After it sued AT&T (News - Alert) and Dish Network for patent infringement on licensing pacts valued at more than $1 billion, TiVo is now in the midst of another lawsuit – this time against Time Warner (News - Alert) Cable and Motorola Mobility, because of three more instances of patent infringement.

Motorola has been in a court battle as well against TiVo (News - Alert), right after it sued Verizon Communications, a company using Motorola's TV boxes for FiOS, one of Verizon's most sought-after offers.

At the moment, Motorola wants a non-infringement judgment with Verizon's (News - Alert) lawsuit. It turned around and said that TiVo has actually infringed three Motorola patents in its DVRs.

Earlier this week, TiVo counter-sued, arguing that Motorola (News - Alert) and Time Warner are guilty of infringing its patents.

TiVo alleges the infringement on the following three patents:

1. No. 6,233,389 – A "Time Warp" feature used by AT&T, Dish, and Verizon
2. No. 7,529,465 – Known as "System for Time Shifting Multimedia Content Streams"
3. No. 6,792,195 – Known as "Method And Apparatus Implementing Random Access And Time-Based Functions on a Continuous Stream Of Formatted Digital Data"

When asked to comment, Time Warner Cable refused. Motorola, however, said: "While we do not comment on pending litigation, Motorola Mobility will continue our vigorous defense against TiVo's infringement claims. We are confident in our position and believe we will prevail."

TiVo also made a statement: "Today, TiVo filed a response to a patent infringement suit that Motorola initiated against TiVo last year that was stayed until earlier this year. In our response, we have alleged counterclaims accusing Motorola and Time Warner Cable, one of Motorola's customers, of infringing three TiVo patents. We intend to diligently enforce our intellectual property rights."
