  • Marking fuel for authentication using quantitative and binary markers
    Patent number: 8592213
    Abstract: A first fuel and a second fuel are marked with a marker that can be detected quantitatively in a predetermined concentration range. The second fuel is marked with a binary marker. Decreased concentration of the quantitative marker, presence of a binary marker, or both may be indicative of a fuel that is altered (e.g., mixed, laundered, diluted, or adulterated). Testing a fuel includes testing the fuel for a presence of a first marker in the fuel in a predetermined concentration range, and testing the fuel for a presence of a second marker. The presence of the first marker in the predetermined concentration range and an absence of the second marker may be indicative that the fuel is unaltered. The presence of the first marker in the fuel in a concentration less than the predetermined concentration range or the presence of the second marker may be indicative that the fuel is altered.

  • Marking of products to establish identity and source
    Patent number: 5776713
    Abstract: In general, the invention features a method of marking a product for identification in which a marker, composed of a low molecular weight hapten covalently bound to a compound, is associated with the product. Where the marker is non-deleterious to the product, inert with respect to the product, and not already associated with the product. The invention also features hapten markers produced by covalently binding a hapten to a functional monomer and subsequently polymerizing the hapten-labeled monomer to form a hapten-labeled polymer.
