Bilski is an important patent case decided by the U.S. Supreme Court on June 28, 2010, and which for the first time addressed the validity of so-called "business method" patents. The inventors in that case tried to patent a method of hedging risks in commodities trading, but the Supreme Court denied their application by ruling that the process they were trying to patent was too abstract. At the same time, the Supreme Court left the door open to other types of business method or process patents by rejecting the claim that an invention is patentable only if it (1) is implemented with a particular machine or else (2) transforms an article from one thing or state to another. The Supreme Court did not attempt to set parameters for this so-called "machine or transformation test," but instead ruled that this test is only "a useful and important clue" to patentability. Shortly after Bilski was decided, the U.S. Patent and Trademark Office issued a set of interim guidelines to its patent examiners, effective July 27, 2010, for applying Bilski to method or process patents like the AVS Technology
®. These guidelines were in effect when the latest patent in the AVS Technology
® portfolio (No. 7,788,143) was granted on August 31, 2010. This means that Patent Office believes that the '143 Patent is fully consistent with the Bilski decision.
