Apple is seeking to force three Mac rumor sites to turn over information about the person who leaked details on a forthcoming music product. “Apple last week was granted the right to subpoena Powerpage.org, Apple Insider and Think Secret, forcing the sites to turn over all documents related to an unreleased product code named ‘Asteroid’ and ‘Q97,'” reports CNET News.com. “In November, Apple Insider and Powerpage.org reported that Apple was developing what’s known in the music industry as a breakout box–a device for connecting musical instruments and other analog audio sources to a computer. Earlier this month, Apple filed suit in Santa Clara County Superior Court against the unnamed persons it says released company trade secrets but added in later court filings that it has been unable to determine who those people are. The subpoenas, Apple said in its filings, are designed to identify the individuals.”
