MPEG LA, LLC today announced that several patent holders in MPEG LA?s MPEG-2 Patent Portfolio License have sued Lenovo or infringing patents essential to the MPEG-2.

The seperate patent enforcement actions have been filled in the United States District Court for the Southern District of New York and Landgericht D?sseldorf against Lenovo Group Limited, Lenovo (United States) Inc. and Lenovo (Germany) GmbH, MPEG LA said in a statement.

The related patents are essential to the MPEG-2 digital video compression standard used worldwide in digital television broadcasting and DVD.

According to the complaints, Lenovo offers in the United States and Germany products, such as desktop computers, laptop computers, Blu-ray Disc drives, DVD drives and software, which use patent protected MPEG-2 methods without having entered into licenses with the individual patent holders or a portfolio license that includes these patents offered by MPEG LA.

The suit seeks, among other things, monetary damages and an injunction prohibiting Lenovo from using MPEG-2 patents in its products and from offering, marketing, or importing them.
