Celanese Corporation (NYSE: CE), a global technology and specialty materials company, today announced that the U.S. International Trade Commission (USITC) has voted to institute an investigation into the unlawful importation into the United States of certain high-potency sweeteners, specifically Acesulfame Potassium (Ace-K), in response to the company's recently filed complaint with the Commission. The investigation centers on alleged violations of section 337 of the U.S. Tariff Act of 1930 in the importation into the United States of high-potency sweeteners that are alleged to infringe U.S. Patent No. 9,024,016, owned by Celanese. Celanese contends a number of Ace-K manufacturers have unlawfully introduced sweeteners made via Celanese's patented technology from China into the United States market. In the investigation, the Commission will consider a general exclusion order barring the importation of all infringing sweeteners. Celanese continuously invests in manufacturing and quality improvements and is dedicated to robust research, development and customer support for the sweetener products manufactured by its patented process. The company intends to protect these investments to supply customers with quality engineered products, and intends to vigorously defend its patented technology against unlawful importation and uses in the United States.
