WASHINGTON, D.C. - A February 2012 ruling by the Federal Circuit U.S. Court of Appeals that patents are not exhausted as to products that are manufactured and sold in a foreign country remains intact, thanks to a March 25 denial of certiorari by the U.S. Supreme Court (Ninestar Technology Co. Ltd. et al. v. International Trade Commission et al., No. 12-552, U.S. Sup.).
