“As explained by the Court, the test serves as a proxy for assessing the more fundamental concern – ensuring that the claim does not seek to impermissibly “preempt the use of a fundamental principle.” This might make sense in the context of so-called business method patents, where the fundamental principle implicated is typically characterized as an abstract idea or mental process. But it is unclear to what extent this test will prove applicable to patent claims arising out of the life sciences, where patentable subject matter challenges more often allege preemption of a natural phenomena or law of nature, rather than an abstract idea or mental process.”
