Wasn't that a requirement for being an AES submission?
As you may have guessed, I'm not a fan of permitting software to be
patented. Particularly things like RSA for which obvious prior art
existed, and the plethora of microprocessor patents which cover things
like doing branch prediction and switching instruction sets in absurdly
obvious and simple ways. Then you have the resulting silly lawsuits over
the silly patents and other innovation-suppressing and time-wasting
The corporate "Push to Patent" is remarkably similar to the academic "Push
to Publish." 90% of the output of either is not worth reading.
