GE is pursuing a fresh legal case against Siemens Gamesa alleging a patent infringement, the latest in a series of actions between the two turbine manufacturers.
The US company has lodged a claim with the UK Patents Court arguing infringement by the German-Spanish outfit.
The case, which was first filed on 29 December, involves offshore turbines.
“GE filed suit against Siemens Gamesa Renewable Energy Limited in the High Court of Justice of England and Wales raising claims of patent infringement,” said GE.
“The infringement action involves the UK part of EP 1 590 567 and certain offshore wind turbines. GE will not comment further on pending litigation.”
Siemens Gamesa said it will defend the case.
“Siemens Gamesa will be defending itself against any of the lawsuits and is confident that features and functionalities marketed by Siemens Gamesa do not infringe any valid third parties’ intellectual property rights,” a spokeswoman said.
The case is the latest in a string of claims and counterclaims involving the companies.
In late September, Siemens Gamesa filed a legal case against GE Renewable Energy alleging the latter’s Haliade-X offshore turbine infringes patents covering the German-Spanish manufacturer’s direct drive technology.
That was in response to GE launching a claim over the summer against Siemens Gamesa alleging that the latter’s turbines infringe the US manufacturer’s patented low-voltage-ride-through and zero-voltage-ride-through technologies.
