Court: Maersk Drilling infringed competitor’s patent

Maersk Drilling has lost an appeal case to its competitor Transocean meaning that Maersk Drilling will have to pay up USD 15 million, Maersk Drilling informs ShippingWatch.

The world’s largest operator of offshore rigs, Transocean, has won an appeal case against Maersk Drilling resulting in the Maersk Group operator of drilling rigs having to pay its competitor USD 15 million. The case was about a so-called dual activity technology making it possible for a single derrick on a rig to perform parallel drilling operations in order to save time and money, Maersk Drilling confirms.

In 2007, Swiss Transocean claimed that three of the company’s patents were infringed by the rig, Maersk Drilling had built for Statoil in the Gulf of Mexico. The following legal process has been long and in April 2011, an American judge overruled a jury’s assessment of the patents as being valid. This decision has now been reversed by the appeals court which has thereby expressed its agreement with the jury’s assessment meaning that Maersk Drilling will now have to pay its competitors USD 15 million.
