  3. IEEE-SA Standards Board Bylaws on Patents in Standards 6. Patents IEEE standards may include the known use of patent(s), including patent applications, provided the IEEE receives assurance from the patent holder or applicant with respect to patents essential for compliance with both mandatory and optional portions of the standard. This assurance shall be provided without coercion and prior to approval of the standard (or reaffirmation when a patent becomes known after initial approval of the standard). This assurance shall be a letter that is in the form of either a) A general disclaimer to the effect that the patentee will not enforce any of its present or future patent(s) whose use would be required to implement the proposed IEEE standard against any person or entity using the patent(s) to comply with the standard or b) A statement that a license will be made available without compensation or under reasonable rates, with reasonable terms and conditions that are demonstrably free of any unfair discrimination This assurance shall apply, at a minimum, from the date of the standard's approval to the date of the standard's withdrawal and is irrevocable during that period. Approved by IEEE-SA Standards Board – December 2002 Donald Eastlake 3rd, Motorola Laboratories

  4. Inappropriate Topics for IEEE SG Meetings • Don’t discuss licensing terms or conditions • Don’t discuss product pricing, territorial restrictions or market share • Don’t discuss ongoing litigation or threatened litigation • Don’t be silent if inappropriate topics are discussed… do formally object. If you have questions, contact the IEEE Patent Committee Administrator at patcom@ieee.org Approved by IEEE-SA Standards Board – December 2002 Donald Eastlake 3rd, Motorola Laboratories
