EMGS wins patent battle



By Upstream staff 

A Dutch patent court has ruled in favour of Norwegian electromagnetic survey specialist EMGS in a case brought against it by seismic giant Schlumberger.

The court upheld EMGS's assertion that it is the inventor of sea bed logging and that EMGS was the first company to use electromagentism to directly detect oil and gas reservoirs.

It also stayed proceedings until a decision by the European Patent Office, which is expected within three to four years. Schlumberger launched the action in June last year.

EMGS boss Terje Eidsmo said in a statement: "EMGS confirms that three of its patents that are disputed by Schlumberger Holdings will remain valid.

"The court's decision is welcome, although it is not material in terms of our ability to deliver on our business strategy."
