This isn't a valid trademark. If it's ever challenged, it's doomed. The fragrance industry has already been down this road: you cannot copyright/trademark/patent a smell, you can only protect the composition of your formula. USPTO has an entire classification system that deals with perfume patents, so I have no idea how this trademark got approved.

If someone duplicates your fragrance without duplicating your formula, they are free to do so, even for profit (See: The "Replica" brand of fragrances).

If they want to protect this smell as a form of IP, they need to patent their formula, not trademark a description of the scent. Even then, so long as competitors don't copy the formula, they are free to copy the smell.
