CBS still wants to evict "The Glass House" from the airwaves.

The network moved ahead with its lawsuit against ABC this week by amending its filing that alleges ABC copied elements of "Big Brother" for its new reality TV competition series "The Glass House."

CBS attorneys added several more objections to the show now that ABC has aired several episodes, arguing that "`Glass House' employs the same plot, themes, mood, setting, pace, characters, dialogue, sequence of events and other concrete elements making up `Big Brother."'

CBS originally sought to stop "Glass House" from premiering in June, but a federal judge refused. U.S. District Judge Gary Feess agreed with ABC attorneys who argued that many of the filming techniques employed on "Glass House" are not unique to "Big Brother" and are used in other reality TV shows.

Both shows employ dozens of cameras to monitor a houseful of contestants vying for a cash prize, but Feess ruled the shows are likely to play out very differently.
