Google will face off against the United States government in a federal court on Feb. 22 over whether the Department of Justice can force the search giant to turn over records from its database.
The conflict stems from a subpoena demanding information on searches, which Google refused to comply with, citing privacy concerns.
The government is attempting to gather data to support a child protection law that was struck down two years ago by the U.S. Supreme Court.
Under that law, the government could punish pornography sites that made content easily accessible to minors.
Google competitors Yahoo, AOL and MSN have already turned over search data to the government.
However, Google contends that supplying the information would violate the privacy of its users, as well as divulge trade secrets that could help its competitors.
