General Electric Co. won a partial victory in its bid to use a U.S. trade agency to hobble Siemens Gamesa Renewable Energy SA’s wind business in the U.S. for the next year.

Siemens Gamesa infringes a GE patent that expires in May 2023 for a way to keep wind turbines connected to the grid during low-voltage events, the U.S. International Trade Commission said in a notice posted on its website Tuesday.
