Represent Comcast in a large number of inter partes review petitions filed to defend our client against a series of ITC and district court attacks by Rovi. The first series of IPRs against 15 patents led to the invalidity or dismissal in the litigation of every asserted claim in 14 of the 15 patents. The second series of IPRs filed against eight patents resulted in the invalidity of every claim in seven challenged patents, with Rovi asking the PTAB to cancel the claims in the eighth patent. In the third series of IPRs filed against eight patents, IPRs were instituted on every challenged claim of the eight patents. Final written decisions in the third series of IPRs are expected in due course. In a fourth series of IPRs filed against six patents, institution decisions are expected in October and November 2020.
