ITC Rescinds Exclusion Order Against Sinorgchem

Filed under: Rubber Chemicals — Notch @ 12:55 pm

Rubber & Plastics News reported on Wednesday that the US International Trade Commission has rescinded the limited exclusion order barring the sale of rubber antidegradants manufactured by Sinorgchem Co. Shandong in the United States. The chemicals were sold through Sovereign Chemical Co. The ban covered 4-ADPA produced by Sinorgchem, as well as 6PPD produced from the disputed 4-APDA, whether by Sinorgchem or others.

The ban was instituted in July 2006 in response to a complaint filed by Flexsys America LP in early 2005. Last December, a federal appeals court reversed and remanded the finding that Sinorgchem had directly infringed on the Flexsys patents, which led to the decision to rescind the limited exclusion order issued at that time.
