New submitter sed quid in infernos writes "The Supreme Court issued a unanimous opinion yesterday holding that 'to transform an unpatentable law of nature into a patent-eligible application of such a law, a patent must do more than simply state the law of nature while adding the words "apply it."' The Court invalidated a patent on the process of adjusting medication dosage based on the levels of specific metabolites in the patient's blood. The opinion sets forth a process for determining patent eligibility for patent claims that include a law of nature. The court wrote that the "additional features" that show an application of the law must "provide practical assurance that the [claimed] process is more than a drafting effort." This language suggests that the burden will be on the patentee to prove that its limitations are more than patent attorney tricks.'"
