    EMGS to appeal Norwegian court's ruling on patent invalidity

    Company News // March 3, 2015

    Electromagnetic Geoservices (EMGS) has confirmed that it has issued claims against Petroleum Geo-Services (PGS) in the High Court of Justice, Patent Court, in London, UK, and in Norwegian courts on the basis that PGS used its Towed Streamer EM in the territory of the UK, Ireland and Norway in violation of one of EMGS' patents.

    On 13 February 2015, EMGS received the decision of the Oslo City Court where EMGS' patent is found to be invalid. EMGS has decided to appeal the decision.
     
    EMGS successfully defended the patent against claims of invalidity from Schlumberger Holding Ltd in the Netherlands, in February 2008 and in the UK Court of Appeal in July 2010 and through several oppositions in the European Patent Office appeal division in December 2011.

    The company said the decision of the Oslo City Court on validity of this patent is contrary to these previous international decisions, all made by specialized patent judges. The patent remains valid in 23 countries.
