The company welcomed the judgment, saying in a statement: "The protection of Christian Louboutin's red sole trademark is strengthened by the European Court of Justice".
Christian Louboutin has won a key legal case in a long-running battle to protect its signature red soles from copycats.
In 2014 the case was referred to the European court for clarification and previous year, advocate general Maciej Szpunar said in his advice to the court that it should find in Van Haren's favour in a complicated ruling about shape and colour.
Louboutin took Dutch shoe maker Van Haren to court in the Netherlands in 2012 after Van Haren sold similar shoes, with the Parisian designer insisting he had already registered the style in Europe. But the European court of justice disagreed, ruling that Louboutin's design "is not covered by the prohibition of the registration of shapes". Dutch judges referred the case to the EU's top courts for clarification on the bloc's trademark laws.
Elaine O'Hare, an intellectual property specialist at the law firm Stevens & Bolton, said: "The ECJ has not followed the recent recommendation of the advocate general and has instead ruled that Louboutin's red soles can in fact be protected as a trademark".

The arcane legal dispute centred on whether Louboutin's trademark involved a shape or a colour.
The Dutch company took the case to the EU court citing European regulations that shapes by themselves can not be registered as trademarks.
Christian Louboutin COO and GM Alexis Mourot told WWD that today's European Union ruling confirms the registration of the brand for all of Europe.
Experts said the decision, which will be delivered by a court in The Hague, is a victory for brands hoping to protect their products against cheap rip-offs.
