Follow the source of this article (in this case Polygon, yuck) and you will find the original info:
It’s seeking $150,000 for each alleged violation of Nintendo’s rights outlined in the Copyright Act and $2,500 for each alleged violation of the Copyright Act’s anti-circumvention and anti-trafficking provisions. Alternatively, Nintendo also could elect to take “actual damages,” i.e. money it’s lost, and Keighin’s profits, “in amounts to be proven at trial.”
