Assuming obviously that it would have been upheld if challenged. Even in 
1994 there was a lot of de-facto open-source code, including the source 
of OSes and development tools from IBM (and others), and quite a lot of 
that must have described novel stack manipulation strategies.

Elsewhere, I notice that IBM have moved Watson (which famously won a 
quiz contest a couple of years ago) into "the cloud" where it is being 
usefully employed by e.g. cancer researchers. It would be interesting to 
see what it made of the US patents archive.
