MasterImage 3D Challenges RealD’s Intellectual Property Portfolio in the United States

MasterImage 3D, a worldwide leader in 3D display technologies for digital cinema, challenged the validity of four of RealD’s 3D polarization patents by filing five petitions for Inter Partes Review (IPR) with the United States Patent and Trademark Office. MasterImage 3D asserts that RealD’s patents claim to have invented techniques that have been well-known for decades and should never have been granted.
