In August 2011, the U.S. Court of Appeals for the Second Circuit upheld a lower court’s ruling that anything that was manufactured overseas is not subject to the first-sale principle. Only American-made products or “copies manufactured domestically” were.
It would seem if the sum of foreign made products makes a new product, you would still need the permission of original manufacturers to resell it. Wonder if that could be stretched far enough to say foreign food spices at restaurants can no longer be used.
