A British court has ruled in favor Hasbro, the makers of the iconic toy, Play-Doh.
That's spelled P-l-a-y - dash - D-o-h.
Hasbro sued a German company for trademark infringement.
The company makes a product called Yummy Dough and used the phrase "play dough" on its label, using the conventional spelling.
The German company posted a statement on its website saying it's disappointed by the ruling.
Company officials say they're considering their options, including an appeal.
