privecsg ecsg 4 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 5 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
