Current status of RSA patent...

Can anyone provide additional information on the RSA patent status? 
If memory serves me, it is due to expire sometime in 1997. 

Also, what are the ramifications of deploying software based around it, 
such as PGP 2.62i (from UK)?

This does not make sense...  If you believe that RSA has a back door, then
PGP _must_ have a back door because PGP uses it!  It does not matter if
it was independently coded and reviewed.  There could still be a back door
if it was made that way intentionally.

I think you need to replaces your SIMMs, your memory is faulty.  RSA
lives until 2000 (or 2003, I forget); 1997 is Diffie-Helman.

What you think would happen based on the fact that the patent hasn't
expired.

PGP 2.6.2i is not US codebase, and RSA is not patented outside the US 
according to Bruce Schneiner. Therefore, if a product was deployed into 
the US using a non-US codebase, it is unclear to me what legal 
jurisdiction (if any) RSA may have in these circumstances.
