I hope that someone can bridge the gap in my understanding between the IETF databases and those of the USPTO. Looking, for example, at http://datatracker.ietf.org/ipr/1339/ I see Patent, Serial, Publication, Registration, or Application/File number(s): US 12/708048 but when I go to the USPTO to search, they want a seven digit number for granted patents. Rather, this looks like an application number (not a patent number) but my searches for an application with that number fail as well, incorrect format. I can search full text and find US Patent 7593340 but that does not seem to share any data with the IETF tracker. (Incidentally, were I able to read Finnish, then there is an excellent database and I think I could retrieve what I wanted - but I cannot:-( Help appreciated.
