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.
