Facebook brings patent counterclaim against Yahoo


    By Dan Levine and Alexei Oreskovic

    SAN FRANCISCO (Reuters) - Facebook filed a counterclaim against Yahoo Inc on Monday for what it called patent infringement, based on 10 of Facebook's patents, according to a court filing.

    The counterclaim comes after Yahoo sued Facebook for patent infringement last month.
