The ruling also requires Süd-Chemie to discontinue the production, use or sale of organoclay products manufactured using the processes covered by Southern Clay Products patents. Southern Clay Products also said Süd-Chemie has been ordered to halt the manufacture of all organoclay products until it had removed process equipment affected by the ruling.
In a statement on the court decision, Süd-Chemie Inc. said it plans to appeal the judgment, adding that it has “taken all the necessary steps to initiate appeal proceedings and is confident that it will prevail in this dispute.” The statement said the company views the Southern Clay patents as being “invalid,” and said the patents have not been infringed.
Süd-Chemie also said the judgment “in no way” affects the ability of its Rheologicals business unit “to continue to produce and competitively supply all products for all customers.” Süd-Chemie Inc. is a supplier of rheological additives for paint and coatings. The company’s majority owner is Süd-Chemie AG of Germany.
