Tate & Lyle has lost its appeal against a group of Chinese manufacturers over an alleged infringement of its Sucralose patent.

The six-person International Trade Commission (ITC) in Washington DC upheld the initial ruling of an Administrative Law Judge of the ITC that deemed there had been no patent infringement.

“While this development is disappointing, intellectual property is just one of the many components which define Tate & Lyle’s formidable competitive advantage in the global sucralose business,” said Karl Kramer, president, Tate & Lyle Sucralose.
