I mean look,, the digiplayer used/uses Divx DRM with our MOS to encript; if we'v applied for a patent could divx be a part of it imo no.. well maybe, if said invention was devised to use variants of DRMs not just relying on one. IMO It has to be doing it alone, within a defined parimiter of gated substrates; a MicroOS controller with related circuitry that achieves encription where no man has gone before... lol, if it devoid of other DRM schemes. e
