Celanese Files Patent Infringement Complaint with U.S. International Trade Commission Seeking Exclusion of Certain High-Potency Sweeteners

Unlawful importation of Ace-K sweetener from China violates Celanese patent

DALLAS--()--Celanese Corporation (NYSE: CE), a global technology and specialty materials company, today announced it has filed a complaint with the United States International Trade Commission (ITC) in Washington, D.C., seeking an investigation of the unlawful importation into the United States of artificial sweetener Acesulfame Potassium (Ace-K) products that infringe upon United States 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. These manufacturers have been notified of their infringement of the asserted patent by the filing of this complaint with the ITC.

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.

Celanese intends to protect these investments to support customers with quality engineered products, and the company intends to vigorously defend its patented technology against unlawful importation and uses in the United States.

Further details of today’s filing will be available in the coming days on ITC’s website at www.usitc.gov and in the Federal Register at www.federalregister.gov.
