Why is this in particular more notable than the other thousands of companies suing for tariff relief? (In particular, V.O.S. Selections.)
Certain companies are well-known for their legal teams. Qualcomm is one (often described as a legal company that employs some engineers). Nintendo is the other. As a result, Nintendo's legal team is far more likely to ensure they get refunded, and quickly. They could provide a template for others to follow.
(EDIT: I just mean as a litigious company, well-known for its legal team.)
