Question: If I have something that I've patented how does that carry over into other countries?
Question Detail: I got the patent in the US but I want to see if there is a market for my product in other countries. Do I have to get patents for it in every country I want to sell in?
Answer: Your US patent only provides protection in the US. But if your US patent has actually issued as a patent, then it would be too late for you to file patent applications in foreign countries.
