3. doc.: IEEE 802.11-09/0495r1 Submission May 2009 Bruce Kraemer, MarvellSlide 3 Prior Resolution UNRESOLVABLE 802.11 WG, TGn and the TGn CRC believe they have faithfully followed the procedures provided by PatCom concerning the soliciting of potentially essential patents and associated LOAs as specified in: http://standards.ieee.org/board/pat/pat-slideset.ppt TGn CRC has asked the WG11 chair to pass this comment on to PatCom for further review and advice. While awaiting further advice, TGn CRC and WG11 will continue to follow IEEE IP procedures. It has also been noted that the status of LOAs believed relevant to P802.11n will need to be reviewed prior to a request for Standards Board approval and publication as there are potentially two paragraphs that could be selected from the IEEE-SA Ops Manual (sub-clause "6.3.1 Public Notice") for inclusion in the P802.11n front matter (currently page iv of the draft). One paragraph applies when LOAs are not received, and one for when LOAs are received.

4. doc.: IEEE 802.11-09/0495r1 Submission May 2009 Bruce Kraemer, MarvellSlide 4 Posted PatCom Guidance What is an essential patent? Essential patents are those patents whose infringement is, or in the case of patent applications, potential future infringement the applicant asserts will be, unavoidable in a compliant implementation of either mandatory or optional portions of a standard. The oversight of the IEEE process is only concerned with essential patents. Call for essential patents by the Working Group Chair What exactly is a call for essential patents? It's a reminder, made by the chair of an IEEE standards-developing working group or the chair of an IEEE Standards Sponsor. The chair informs the members of the working group that if any individual believes that a patent or patent application might be essential to the implementation of the standard, that fact should be made known to the entire working group. This request shall be made at every standards-development meeting, usually as part of the chair's introductory remarks. Anyone can respond to this call, be they observers or members of the group. There is no obligation to search patent portfolios and no patent numbers are required to be identified as part of the call for patents--just information that something may be of issue. Once the chair is made aware of this, he or she can send out a patent letter of assurance request to the potential patent holder for official confirmation of information.request So what can you discuss about patents at a standards-development meeting? You can cover the content of the patent letter of assurance form, you can discuss the technical merits of using the technology under patent, and you can discuss the way patent information is made available from the IEEE. You must not discuss subjects like the pricing for use of a patent, how a patent should be licensed, validity or interpretation of a patent claim, or any terms or conditions of use. These are not appropriate topics for discussion in a standards developing committee. Further information can be found in "What You Need to Know About IEEE Standards and the Law."What You Need to Know About IEEE Standards and the Law Questions from industry or from individuals can be directed to the IEEE-SA Standards Board Patent Committee for further consideration.IEEE-SA Standards Board Patent Committee Source: http://standards.ieee.org/board/pat/guide.html
