GE on Monday unveiled in a court filing two new versions of its Haliade-X offshore wind turbine that it says don’t include patented technology at the heart of litigation with Siemens Gamesa and subject to a US sales ban.

GE Renewable Energy was prohibited from selling its flagship machine in the American market after a court found last month it violated a Siemens Gamesa patent, but the OEM claimed that it had alternative designs that exclude the offending technology and could be offered.
