Amazon won a patent case against Rovi in the U.S. Court of Appeals for the Federal Circuit, according to CBR. Rovi, which sells television guide programs to cable providers, alleged Amazon had infringed two of its patents - one that covers making an electronic program guide on a television, and the other that covers allowing a user to select and purchase a pay-per-view program. Rovi had also filed lawsuits against Roku and Netflix, but the U.S. International Trade Commission ruled those companies did not infringe its patents.

Rovi worldwide intellectual property and licensing executive vice president Samir Armaly said the company was unhappy with the court's decision.

"It should be noted that this decision relates to only two patents in our extensive portfolio," Armaly said. "We believe that our portfolio is even more relevant to Amazon today and going forward than when the present litigation began in early 2011. Since that time, Amazon has continued to expand its video and over-the-top offerings through new products like the recently announced Fire TV."

Rovi indicated it plans to pursue further legal action in the future around these and similar patents, insisting this is to protect not only its own intellectual property but the business of its current licensees.
