Patent battle over T&L sweetener

Washington DC: Tate & Lyle's American subsidiary Tate & Lyle Sucralose has filed a patent infringement case against three Chinese manufacturing groups and 18 importers and distributors. T&L says the firms infringed patented manufacturing technology for the product, which is marketed under the Splenda brand. "Our sucralose manufacturing technology is protected by a robust patent estate, which we will defend rigorously," said Robert Gibber, general counsel of Tate & Lyle.
