doc. : IEEE 802. 11 -15/1232 r 3 November 2015 Instructions for the WG Chair 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 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 14 and 15 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.
