On Tuesday, the European court of justice (ECJ) ruled vanHaren, a Dutch company, had infringed the brand's trademark by selling a range of red-soled shoes.
Louboutin started the legal action in 2012, when Van Haren brought out a range of shoes by actress Halle Berry which included high heeled shoes with red soles.
The battle was one by the designer and he seemed overwhelmed and thankful.
In 2014 the case was referred to the European court for clarification and past 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.
In February, Louboutin appeared to suffer a setback when the ECJ advocate general Maciej Szpunar said the combination of a colour and shape could be refused trademark protection. But the European court of justice disagreed, ruling that Louboutin's design "is not covered by the prohibition of the registration of shapes". Nevertheless, Christian Louboutin said in a statement today that it expects the court to confirm the validity of the mark fairly quickly.

The arcane legal dispute centred on whether Louboutin's trademark involved a shape or a colour.
Nevertheless, Van Haren had argued that the trademark in question was invalid - citing its connection to the shape of the shoe, an element that is not protected by European Union trademark law. "This decision is beyond appeal".
He said he expected the Dutch court to rule on the matter fairly rapidly.
