A court in Amsterdam has ruled that a character by Sanrio - a rabbit called Cathy - infringes the copyright of Miffy.
The ruling - widely reported last week - means that Sanrio has to immediately stop making, selling and marketing Cathy goods in the Netherlands, Belgium and Luxembourg.
If the ban is broken, Sanrio will have to pay 25,000 Euros a day, up to two million.
However, Sanrio has objected to the ruling, saying it does not "believe any copyright infringement took place, a view we intend to express legally. At this point, we believe any impact on company earnings will be limited".
