Lars Erickson v. Michael John Blake (D. Or.)

On Pi day 2011, NPR ran a radio story featuring Michael Blake’s YouTube video titled “What Pi Sounds Like.” Less than a month later, Blake was sued for copyright infringement by Lars Erickson who copyrighted a work called the “Pi Symphony” in 1992. Klarquist filed a motion to dismiss. On Pi day, March 14, 2012, Judge Michael Simon granted Blake’s motion to dismiss, finding that Erickson was impermissibly attempting to extend his copyright to cover the idea of creating a musical work based on the number Pi.
