RealD Wins Patent Lawsuits Against LightSpeed DepthQ

RealD has won a patent lawsuit against LightSpeed Inc.

German court rules in favor of RealD, finding LightSpeed DepthQ CineBright system infringed RealD’s 3D cinema projection system patents

London, UK ( July 12, 2022 ) -

A district court in Düsseldorf, Germany ruled in favour of global visual technology leader, RealD Inc., finding infringement of both asserted patents by the LightSpeed DepthQ CineBright two-beam system, it was announced today by RealD Inc.

The German court ordered a product recall and awarded injunctions, damages and costs against Lightspeed Inc., and LightSpeed’s directors, for infringing on RealD’s two-beam 3D cinema projection system patents (pat. numbers EP 2 469 336 and EP 2 067 066).

RealD’s patented light-doubling 3D cinema systems deliver the most light efficiency of any other 3D cinema projection technology, and as a result, provide a superior projected 3D image at lower operating costs.

The rulings apply to the European patents and are the latest cases upholding and affirming RealD’s patents around the world. Following a strong history of victories for RealD in numerous territories and regions including the United States, Europe China, Japan, Russia and Australia, where the company’s invention patents were successfully asserted, or challenges by infringers such as Master Image and Volfoni, were unsuccessful.

“RealD invests substantial resources in our mission to deliver the perfect visual image. To continue making such R&D commitments, we must hold infringers accountable for copying RealD’s patented technologies and are delighted this German court has done just that,” said Travis Reid, RealD’s Chief Executive Officer.
