I guess you need to seek the developers' country of origin not just US to claim copyright sues. If Lep's World Run is (one example) a Boguslavian game, Devsisters must file a lawsuit in Boguslavia, not South Korea. I'm not a lawyer nor anybody knows a lot about international law, but we never could really know which are copying and which are just improvising the previously known game - everybody has their own conceptions about it.
