Subject: RE: [pki-tc] Re: [egov] e-Gov: Distributing confidential informat ion

It does seem baffling that one can patent obvious uses of existing
technology - patents are supposed to encourage innovation, not stifle it...

From Tumbleweed's website, 


Some of the processes, arrangements, user interfaces, transaction sequences,
site and system architectures, data arrangements, and data processing
algorithms, described or embodied in this site and any affiliated or related
sites, are covered by one or more of the following U.S. Patents:   
      Patent No. 5,790,790 
      Patent No. 6,061,448 
      Patent No. 399,836 
      Patent No. 6,192,407 
      Patent No. 6,119,137 

If anyone figures out what these patents really cover (especially in terms
of how much of the obvious use of https for upload/download and mailing
https URLs), please let me know...

above opinions)

claim to having invented the idea of sending someone a HTTPS web link by 
     It would be even more fascinating if they think such a patent holds up 
outside of the United States.
     Did your correspondent provide either a patent registration number, or 
an identity, or a convincing line of argument, that can be shared with the 

Warm regards    Jamie
