An administrative law judge has ruled that Comcast and set-top vendors Arris and Technicolor have infringed on two patents belonging to TiVo.

Rovi Corp. complained to the International Trade Commission (ITC) in April 2016 that Comcast and its vendor partners were infringing on six patents related to digital video recording and interactive program guides.

According to Law 360 (sub. req.), ITC Judge David Shaw ruled that violations did indeed occur with two of the patents related to “interactive program guide with remote access.”

"This ruling reinforces the need for Comcast to take the necessary licenses to our intellectual property," TiVo told Law360.

According to TiVo, the patents relate to numerous features in Comcast's X1 video platform, including the way Comcast implements remote recording, the "AnyRoom" DVR and search.

The complaint was filed by Rovi right before it agreed to pay $1.1 billion to acquire TiVo. The merged company is now known as TiVo.

Rovi made 54% of its revenue in 2015 from the licensing of intellectual property.

Last year, Comcast replaced TiVo with Gracenote as the supplier of metadata services for X1. Insiders with knowledge of Comcast’s decision said the ITC complaint was a key influencer.
