Participants have a duty to inform the IEEE May 2015 doc.: IEEE 802.11-15/0496r1 May 2019 Participants have a duty to inform the IEEE Participants shall inform the IEEE (or cause the IEEE to be informed) of the identity of each holder of any potential Essential Patent Claims of which they are personally aware if the claims are owned or controlled by the participant or the entity the participant is from, employed by, or otherwise represents Participants should inform the IEEE (or cause the IEEE to be informed) of the identity of any other holders of potential Essential Patent Claims Early identification of holders of potential Essential Patent Claims is encouraged Edward Au (Huawei Technologies) Edward Au (Marvell Semiconductor)

May 2015 doc.: IEEE 802.11-15/0496r1 May 2019 Ways to inform IEEE Cause an LOA to be submitted to the IEEE-SA (patcom@ieee.org); or Provide the chair of this group with the identity of the holder(s) of any and all such claims as soon as possible; or Speak up now and respond to this Call for Potentially Essential Patents If anyone in this meeting is personally aware of the holder of any patent claims that are potentially essential to implementation of the proposed standard(s) under consideration by this group and that are not already the subject of an Accepted Letter of Assurance, please respond at this time by providing relevant information to the WG Chair Edward Au (Huawei Technologies) Edward Au (Marvell Semiconductor)

Guideline for IEEE WG meetings May 2019 Guideline for IEEE WG meetings All IEEE-SA standards meetings shall be conducted in compliance with all applicable laws, including antitrust and competition laws. Don’t discuss the interpretation, validity, or essentiality of patents/patent claims. Don’t discuss specific license rates, terms, or conditions. Relative costs of different technical approaches that include relative costs of patent licensing terms may be discussed in standards development meetings. Technical considerations remain the primary focus Don’t discuss or engage in the fixing of product prices, allocation of customers, or division of sales markets. Don’t discuss the status or substance of ongoing or threatened litigation. Don’t be silent if inappropriate topics are discussed … do formally object. --------------------------------------------------------------- For more details, see IEEE-SA Standards Board Operations Manual, clause 5.3.10 and Antitrust and Competition Policy: What You Need to Know at http://standards.ieee.org/develop/policies/antitrust.pdf Edward Au (Huawei Technologies)

Reminder on comment resolution May 2015 doc.: IEEE 802.11-15/0496r1 May 2019 Reminder on comment resolution A few reminders Make sure the proposed resolution is executable by the Editor, e.g., please avoid that there is not enough info to be able for the Editor to resolve the comment without creating text by himself. Make sure to call out not only the page and line number, but also the draft version and clause number in your comment resolution document, because the page and line numbers (also the figure and table numbers) change on subsequent revisions of the drafts Reference: https://mentor.ieee.org/802.11/dcn/18/11-18-1391-00-0000-september-2018-working-group-chair-supplementary-material.ppt https://mentor.ieee.org/802.11/dcn/13/11-13-0230-03-0000-comment-resolution-tutorial.ppt Edward Au (Huawei Technologies) Edward Au (Marvell Semiconductor)

making changes to the approved draft May 2015 doc.: IEEE 802.11-15/0496r1 May 2019 Reminder on making changes to the approved draft A few reminders The task group that “owns” the draft can make any changes it likes for any reason whatsoever during the ballot cycle, provided that the changes are approved by 75% motion in the TG. These changes are recirculated to voters, and identified in the draft redline. Voters can comment on these changes and may vote “no” if they don’t like them. In the interest of reaching closure, the TG is advised to limit these changes to the early stages of a ballot series.
