privecsg ecsg 2 Participants, Patents, and Duty to Inform All participants in this meeting have certain obligations under the IEEE-SA Patent Policy. Participants [Note: Quoted text excerpted from IEEE-SA Standards Board Bylaws subclause 6.2]: –“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 Early identification of holders of potential Essential Patent Claims is strongly encouraged No duty to perform a patent search

privecsg ecsg 3 Patent Related Links All participants should be familiar with their obligations under the IEEE-SA Policies & Procedures for standards development. Patent Policy is stated in these sources: –IEEE-SA Standards Boards Bylaws –IEEE-SA Standards Board Operations Manual Material about the patent policy is available at – If you have questions, contact the IEEE-SA Standards Board Patent Committee Administrator at or visit This slide set is available at

privecsg ecsg 4 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

privecsg ecsg 5 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 and “Promoting Competition and Innovation: What You Need to Know about the IEEE Standards Association's Antitrust and Competition Policy” for more details.

privecsg ecsg Trial at IETF meeting Trial IETF 91 Venue –Different SSID (e.g. ietf_PrivRandMAC?) –Separate VLAN, DHCP, Switching and AAA infrastructure –Will use only 2.4 GHz infrastructure (b/g/n) –Different credentials will be needed to join this network Wiki page and instructions for participants –Private requested to announce participation –IETF91 wiki page with instructions about how to use specific MAC address randomization tools and setup DHCP client name/ID per user– to debug and find out potential issues –If possible, user should keep track of MAC addresses being used – could help in case of collision or other issues

privecsg ecsg Implications of MAC address changes Statistics to be collected –Network # associations in this SSID DHCP logs (MAC, DHCP client ID, time/date) DHCP pool size in time Switch table size in time AAA logs –Client DHCP client name/ID MAC address usage log –Others?
