requirement includes Essential
Claims that I own and any that I have the right to license without obligation
of payment or other consideration to an unrelated third party. W3C Community
RF Licensing Requirements obligations made concerning the Specification and
described in this policy are binding on me for the life of the patents in question
and encumber the patents containing Essential Claims, regardless of changes
in participation status or W3C Membership. I also agree to license my Essential
Claims under the W3C Community RF Licensing Requirements in derivative works
of the Specification so long as all normative portions of the Specification
are maintained and that this licensing commitment does not extend to any portion
of the derivative work that was not included in the Specification.

3.2. Optional, Additional Patent Grant. In addition to the provisions of Section
3.1, I may also, at my option, make certain intellectual property rights infringed
by implementations of the Specification, including Essential Claims, available
by providing those terms via the W3C Web site.

4. No Other Rights. Except as specifically set forth in this Agreement, no other
express or implied patent, trademark, copyright, or other property rights are
granted under this Agreement, including by implication, waiver, or estoppel.

5. Antitrust Compliance. I acknowledge that I may compete with other participants,
that I am under no obligation to implement the Specification, that each participant
is free to develop competing technologies and standards, and that each party
is free to license its patent rights to third parties, including for the purpose
of enabling competing technologies and standards.

6. Non-Circumvention. I agree that I will not intentionally take or willfully
assist any third party to take any action for the purpose of circumventing my
obligations under this Agreement.

7. Transition to W3C Recommendation Track. The Specification developed by the
Project may transition to the W3C Recommendation Track. The W3C Team is responsible
for notifying me that a Corresponding Working Group has been chartered. I have
no obligation to join the Corresponding Working Group. If the Specification
developed by the Project transitions to the W3C Recommendation Track, the following
terms apply:

7.1. If I join the Corresponding Working Group. If I join the Corresponding
Working Group, I will be subject to all W3C rules, obligations, licensing commitments,
and policies that govern that Corresponding Working Group.

7.2. If I Do Not Join the Corresponding Working Group. 

7.2.1. Licensing Obligations to Resulting Specification. If I do not join the
Corresponding Working Group, I agree to offer patent licenses according to the
W3C Royalty-Free licensing requirements described in Section 5 of the W3C Patent
Policy for the portions of the Specification included in the resulting Recommendation.
This licensing commitment does not extend to any portion of an implementation
of the Recommendation that was not included in the Specification. This licensing
commitment may not be revoked but may be modified through the exclusion process
defined in Section 4 of the W3C Patent Policy. I am not required to join the
Corresponding Working Group to exclude patents from the W3C Royalty-Free licensing
commitment, but must otherwise follow the normal exclusion procedures defined
by the W3C Patent Policy. The W3C Team will notify me of any Call for Exclusion
in the Corresponding Working Group as set forth in Section 4.5 of the W3C Patent
Policy.

7.2.2. No Disclosure Obligation. If I do not join the Corresponding Working
Group, I have no patent disclosure obligations outside of those set forth in
Section 6 of the W3C Patent Policy.

8. Conflict of Interest. I will disclose significant relationships when those
relationships might reasonably be perceived as creating a conflict of interest
with my role. I will notify W3C of any change in my affiliation using W3C-provided
mechanisms.

9. Representations, Warranties and Disclaimers. I represent and warrant that
I am legally entitled to grant the rights and promises set forth in this Agreement.
IN ALL OTHER RESPECTS THE SPECIFICATION IS PROVIDED “AS IS.” The entire
risk as to implementing or otherwise using the Specification is assumed by the
implementer and user. Except as stated herein, I expressly disclaim any warranties
(express, implied, or otherwise), including implied warranties of merchantability,
non-infringement, fitness for a particular purpose, or title, related to the
Specification. IN NO EVENT WILL ANY PARTY BE LIABLE TO ANY OTHER PARTY FOR LOST
PROFITS OR ANY FORM OF INDIRECT, SPECIAL, INCIDENTAL, OR CONSEQUENTIAL DAMAGES
OF ANY CHARACTER FROM ANY CAUSES OF ACTION OF ANY KIND WITH RESPECT TO THIS
AGREEMENT, WHETHER BASED ON BREACH OF CONTRACT, TORT (INCLUDING NEGLIGENCE),
OR OTHERWISE, AND WHETHER OR NOT THE OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY
OF SUCH DAMAGE. All of my obligations under Section 3 regarding the transfer,
successors in interest, or assignment of Granted Claims will be satisfied if
I notify the transferee or assignee of any patent that I know contains Granted
Claims of the obligations under Section 3. Nothing in this Agreement requires
me to undertake a patent search.

