Jan. 10 will be D-Day for patent eligibility at the U.S. Supreme Court—”D” as in Decision.

The court has scheduled certiorari votes on three cases addressing Section 101 of the Patent Act that were highlighted earlier this month by Solicitor General Noel Francisco’s office. If the justices grant cert in any one—or, as a couple of petitioners are now suggesting, in two of the three—the court would be poised to rewrite or refine the most contentious area of patent law, or declare it settled once and for all.
