Executives at CBS sued ABC in May with copyright infringement claims against The Glass House, which they deemed too close in concept to Big Brother.
The Huffington Post reports that a Los Angeles judge dismissed CBS's move to block the broadcast of the reality show in a court hearing on Friday (June 22).
Judge Gary Feess stated that the show did not meet the requirements of copyright infringement due to the unpredictable nature of reality television.
He added: "Until the cameras begin to record, there is no plot, there is no [dialogue], there is no pace or sequence of events, and there are no fixed characters because there is no author.
"There is a setting, which is hardly novel, and some general ideas regarding the structure of the show, but little else."
CBS has plans to continue pursuing the case, arguing that almost 30 Big Brother production members are working on The Glass House, which apparently violates confidentiality agreements.
Last week the network issued a sarcastic press release about its 'development' of a reality series called Dancing on the Stars, a parody of ABC's Dancing with the Stars.
