According to the live bloggers at SCOTUSblog, the Court today issued rulings in four cases. Three—involving patent rights (Quanta Computer), the False Claims Act (Allison Engine), and RICO (Bridge)—were unanimous, and the fourth (Engquist), involving an equal-protection claim by a government employee, was 6-3, with Chief Justice Roberts writing the majority opinion and Justices Stevens, joined by Justices Souter and Ginsburg, in dissent. I’m headed out of town soon, but hope to find time to read through Engquist.

The Court has scheduled its next announcement session for this Thursday.
