LOS ANGELES (AP) -- ABC is urging a judge to reject an attempt by rival network CBS to block next week's premiere of a new reality series called "The Glass House."

CBS claims the new show copies key elements of its popular series "Big Brother" and is relying on the experiences of dozens of its former staffers to create the new show.

ABC's filing Monday in a Los Angeles federal court says the network has spent $16 million promoting "Glass House" and delaying its June 18 premiere could cost nearly 150 people their jobs.

The network's attorneys also claim most of the things CBS argues are trade secrets are not unique concepts, but rather standard elements of reality television.

The filing states "Glass House" contestants rely on audience approval, unlike "Big Brother."
