While that's true, if I remember right it's irrelevant in the context
of RSA.  [Wasn't the RSA patent filed around some time around 1976 then
issued in 1980 under the 17 year rule, then automatically extended to
20 years when that law was passed?]

Hmm...

Since Legi-Slate went out of business, I've not known of an easy way of
finding out the status of new laws.  [And, in this case, it looks like
my memory has gotten the better of me.]  I don't suppose you know of a
web site that tracks such things?

[I know, I can always visit the library, except right now I'm about 800
miles from the library I might normally use.]
