Celanese Sues Chinese Sweetener Competitors in Europe for Patent Infringement, Seeks Additional U.S. Patent Rights

DALLAS--()--Celanese Corporation (NYSE: CE), a global technology and specialty materials company, today announced that it has filed a patent infringement lawsuit in Europe against three Chinese manufacturers of high-potency sweeteners, specifically Acesulfame Potassium (Ace-K). The complaints allege that Suzhou Hope Technology Co., Ltd., Anhui Jinhe Industrial Co., Ltd., and Vitasweet Co., Ltd., are infringing newly granted European Patent No. 2 861 569 by continuing to unlawfully import infringing Ace-K sweetener into Europe. The ’569 patent is directed to improved production processes for making its Sunett® Ace-K sweetener.

In a temporary shift in focus, Celanese has withdrawn its complaint from the U.S. International Trade Commission (ITC) and requested the U.S. Patent and Trademark Office review additional claims to its already-patented and improved Ace-K manufacturing process described in U.S. Patent No. 9,024,016.

Celanese continues to invest in manufacturing and quality improvements and is dedicated to robust research, development and customer support for the Sunett® sweetener products manufactured by its patented processes. The company will protect these investments to supply customers with quality engineered products, and will vigorously defend its patented technology against unlawful importation and uses in the United States, Europe, China and globally.