10. Definitions. 

10.1. Agreement. “Agreement” means this W3C Community Final Specification
Agreement.

10.2. Corresponding Working Group. “Corresponding Working Group” is a W3C
Working Group that is chartered to develop a Recommendation, as defined in the
W3C Process Document, that takes the Specification as an input.

10.3. Essential Claims. “Essential Claims” shall mean all claims in any
patent or patent application in any jurisdiction in the world that would necessarily
be infringed by implementation of the Specification. A claim is necessarily
infringed hereunder only when it is not possible to avoid infringing it because
there is no non-infringing alternative for implementing the normative portions
of the Specification. Existence of a non-infringing alternative shall be judged
based on the state of the art at the time of the publication of the Specification.
The following are expressly excluded from and shall not be deemed to constitute
Essential Claims:

10.3.1. any claims other than as set forth above even if contained in the same
patent as Essential Claims; and

10.3.2. claims which would be infringed only by: 
portions of an implementation that are not specified in the normative portions
of the Specification, or
enabling technologies that may be necessary to make or use any product or portion
thereof that complies with the Specification and are not themselves expressly
set forth in the Specification (e.g., semiconductor manufacturing technology,
compiler technology, object-oriented technology, basic operating system technology,
and the like); or
the implementation of technology developed elsewhere and merely incorporated
by reference in the body of the Specification.

10.3.3. design patents and design registrations.
For purposes of this definition, the normative portions of the Specification
shall be deemed to include only architectural and interoperability requirements.
Optional features in the RFC 2119 sense are considered normative unless they
are specifically identified as informative. Implementation examples or any other
material that merely illustrate the requirements of the Specification are informative,
rather than normative.

10.4. I, Me, or My. “I,” “me,” or “my” refers to the signatory.

10.5 Project. “Project” means the W3C Community Group or Business Group
for which I executed this Agreement.

10.6. Specification. “Specification” means the Specification identified
by the Project as the target of this agreement in a call for Final Specification
Commitments. W3C shall provide the authoritative mechanisms for the identification
of this Specification.

10.7. W3C Community RF Licensing Requirements. “W3C Community RF Licensing
Requirements” license shall mean a non-assignable, non-sublicensable license
to make, have made, use, sell, have sold, offer to sell, import, and distribute
and dispose of implementations of the Specification that:

10.7.1. shall be available to all, worldwide, whether or not they are W3C Members;

10.7.2. shall extend to all Essential Claims owned or controlled by me;

10.7.3. may be limited to implementations of the Specification, and to what
is required by the Specification;

10.7.4. may be conditioned on a grant of a reciprocal RF license (as defined
in this policy) to all Essential Claims owned or controlled by the licensee.
A reciprocal license may be required to be available to all, and a reciprocal
license may itself be conditioned on a further reciprocal license from all.

10.7.5. may not be conditioned on payment of royalties, fees or other consideration;

10.7.6. may be suspended with respect to any licensee when licensor issued by
licensee for infringement of claims essential to implement the Specification
or any W3C Recommendation;

10.7.7. 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;

10.7.8. shall not be considered accepted by an implementer who manifests an
intent not to accept the terms of the W3C Community RF Licensing Requirements
license as offered by the licensor.

10.7.9. The RF license conforming to the requirements in this policy shall be
made available by the licensor as long as the Specification is in effect. The
term of such license shall be for the life of the patents in question.
I am 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.

10.8. You or Your. “You,” “you,” or “your” means any person or entity
who exercises copyright or patent rights granted under this Agreement, and any
person that person or entity controls.
