TiVo Bulks Up Interactive TV Patents
No Comments
TiVo announced late Wednesday it had purchased six patents covering interactive television from IBM, giving the digital video recorder maker a total of 76 United States patents. The new additions specifically cover audience measurement, integration of Internet with TV, and content searching, TiVo said.
The patents were originally filed for an IBM digital video group that no longer exists, and also include information searches and enhancements to the electronic program guide. Patents have become a critical asset in the technology industry these days, and TiVo has previously sued satellite TV provider Echostar for infringement.
