The district court issued a
temporary restraining order on October 3, 2008 after the initial hearing of the case to prevent the sale and distribution of RealDVD. The temporary restraining order was turned into a
preliminary injunction against RealNetworks on August 11, 2009 by Judge
Marilyn Hall Patel, barring the manufacturing and distribution of RealDVD or any other similar software product after the court found that RealNetworks violated the DMCA and breached the CSS licensing agreement with DVD CCA.
DMCA claims on Content Scramble System The DMCA prohibits circumvention of "effective" access control of copyrighted works and the trafficking of tools that are designed primarily to circumvent "effective" access control or copy control of copyrighted works. RealNetworks alleged that that CSS is not effective anymore because it has been cracked or hacked. However, the court ruled that the DMCA statute does not require the access control or copy control technology to be strong as long as it prevents unauthorized access and/or copying under ordinary course of operation and with the authority of the copyright owner. Since the court concluded that CSS is still effective for ordinary uses, the DMCA claim against RealNetworks is valid.
Breach of license agreement RealNetworks argued that it fully complied with the CSS license agreement not only by preserving all of the associated protection but also by adding
Advanced Encryption System (AES) encryption to the copied content so that only the person who made the copy can play back the copied content with RealNetworks' player. However, the court decided that preserving the CSS protection only once during the initial playback of the DVD is not enough and any subsequent absence of CSS technology during the playback of copied DVD content from the hard drive is a contract violation. However, the court dismissed the claim because consumer can get the same hard drive copies through digital downloads, and some DVDs even come with an additional, non-CSS encrypted DVD that allows the users to copy the content onto the hard drive. Also, even if RealNetworks is able to obtain a license to circumvent CSS, RealNetworks still violated the DMCA for circumventing ARccOS and RipGuard. == Subsequent development ==
