I don't know very well how patents and intellectual property protection work... But, if there are no suppliers of such a product in the United States (assuming your previous argument as true), then what product is being pirated? if there is none (worth the redundancy), to my understanding, there has to be a vendor whose product is being counterfeited within the united states for it to be taken as an infringement of intellectual property.
Other than that, you were not entitled to a trial? They just confiscated everything and there it ended?
