Warner Bro. Accused of Pirating Anti-Pirating Tech

psycho12345 writes: German firm Medien Patent Verwaltung claims that in 2003, it revealed a new kind of anti-piracy technology to Warner Bros. that marks films with specific codes so pirated copies can be traced back to their theaters of origin. But like a great, hilariously-ironic DRM Ouroborus, the company claims that Warner began using the system throughout Europe in 2004 but hasn't actually paid a dime for it.
