Jury Awards TriStrata $26.4 Million in Patent Infringement Case Against Mary Kay

Minneapolis (March 2005)– A jury in the U.S. District Court for the District of Delaware in Wilmington, Del., has found that Mary Kay Inc. infringed several patents owned by TriStrata Technology, Inc., and awarded TriStrata $26,359,405 in damages plus interest.  TriStrata's lead trial attorneys, Michael V. Ciresi and Jan M. Conlin of Robins, Kaplan, Miller & Ciresi L.L.P., said the 14 claims in the three patents at issue relate to alpha-hydroxy acid (AHA) skin care technology.

“The jury ruled in TriStrata's favor on all issues of infringement and validity,” said Ciresi, the Firm's chairman.  “This verdict reflects the value of the pioneering inventions of Dr. Ruey Yu and Dr. Eugene Van Scott in the field of skin care.”

“This five-day trial was a swift conclusion to a four-year patent battle.  TriStrata has licensed agreements with many skin care companies, for their pioneering advancements in products containing AHA as wrinkle reducers,” said Conlin.  “We are extremely pleased the jury recognized Mary Kay's infringement and awarded TriStrata with this substantial verdict.”

TriStrata is a wholly owned subsidiary of NeoStrata Company, Inc., a research-based dermatological company.
