Before everyone gets up in arms - I'm pretty sure that the patent
mentioned is not for the concept of continuations, but for a particular
implementation technique: using a metacircular bytecode interpreter to
allow certain portions of a program to capture first class continuations
even though the underlying VM (in this case, Java's) doesn't support them.
I have no idea whether or not this patent is valid, but it's not as
clearly bogus as one on continuations would be.
