• Review of operating rules for PHY ad hoc

• Submissions

Review of ad hoc operating rules

• The following summary is derived from 11-12/239r2• Pre-Motion: A pre-motion (doesn’t require voting rights) result of

>=75% is required within an Ad Hoc to approve the resolution of all or part of an issue and forward that resolved item to the Taskgroup where it becomes a motion that requires >=75% approval to modify the specification framework or the draft specification.– Note: the term Pre-Motion was introduced by 11ac ad hoc operating rules to create

a distinction between straw polls which intent is to result in a Motion at the Taskgroup, and strawpolls which intent is to only gauge the opinion of the members on a particular topic and are not intended to results in a motion at the Taskgroup.

• Stalemate: In the case a consensus can not be reached within an Ad Hoc group (a stalemate that prohibits further progress), the subject is moved to the Taskgroup if an Ad Hoc straw poll vote to move the subject to the Taskgroup achieves >50% approval.

Review of ad hoc operating rules

• Transfer to another ad hoc: A motion passing with >50% in the Taskgroup shall be sufficient to move an issue previously assigned to an Ad Hoc group to any Ad Hoc group. A straw poll vote of >50% is required in an Ad Hoc group to refuse an issue from the Taskgroup.

• Transfer to another ad hoc: An issue may be sent from one Ad Hoc to another if both the sending Ad Hoc and the receiving Ad Hoc approve straw polls for taking the respective actions with >50% approval. A notice should be sent to the reflector indicating the approval of a straw poll to move an issue.

• To be accepted into the Draft specification, proposals from Ad Hoc group require a motion that passes with >=75% Taskgroup approval

Slide 20

doc.: IEEE 802.11-12/0895r2

Submission

The IEEE-SA strongly recommends that at each WG meeting the chair or a designee:

– Show slides #1 through #4 of this presentation– Advise the WG attendees that:

• The IEEE’s patent policy is consistent with the ANSI patent policy and is described in Clause 6 of the IEEE-SA Standards Board Bylaws;

• Early identification of patent claims which may be essential for the use of standards under development is strongly encouraged;

• There may be Essential Patent Claims of which the IEEE is not aware. Additionally, neither the IEEE, the WG, nor the WG chair can ensure the accuracy or completeness of any assurance or whether any such assurance is, in fact, of a Patent Claim that is essential for the use of the standard under development.

– Instruct the WG Secretary to record in the minutes of the relevant WG meeting: • That the foregoing information was provided and that slides 1 through 4 (and this slide 0, if applicable) were shown; • That the chair or designee provided an opportunity for participants to identify patent claim(s)/patent application claim(s)

and/or the holder of patent claim(s)/patent application claim(s) of which the participant is personally aware and that may be essential for the use of that standard

• Any responses that were given, specifically the patent claim(s)/patent application claim(s) and/or the holder of the patent claim(s)/patent application claim(s) that were identified (if any) and by whom.

– The WG Chair shall ensure that a request is made to any identified holders of potential essential patent claim(s) to complete and submit a Letter of Assurance.

– It is recommended that the WG chair review the guidance in IEEE-SA Standards Board Operations Manual 6.3.5 and in FAQs 12 and 12a on inclusion of potential Essential Patent Claims by incorporation or by reference.

Note: WG includes Working Groups, Task Groups, and other standards-developing committees with a PAR approved by the IEEE-SA Standards Board.

Participants, Patents, and Duty to Inform

All participants in this meeting have certain obligations under the IEEE-SA Patent Policy. 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

“Personal awareness” means that the participant “is personally aware that the holder may have a potential Essential Patent Claim,” even if the participant is not personally aware of the specific patents or patent claims

“Should inform the IEEE (or cause the IEEE to be informed)” of the identity of “any other holders of such potential Essential Patent Claims” (that is, third parties that are not affiliated with the participant, with the participant’s employer, or with anyone else that the participant is from or otherwise represents)

The above does not apply if the patent claim is already the subject of an Accepted Letter of Assurance that applies to the proposed standard(s) under consideration by this group

Quoted text excerpted from IEEE-SA Standards Board Bylaws subclause 6.2 Early identification of holders of potential Essential Patent Claims is strongly encouraged No duty to perform a patent search

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: – Either speak up now 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– Cause an LOA to be submitted

Other Guidelines 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, including licensing costs of essential patent claims, of different technical

approaches may be discussed in standards development meetings. Technical considerations remain 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.

--------------------------------------------------------------- See IEEE-SA Standards Board Operations Manual, clause 5.3.10 and “Promoting Competition and Innovation:

What You Need to Know about the IEEE Standards Association's Antitrust and Competition Policy” for more details.

Member Affiliation

• It is defined in the IEEE-SA Standards Board Bylaws, 5.2.1.5 as: “An individual is deemed “affiliated” with any individual or entity that has been, or will be, financially or materially supporting that individual’s participation in a particular IEEE standards activity. This includes, but is not limited to, his or her employer and any individual or entity that has or will have, either directly or indirectly, requested, paid for, or otherwise sponsored his or her participation.

Slide 27

Declaration of Affiliation

• Revision: May 2007 Standards Board Bylaw 5.2.1.1– 5.2.1.1 Openness

• Openness is defined as the quality of being not restricted to a particular type or category of participants. All meetings involving standards development an all IEEE Sponsor ballots shall be open toa all interested parties. Each individual participant in IEEE Standards activities shall disclose his or her affiliations when requested. A person who knows or reasonably should know, that a participant’s disclosure is materially incomplete or incorrect should report that fact to the Secretary of the IEEE-SA Standards Board and the appropriate Sponsors.

Slide 28

Affiliation Policy• Requirement to declare affiliation at all standards

development meetings and recorded in the minutes– Affiliation not necessarily same as employer– Declaration requirement may be familiar to some 802 WGs, though

WG declaration process may evolve• 11. What if I refuse to disclose my affiliation?

– As outlined in IEEE-SA governance documents, you will lose certain rights. In a working group where voting rights are gained through attendance, no attendance credit will be granted if affiliation isn’t declared. Similarly, voting rights are to be removed if affiliation isn’t declared.

• Affiliation declaration will be added to Sponsor ballot• http://standards.ieee.org/faqs/affiliationFAQ.html
