Once a product is protected by a patent in the United States,the product will be protected from counterfeit by other countries due to international trade agreements.

A US patent does not automatically protect a product from counterfeiting in other countries. It is the responsibility of the patent holder to apply for and obtain patent protection in the countries where they wish to enforce their rights. Additionally, international trade agreements do not guarantee protection against counterfeiting, but they may provide mechanisms for addressing intellectual property disputes between countries.
