\"[a] claimed process is surely patent-eligible under § 101 if: (1) it is tied to a particular machine or apparatus, or (2) it transforms a particular article into a different state or thing.\" To avoid preemption the Federal Circuit emphasized that \"the use of a specific machine or transformation of an article must impose meaningful limits on the claim\'s scope to impart patent-eligibility;\" that \"the involvement of the machine or transformation in the claimed process must not merely be insignificant extra-solution activity;\" and that the transformation \"must be central to the purpose of the claimed process“

前一段查的资料,现在不知道怎么样了。
