Google Inc. 's Motorola unit confirmed that it has reached an agreement to settle patent litigation with set-top box maker TiVo Inc.

The terms of the settlement weren't immediately disclosed, but the agreement marks another end to TiVo's continuing patent litigation efforts with its larger rivals.

TiVo, based in Alviso, Calif., popularized TV-connected digital-video-recording devices. It has been largely successful in its protracted legal battles against larger rivals it said are making competing devices that infringe its patents. Two years ago, for example, Dish Network Corp. and its former unit EchoStar Corp. agreed to pay TiVo $500 million to settle their seven-year patent dispute. In January 2012, the company also got at least $215 million as part of a settlement with AT&T Inc.

The patents TiVo initially sued Motorola over included technology encompassing a digital video recording and playback device and methods for more efficiently playing recorded video.

A spokesman for TiVo declined to comment about the case, as did two of the clerks for the U.S. District Court for the Eastern District of Texas, where the case was being heard. No settlement papers had appeared by Thursday afternoon in files for the case that have been made public online.
