Siemens Gamesa is to appeal an initial decision by the US International Trade Commission (ITC) that some of the manufacturer’s turbine technology infringes a GE patent.
A company spokesperson said that Siemens Gamesa is disappointed by the decision by an ITC administrative law judge that its turbines infringe GE’s low-voltage-ride-through technology patent (US 6,921,985).
“We reiterate our firm conviction that no features or functionalities marketed by the company infringe any valid third-party intellectual property rights,” the spokesperson said.
“In that regard, we intend to ask the full ITC Commission to review and overturn the administrative law judge’s initial determination on the 985 patent,” the spokesperson added.
However, Siemens Gamesa welcomed an initial determination by the ITC administrative law judge rejecting another GE claim against the company in regard to GE’s so called zero-voltage-ride-through patent (US 7,629,705).
The spokesperson added: “As these issues continue to be subject to legal actions in a number of jurisdictions – including our own affirmative action regarding the infringement of Siemens Gamesa’s offshore patents by GE scheduled for trial in Boston in April – we will not comment any further on the matter at this time.”
A GE Renewable Energy spokesperson said: “GE believes strongly in the merits of its case against Siemens Gamesa.
“We will continue to protect and defend our intellectual property, which drives innovation and investment in high technology industry, creating high value jobs.”
