It is offered as a basis for discussion and is not binding on the contributing individual(s) or organization(s). The material in this document is subject to change in form and content after further study. The contributor(s) reserve(s) the right to add, amend or withdraw material contained herein. Release: The contributor grants a free, irrevocable license to the IEEE to incorporate material contained in this contribution, and any modifications thereof, in the creation of an IEEE Standards publication; to copyright in the IEEE’s name any IEEE Standards publication even though it may include portions of this contribution; and at the IEEE’s sole discretion to permit others to reproduce in whole or in part the resulting IEEE Standards publication. The contributor also acknowledges and accepts that this contribution may be made public by IEEE 802.11. Patent Policy and Procedures: The contributor is familiar with the IEEE 802 Patent Policy and Procedures <http:// ieee802.org/guides/bylaws/sb-bylaws.pdf>, including the statement "IEEE standards may include the known use of patent(s), including patent applications, provided the IEEE receives assurance from the patent holder or applicant with respect to patents essential for compliance with both mandatory and optional portions of the standard." Early disclosure to the Working Group of patent information that might be relevant to the standard is essential to reduce the possibility for delays in the development process and increase the likelihood that the draft publication will be approved for publication. Please notify the Chair stuart@ok-brit.com as early as possible, in written or electronic form, if patented technology (or technology under patent application) might be incorporated into a draft standard being developed within the IEEE 802.11 Working Group. If you have questions, contact the IEEE Patent Committee Administrator at <patcom@ieee.org>. C. Wright, Azimuth Systems, Inc. C. Wright, Azimuth Systems, Inc.

IEEE-SA Standards Board Bylaws on Patents in Standards Doc.: IEEE 802.11-07/0063r2 January 2007 January 2007 IEEE-SA Standards Board Bylaws on Patents in Standards 6. Patents IEEE standards may include the known use of patent(s), including patent applications, provided the IEEE receives assurance from the patent holder or applicant with respect to patents essential for compliance with both mandatory and optional portions of the standard. This assurance shall be provided without coercion and prior to approval of the standard (or reaffirmation when a patent becomes known after initial approval of the standard). This assurance shall be a letter that is in the form of either a) A general disclaimer to the effect that the patentee will not enforce any of its present or future patent(s) whose use would be required to implement the proposed IEEE standard against any person or entity using the patent(s) to comply with the standard or b) A statement that a license will be made available without compensation or under reasonable rates, with reasonable terms and conditions that are demonstrably free of any unfair discrimination This assurance shall apply, at a minimum, from the date of the standard's approval to the date of the standard's withdrawal and is irrevocable during that period.

Straw Poll for All Remaining Deferred Comments January 2007 Straw Poll for All Remaining Deferred Comments The Task Group examined each of the deferred comments remaining in 11-06/0872r23 The following question was asked for each of the deferred comments: Is the draft considered to be technically complete without resolution of this comment? A new column in 11-06/0872r23 was added for recording each straw poll result After taking the straw polls, we again went over the list to look at the results On comments for which the results showed > 75% agreement, we asked again, Would members of the group object to a block motion to decline this comment? These CIDs are collected in a motion on the next slide A single objection was enough to keep the comment as “deferred” “Decline” here means we don’t need to resolve the comment before going to LB It does not mean the comment is not a legitimate comment! Members are free to resubmit the comment during a LB review C. Wright, Azimuth Systems, Inc.
