On March 27, 2007, with the help of an intellectual property attorney, two students from McLean High School in Virginia (with assistance from the Committee For Students' Rights) and two students attending Desert Vista High School in Phoenix, Arizona, filed suit in United States Circuit Court (Eastern District, Alexandria Division) alleging copyright infringement by iParadigms, Turnitin's parent company. Nearly a year later, Judge Claude M. Hilton granted summary judgment on the students' complaint in favor of iParadigms/Turnitin, because they had accepted the click-wrap agreement on the Turnitin website. The students appealed the ruling, and on April 16, 2009, the United States Court of Appeals for the Fourth Circuit affirmed Judge Hilton's judgment in favor of iParadigms/Turnitin.
