A federal judge on Wednesday delayed ruling on whether to throw out a lawsuit filed against the founder of Facebook.com, saying he needed more information about allegations that Mark Zuckerberg stole the ideas of the creators of a rival social networking Web site.

Judge Douglas Woodlock gave ConnectU founders Cameron Winklevoss and Tyler Winklevoss — who are twin brothers — and Divya Narendra until Aug. 8 to flesh out their allegations against Zuckerberg, which include fraud, copyright infringement and misappropriation of trade secrets.
