PTAB sides with Comcast in TiVo IPR

2018/09/13

The US Patent Trial and Appeal Board (PTAB) delivered a blow to entertainment group TiVo Corporation in its ongoing patent dispute with telecoms company Comcast Corporation.

In a final written decision delivered (pdf) on Friday, September 7, the PTAB said that Comcast had shown claims 1 to 16 of a TiVo patent to be unpatentable “by a preponderance of the evidence”.

At the start of 2018, TiVo filed lawsuits against Comcast in multiple US states. The entertainment group alleged that Comcast had infringed a number of patents related to interactive programme guides, digital storage, transport control interface, and content access.

In April 2016, Rovi (as it was known then) brought an enforcement action against Comcast at the US International Trade Commission (ITC). The ITC found in November 2017 that Comcast’s set-top box infringed two of the patents in question.

In March, in a separate matter, the ITC said it would investigate Comcast based on TiVo’s allegations of patent infringement.
