agree with those who have observed the difficulties were IETF to
"tag all those that cite expired patents"

see for example  History of the Patent Policy of the American National 
Standards Institute at 
http://papers.ssrn.com/sol3/papers.cfm?abstract_id=2451165

clip

"1) An SDO needs to protect itself from involvement in litigation about the 
accuracy and completeness of statements and about infringements of patents 
due to use of the standard."

Subject: Expired patents

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
