Continuing to press for a temporary restraining order to keep ABC's "Glass House" from premiering Monday, CBS said Tuesday that ABC's lawyers had failed to point out any substantive differences between "Glass House" and CBS's long-running "Big Brother."
CBS asked for the order last week, arguing that "Glass House" has not only stolen the concept of "Big Brother" — 12 to 14 people live in a house where their moves are constantly monitored — but also poached former staffers from "Big Brother" and stolen production techniques.

ABC offered a series of defenses in a filing late Monday, but in its response Tuesday, CBS said none of them addressed its chief argument: that ABC's show had committed copyright infringement and stolen trade secrets.
