A Walt Disney Co. unit asked a federal judge to block a bankruptcy court ruling that would allow another company to sell patents related to three- dimensional movies, Bloomberg News reported yesterday. Walt Disney Studios Motion Picture Production's rights to use the technology to convert traditional films into 3-D movies will be harmed, the company said in its appeal yesterday in U.S. District Court in Wilmington, Delaware. The dispute involves the shell company left in bankruptcy by the collapse of Digital Domain Media Group Inc., the provider of special effects for the movies “Transformers” and “Titanic.” That shell, known as DDMG Estate, held an auction for the patents last month that was won by RealD Inc. Disney claims it has the right to use the technology because of agreements it signed with the original patent holder in 2008 and 2009.
