The claim comes from a German company called Medien Patent Verwaltung. According to new infringement lawsuits filed against Warners, Technicolor and Deluxe in New York and Germany, MPV says that in 2003, it introduced the studio to a method of marking films with a distinctive code so it could track back sources of piracy to the exact theater in which an unauthorized copy originated. MPV says it has been trying to get Warners to pay for use of the technology since it allegedly began incorporating the invention in prints throughout Europe in 2004.
