AUGUST 16, 2013 — Marine geophysical specialist Polarcus Limited (OSE: PLCS), which operates a fleet of eight advanced seismic vessels, says that it has today been advised that WesternGeco L.L.C. filed a lawsuit on August 15 against Polarcus US Inc and Polarcus Limited by way of complaint for patent infringement in the Southern District of Texas, Houston.
Polarcus says the alleged patent infringement relates to the same patents as are involved in the dispute between WesternGeco and ION Geophysical Corporation.
Polarcus says it has not yet received the official notification from the court of the Southern District of Texas.
Polarcus will review the complaint filed by WesternGeco with its lawyers and inform the market further in due course.
