NEW YORK CITY, USA/HAAG, Switzerland: The Swiss company Sulzer Mixpac has filed another lawsuit at a U.S. District Court in New York against the Seil Global Corporation based in South Korea. In the complaint, the manufacturer of the Mixpac S-system is accusing Seil to have infringed patents with their range of mixing tips suitable for two-component applications systems used in dentistry.

The lawsuit is the latest in a year-long juristic battle involving both companies. Sulzer filed its first complaint against Seil during the Greater New York Dental Meeting in November 2008. Other lawsuits ruled in favor of the company in November 2010 and September this year.

Despite changes to the tip design introduced in 2010 and a temporary restraining order issued by the court that prohibits Seil from importing and selling its mixing tips in the U.S., Sulzer claims that its patents are still being infringed.

A decision by the court is expected in the upcoming weeks. According to representatives of the Greater New York Dental Meeting, Seil has registered again for the next exhibition to be held from 27 to 30 November in New York City.
