I Don't Believe in Imaginary Property writes "The Supreme Court's review of In Re Bilski (discussed here numerous times) is heating up, having attracted no less than 44 friend-of-the-court briefs from almost everyone with a stake in the patent system. Patently-O provides a nice summary of who is arguing against Bilski. The two questions before the Supreme Court are whether or not a process must satisfy the particular machine or transformation test, and whether this test improperly excludes many business methods in spite of the wording of 35 U.S.C. 273, which specifically allows business-method patents. So far, the case has attracted legal filings from nearly every large company or group whose patents might be threatened. You can read briefs from Yahoo, IBM, Borland, Dolby Labs, the BSA, and many others, even one from some guy claiming to speak on behalf of the State of Oregon."
