US patents have some extraterritorial effect. A party can be liable for patent infringement if it supplies components of a patented invention to a foreign country to be assembled there. In WesternGeco LLC v. ION Geophysical Corp., the US Supreme Court recently ruled, by a 7-2 majority, that damages can be recovered for lost profits in respect of foreign sales resulting from such supply.
