A US patent holder can block importation and sale of an infringing machine, manufacture or composition of matter in the US and can sue for damages. You must seek to enforce your rights using the civil, administrative and criminal enforcement remedies available in that country.A patentee is typically unable to receive damages for products "manufactured, sold, and used abroad without ever entering the United States." A single international patent does not exist, so an owner will need to seek protection in each country individually. Patents are country-specific and are rights limited to the borders of the issuing country. Find the best patents attorney serving West Middlesex.
