According to the Hollywood Reporter, Warner Bros. is being sued by Medien Patent Verwaltung for pirating their anti-pirating software.
“We disclosed our anti-piracy technology to Warner Bros. in 2003 at their request, under strict confidentiality, expecting to be treated fairly,” MPV says in a statement. “Instead, they started using our technology extensively without our permission and without any accounting to us. However, we had taken care to obtain patents to protect MPV’s technology, and we are now in a position where we must assert our rights.”
