GE Renewable Energy has filed a patent infringement complaint in the US against rival Siemens Gamesa.
GE has alleged that the German-Spanish company’s units infringe its patented low-voltage-ride-through and zero-voltage-ride-through technologies.
The US company said these “ensure that the wind turbines will pass ride-through certification”.
“It is GE’s view that the protection of intellectual property rights is the foundation for driving both innovation and investment in high technology industries generally, and the associated creation of high value jobs,” a spokesman said.
“GE believes strongly in the merits of its case against SGRE, and will continue to protect its technology in the US.”
The case has been taken to the US International Trade Commission and follows a number of similar claims taken by GE in the past.
Last year, the US manufacturer and Vestas settled a case on grid fault management software.
A statement from Siemens Gamesa said: “On 31 July 2020 General Electric Company filed a complaint against SGRE at the US International Trade Commission seeking an exclusion order against SGRE’s importation of wind turbine equipment into the United States, which has not been served yet and which we will be defending.
“We are confident that features and functionalities marketed by SGRE do not infringe any valid third parties’ intellectual property rights. Please understand that we cannot comment on this further due to ongoing legal proceedings.”
