The Eastern District of Texas, which in 2011 appeared to be losing its luster as the preferred U.S. district court venue for patent suits, regained its prominence in 2012, usurping the District of Delaware for the No. 1 spot, according to a new analysis by Perkins Coie partner James Pistorino.

EDTX saw 1,266 new patent cases filed in 2012 — more than triple the 418 suits it saw in 2011. At least some of this tremendous rise is attributable to changes brought about by the America Invents Act, the patent reform legislation that took effect in September 2011.
