Rovi sues IMDb for TV Guide patent infringment

Rovi, previously known as Macrovision, have sued IMDb and its parent company, Amazon, for violating some of its patents. Rovi acquired the patents through their buy-up of Gemstar. The patents cover a wide range of features, including “interactive program guides” and “purchasing products on-demand to scheduling recordings from a computer”. Which means they might just as well sue Apple (iTunes), Microsoft (Xbox) and TiVo, and a whole bunch of other companies which have products that infringe on the patents.

However, Rovi claims that it has already struck a deal with Apple, among other, on licensing the patents. We’ll see how this one ends.
