There was some discussion of this here:


Sam Tobin-Hochstadt pointed out that the patent apparently relies on 
manual CPS, which makes sense given that it relates to a Common Lisp 

Still, I'd pay for tickets to see the court battle, with Yahoo lawyers 
arguing that CPS and call/cc based code is semantically equivalent, and 
demonstrating the transformation to the jury using a flip chart (don't 
tell them about PLT Redex!)  Hopefully Matthias will take the stand to 
argue that the required global transform clearly negates the patent.
