Tate & Lyle has failed in its attempt to have Chinese manufactured competing products of its Splenda brand banned under patent infringements.
The US International Trade Commission ruled that companies bringing sucralose-based products to market had not illegally borrowed Tate & Lyle’s patented production processes for making it.
Splenda is sold as a low-calorie alternative to sugar and makes up around a quarter of Tate & Lyle’s income.
Tate & Lyle will appeal the decision in January. Its shares fell 11 per cent as a result of the decision.
