What is the difference between a U.S. patent and a foreign patent?

Patents are a form of intellectual property (IP) protection that gives exclusive rights to inventors for new and useful products. In the United States, a U.S. patent is granted by the United States Patent and Trademark Office (USPTO). A patent gives an inventor exclusive rights to make, use, and sell the invention across the United States. A foreign patent is a patent that is granted by foreign governments, such as the European Patent Office (EPO) or the Japan Patent Office (JPO). The main difference between a U.S. patent and a foreign patent is the scope of protection. A U.S. patent only provides protection within the United States and its territories. This means that if someone outside of the United States infringes on an inventor’s patent rights, they can only be held liable in the U.S. legal system. However, a foreign patent gives the inventor protection over their invention in the countries where the patent is granted. This means that if someone outside of the United States infringes on a foreign patent, the inventor can pursue legal action in the court system of the country where the patent is granted. The other main difference between a U.S. patent and a foreign patent is the application process. A U.S. patent application is submitted through the USPTO, and a foreign patent application is submitted through the particular foreign patent office of the country in question. Additionally, the application fees, requirements, and turnaround times vary from country to country. Overall, U.S. patents provide protection within the United States and its territories, while foreign patents provide protection in the countries where they are granted. Both require a different application process, fees, and requirements, depending on the country.
