Macrovision's Patent Hedge
from the patent-everything dept
Over at the Constitutional Code blog, they've noticed an interesting combination of patents from copy protection firm Macrovision. Apparently, the company has patented both the concept of a P2P file sharing system and a way to stop copying on it. Certainly opens up all sorts of new possibilities for companies: patenting both the problem and the solution to an issue. Perhaps they're just learning from Microsoft. Of course, maybe this is similar to AT&T's decision a few years ago to patent spamming techniques. Either way, you have to wonder about the validity of that P2P patent, though, that's hardly stopped Macrovision in the past.
Thank you for reading this Techdirt post. With so many things competing for everyone’s attention these days, we really appreciate you giving us your time. We work hard every day to put quality content out there for our community.
Techdirt is one of the few remaining truly independent media outlets. We do not have a giant corporation behind us, and we rely heavily on our community to support us, in an age when advertisers are increasingly uninterested in sponsoring small, independent sites — especially a site like ours that is unwilling to pull punches in its reporting and analysis.
While other websites have resorted to paywalls, registration requirements, and increasingly annoying/intrusive advertising, we have always kept Techdirt open and available to anyone. But in order to continue doing so, we need your support. We offer a variety of ways for our readers to support us, from direct donations to special subscriptions and cool merchandise — and every little bit helps. Thank you.
