Tivo will receive the minimum sum of $215 million over six years — more if AT&T DVR subscribers go above a certain level. This settles a patent dispute going back to 2009 and has been covered here with some side issues.
In addition to these minimum payments, AT&T will pay incremental recurring per subscriber monthly license fees through July 2018 should AT&T’s DVR subscriber base exceed certain levels.
As part of the settlement, TiVo and AT&T agreed to dismiss all pending litigation between the companies with prejudice. The parties also entered into a cross license of their respective patent portfolios in the advanced television field.
