Yes, trademark. I don't know what possessed me.

Playdoh recently managed to trademark its smell.

That's interesting, I thought the smell was a result of the ingredients - which would make it non-distinctive and unsuitable for a trademark (as others would be excluded from making the product so the trademark would operate as a perpetual patent).

Maybe the smell is a trademark only for other goods (I don't know what Class Playdoh falls in, toys?), eg Playdoh scented merch?
