A search for "asymmetrical spoon" gives a few that are shaped just like OP's. These ones look particularly close in shape. They also have sort of similar design around the handled ends - at least in that they have designs rather than a fully plain end.

OP doesn't say anything about the flatter side being thinner or sharper. I think if meant to cut into grapefruit or ice cream that side would be sharper/thinner. Absent sharpening, a pointy spoon should penetrate something easier than a less pointy one - and these look less pointy than if they were symmetrical. Plus, you'd bend those up pretty quick in hard ice cream I think. I think they're just asymmetrical for the sake of it, a point of distinction perhaps marketed as favoring right handed people in getting liquids off a flat surface better.
