ON MOTION
ORDER
Hy-Grade Valve, Inc. (HGV) moves without opposition to dismiss this appeal. The United States responds and requests that this court also vacate the decision of *968the United States District Court for the Northern District of Ohio.
On September 16, 2011, the President signed into law the Leahy-Smith America Invents Act, H.R. 1249, 112th Cong. (1st Sess.2011), amending 35 U.S.C. § 292 to eliminate the qui tam provision on which this action was predicated. This act included the following text regarding the effective date of this provision: “The amendments made by this subsection shall apply to all cases, without exception, that are pending on, or commenced on or after, the date of the enactment of this Act.” Leahy-Smith America Invents Act, Pub.L. No. 112-29 § 16(b)(4), 125 Stat. 284, 329 (2011) (“the Act”).
In light of the amendments to 35 U.S.C. § 292, this case is moot. Because the circumstance that rendered this case moot was the amendment of § 292(b) by Congress, it is appropriate to vacate the district court’s determination. 28 U.S.C. § 2106; see Alvarez v. Smith, — U.S. -, 130 S.Ct. 576, 581, 175 L.Ed.2d 447 (2009) (“Applying this statute, we normally do vacate the lower court judgment in a moot case because doing so clears the path for future relitigation of the issues between the parties/ preserving ‘the rights of all parties,’ while prejudicing none ‘by a decision which ... was only preliminary.’ ” (citing United States v. Munsingwear, Inc., 340 U.S. 36, 40, 71 S.Ct. 104, 95 L.Ed. 36 (1950))); Tafas v. Kappos, 586 F.3d 1369, 1371 (Fed.Cir.2009) (“Vacatur ... is appropriate if the mootness arises from external causes over which the parties have no control” (citing U.S. Bancorp Mortg. Co. v. Bonner Mall P’ship, 513 U.S. 18, 25, 115 S.Ct. 386, 130 L.Ed.2d 233 (1994))).
Accordingly,
It Is Ordered That:
(1) The motion is granted to the extent that the district court’s judgment is vacated and the case is remanded with instructions to dismiss the complaint.
(2) Each party shall bear its own costs.
