(AP) -- A federal judge says a New York man who's suing for part ownership of Facebook can't have more time to produce documents and electronic media seen as important to his case.

Paul Ceglia of the western New York village of Wellsville was given until Monday to produce the materials. But his attorneys had asked the judge to delay that deadline, saying they needed more time. Facebook attorneys opposed the request, saying Ceglia was just trying to stall. On Friday, the Buffalo judge sided with Facebook and left Monday's deadline in place.

Ceglia claims he made a deal with Facebook founder in 2003 that entitles him to half ownership of the $50 billion social network. Zuckerberg says his dealings with Ceglia had nothing to do with Palo Alto, Calif.-based .
