My last post focused on definitions for the terms “well-understood,” “routine,” and “conventional”—or W-URC—from the subject matter eligibility test set forth in Mayo and further described in Alice. Those terms relate to one part of the current test only. It seems fair to consider another important term in the test, one that’s considered before even reaching the W-URC issue: Whether the claim is “directed to” patent-ineligible subject matter, e.g., a law of nature.
I was particularly reminded of the need to address this when reading last week’s Federal Circuit opinions in Vanda Pharmaceuticals v. West-Ward Pharmaceuticals. Not only did Judge Prost pen a stark dissent from Judge Lourie’s opinion for the court, but both the majority and dissenting opinions focused on this phrase over and over. The opinion of the court referenced “directed to” 17 times and the dissent used it 10 times. Further, the phrase was used either in italics or quotes five times, emphasizing the importance of the term. So it’s worthwhile to give a look to what “directed to” means.
