"We learned that the sand is shifting with respect to the way the Patent Office is handling Bilski. What we learned is that things that we were doing in previous months are no longer acceptable. It seems that early last week a memo went out from the powers that be to the examiners handling Bilski-related applications, and in the memo it was explained that merely putting “computer implemented method” in the preamble of the claim is not something that will any longer work to overcome a patentable subject matter rejection under 35 U.S.C. 101. It seems that now you need to have “computer implemented method” in the preamble and there must also be positive recitation of “a computer” in the body of the claim."
