Facebook sued over 'like' button

  • Facebook has been sued over its use of the "like" button and other features.

    The social network is being sued by a patent-holding company acting on behalf of a dead Dutch programmer called Joannes Jozef Everardus van Der Meer.

    A lawsuit was filed in a federal court in Virginia on Monday by Rembrandt Social Media.

    According to Rembrandt Social Media, Facebook's success was partly based on using two of Van Der Meer's patents without permission.

    Rembrandt now owns patents for technologies Van Der Meer used to build his own social network, called Surfbook, before his death in 2004.

    Van Der Meer was granted the patents in 1998, five years before Facebook’s debut.
