W. R. Grace (GRA), through its wholly-owned subsidiary, Alltech Associates, filed a lawsuit in U.S. District Court for the District of Delaware against Teledyne Technologies (TDY), doing business as Teledyne Isco of Lincoln, NE, for infringement of four Grace U.S. Patents that cover its proprietary Reveleris X2 flash chromatography system. Flash chromatography is a process to separate target molecules and purify a product from a complex mixture in minimal time, an important step in a broad range of scientific applications. Grace introduced the Reveleris flash chromatography system in 2009, bringing new advanced capabilities to flash chromatography. Since then, Grace has been granted four Reveleris-related U.S. Patents, in addition to many industry awards.
