What can we do if a manufacturer in China copied our US patented product and constantly sell their copies to US buyers through international E commerce platform? This Chinese company does not have a physical presence in the US. All transactions are captured through their website,payment method being used is PayPal, and they ship directly to buyers in the US via international EMS. As I understand, Patents are territorial rights. But do we have the legal right to go against them in this case? Since their copies are now flowing into the US market without the business entity sets foot in the US.
