In some instances, yes. As a general rule, a patent is specific to the country where the patent is granted. A patent granted in the United States only prevents parties from selling, making or using the patented technology in the United States, or importing or exporting it or a substantial component of it into or out of the United States. Actions that take place entirely in a different country are typically not covered. However, there are some exceptions to this, such as if the alleged infringement involves a system, aspects of which take place in multiple countries but a significant part of the control and benefit of that activity takes place in the United States; or if the overseas activities induce infringement by another in the United States.
