Forgent Networks, which has so far garnered more than $100 million in fees on its so-called JPEG patent, is going after the digital video recorder industry.
The Austin, Texas-based maker of licensing and scheduling software owns four patents it claims give it the right to collect royalties on computers or similar devices, such as those made by market leader TiVo, that record, store and play back video- and audio-transmitted signals.
While three of the patents primarily involve videoconferencing systems, patent No. 6,674,960 specifically addresses recording television signals to a computer.
