Celanese files patent infringement lawsuit against European distributor
Celanese Corporation announced that it has filed a patent infringement lawsuit in Poland against Falken Trade Polska sp. z o.o. sp.k., a distributor of Acesulfame Potassium, a high-potency sweetener subject to recently granted European Patent No. 2 861 569. The complaint alleges that the Distributor is selling infringing Ace-K sweetener produced by a Chinese manufacturer. Celanese claims compensation for damages caused by the sale of patent infringing Ace-K. Prior to filing this lawsuit, Celanese had successfully obtained a preliminary injunction against the Distributor preventing the Distributor from continuing to sell infringing Ace-K sweetener. In March 2017, Celanese announced that it had filed a patent infringement lawsuit in Europe against three Chinese manufacturers of high-potency sweeteners, specifically Acesulfame Potassium. The complaint alleges that Suzhou Hope Technology Co., Ltd., Anhui Jinhe Industrial Co., Ltd., and Vitasweet Co., Ltd., are infringing European Patent No. 2 861 569 by continuing to unlawfully import infringing Ace-K sweetener into Europe.
