TiVo protects rights to patents by using them to countersue DVR maker Cisco
Very soon after Cisco sued TiVo to challenge TiVo's claims to patents used in DVRs, TiVo has gone ahead and sued Cisco back. According to a Tuesday report, there are four patents in contention and TiVo is involved in several lawsuits against a number of companies that bought the allegedly offending DVRs from Cisco. Cisco's Scientific Atlanta arm sells boxes to cable providers that include AT&T, Time Warner Cable, and Verizon Communications.
