Did the seller happen to be based in your country? It seems unlikely to me the FTC would do anything about an online purchase to begin with, especially not if it was from China.
The US has an International Trade Comission that does seize counterfeit imports and those that violate trademarks without being deceptive clones. They aren't going to do much for one unit, but if an importer is bringing in container loads, then they may exercise the authority.
