That's not the only reason to file patents these days. A large percentage of patents filed by companes nowadays are never implemented. They're filed for strategic, legal, and financial reasons. Let's say Sony has no plans for DRM, but they hear that MS does. So they file a patent before MS does. Now if MS does implement a DRM system that infringes on the patent that Sony just filed, they either get sued or they have to pay Sony royalties to use that technology. It's especially common in the mobile phone industry where companies like Samsung and Apple and suing each other over patent infringement just about every other day.
