I was wondering whether there is a need for an occasional sweep over the IPR disclosures to tag all those that cite expired patents. We've been at this long enough that it is starting to be relevant. For example, I just noticed that IBM's NAT patent (US5371852) must have expired by now. It was discosed in https://datatracker.ietf.org/ipr/119/ and https://datatracker.ietf.org/ipr/208/ Regards Brian
