WB gets sued for pirating anti-piracy tech
The company, Medien Patent Verwaltung, claims that Warner Bros. has been using its unique source-tracking code in film prints since 2004. The code, created by MPV, allows pirated films to be traced back to their sources. Curiously, it seems that both MPV and Warner Bros. lay claim to patents called "Motion Picture and Anti-Piracy Coding," which makes the pending suit even more interesting.
