EMGS to appeal Norwegian court's ruling on patent invalidity

EMGS to appeal Norwegian court's ruling on patent invalidity

As previously announced, Electromagnetic Geoservices ASA (EMGS) 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 United Kingdom, 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 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.
