W. R. Grace & Company Files Flash Chromatography Patent Infringement Suit Against Teledyne Isco

Columbia, MD – March 25, 2013 – On March 15, 2013, W. R. Grace & Co. (NYSE: GRA), through its wholly-owned subsidiary, Alltech Associates, Inc., filed a lawsuit in U.S. District Court for the District of Delaware against Teledyne Technologies, Inc., doing business as Teledyne Isco of Lincoln, Neb., 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.

“Patent protection is absolutely essential in a marketplace that values innovation. Companies like Grace, who invest heavily in research and development, can only create the products customers demand if a return on that investment can be assured,” said Laurie Andriate, Vice President/General Manager of Grace’s Discovery Sciences group.
