Hi all, In IEEE we are admonished to never discuss the essentiality or validity of patent claims. I cannot believe this is considered an appropriate discussion in IETF.

There is no apparent connection with oam-msg-map - in fact the claims stress that the triggers are failures of PSN elements (e.g. S-PEs) and are NOT from the ACs, making any connection untenable. A previous disclosure by the same company (863) refers to 20080285466 : Interworking between MPLS/IP and Ethernet OAM mechanisms which may impact mpls-eth-oam-iwk, but not oam-msg-map, unless one interprets the first claim and its dependents much more broadly than supported by the background and description. Can someone from the company claiming this IPR fix the information in these disclosures ? At very least that company is required to disclose IPR is holds with respect to the appropriate drafts (unless it is willing to risk forfeiting its rights with respect to these ...). However, with respect to oam-msg-map I would like to request that it consider removing inappropriate disclosures. Of course, if after consideration it believes that these disclosures ARE appropriate, I would love to hear the reasoning.
