That is certainly a reasonable suggestion, but I suspect it can sometimes carry unfortunate complexities. For example imagine someone filing a continuing patent but not updating the IETF's records. There would be relevant IPR encumbrance but we wouldn't necessarily know it. No matter what we do or don't do, the record won't be perfect, but we probably should be cautious about having our records move from 'encumbered' to 'not encumbered' through any simple process such as a timeout. d/ -- Dave Crocker Brandenburg InternetWorking bbiw.net
