RealD Wins All Three Patent Invalidation Challenges against Its 3D Projection Cinema Systems and Maintains All Three Invention Patents in China

The China National Intellectual Property Office has rejected all three Shenzhen LeVision's requests to invalidate RealD's Chinese patents
Shanghai, China ( January 24, 2024 ) -

Global visual technology leader RealD Inc. announced today that the China National Intellectual Property Office (CNIPA) has ruled in favor of RealD, rejecting all three Shenzhen LeVision Global Technology Co., Ltd.’s requests to invalidate RealD’s Chinese patents. LeVision’s three invalidity challenges to the RealD 3D dual-beam and the three-beam optical system patents were all rejected, confirming in full the validity and integrity of the invention patents of RealD 3D projection system in China.

RealD’s three Chinese invention patents are ZL201310233906.3, ZL201480000777.6, and ZL201710333855.X.

These patent challenges are the second time an individual or company has filed an invalidation request against patents owned by RealD 3D regarding their three-beam optical technology in China. All requests to date were denied.

This victory is also the latest case upholding and affirming RealD’s patented technology in the world. In 2018, the European Patent Office (EPO) rejected both Volfoni and MasterImage’s European patent invalidation challenges against RealD, and the validity, scope, and rights of RealD 3D system remained unchanged. Prior to this, RealD 3D was also challenged by patent invalidation challenges in jurisdictions such as the United States, Japan, Australia, and Russia, and these were rejected by local judicial and patent authorities. RealD’s invention patent rights on this technology have been maintained and reconfirmed time and time again.

In addition to maintaining the validity of the entire patent rights, RealD has also won verdicts of patent infringement against MasterImage, Volfoni, and DepthQ in both US and German courts over the past ten years.

“The success of these cases underscores the third-party recognition of the quality and value of our patents. They also reaffirmed the intellectual property behind RealD’s technology,” said Travis Reid, CEO and President of Worldwide Cinema of RealD.

“RealD employs world-class inventors and invests substantial resources in our mission to deliver the perfect visual image. In order to continue this commitment and invest in R&D, we must hold infringers accountable for copying RealD’s patented technology and protect our R&D and existing patented technologies,” Reid said.

RealD’s China subsidiary company was founded in 2010. “In the past ten years, we have established offices in Beijing, Shanghai, and Hong Kong, and in 2017, we established a Support Center in Shanghai to engage in product development and maintenance and gradually move the production base of 3D equipment to China. Along the way, we have built strong relationships with many cinema chains and cinemas, and together, we have brought better cinema experiences to moviegoers across China. The key to our business and partnership is the continuous research and development and the protection of our intellectual property rights,” said Edman Chan, Vice President and General Manager, Asia Pacific of RealD.

Since its introduction, the RealD 3D system has become the world’s most widely used cinema 3D projection technology. RealD’s patented technology delivers nearly double the light efficiency compared to other 3D systems, presenting brighter, better 3D images. Since 2006, RealD has established a strong patent barrier for 3D systems with nearly double the light efficiency. The intellectual property rights obtained by RealD cover the hardware structure, hardware design, and many inventive technologies of the system, and it has a total of more than 470 invention patents in countries or regions around the world, including China.
