Yes. The United States has expressly waived its immunity to suit for
copyright infringement. 28 U.S.C. 1498.
For some time, it was unclear whether the Eleventh Amendment of the U.S.
Constitution operated to make a state immune from suit for copyright
infringement. In BV Engineering v. University of California at Los
Angeles, 858 F.2d 1394 (9th Cir., 1988), UCLA successfully defended a
copyright infringement suit on the ground that it had such immunity.

governments of each state may be sued for copyright infringement, and may
not plead immunity as a defense.
