In a filing on Friday afternoon in Manhattan federal court, Unilever said Ben & Jerry's board "is no ordinary board."
Ben & Jerry's could not immediately be reached for comment.
In August, a judge rejected Ben & Jerry's bid to immediately halt such sales.
Last month, Ben & Jerry's board renounced the sale of its ice cream by Zinger, saying his products "should not be confused with the products" made by Ben & Jerry's.
"The sale of products bearing any Ben & Jerry's insignia in the Occupied Palestinian Territory is against our values," the board said.
