The United States of America automatically recognizes and protects a United States patent. That may not be the case in a foreign country. Therefore, a foreign application must be filed by a United States patent holder in a foreign country if they want patent protection. A US inventor or patent holder must also pay attention to the deadlines and requirements of a foreign application otherwise he/she might miss out on any chance of their patent being protected, either in the United States or a foreign country.
We at DeFrank.com are aware of the requirements/deadlines involved and have many procedures and practices in place so that none of these important dates are missed. All of our attorneys attend conferences and meetings, on a regular basis, to keep up up-to-date on filing foreign patent applications.
