Grace files flash chromatography patent infringement suit

On 15 March 2013, WR Grace & Co, through its wholly owned subsidiary Alltech Associates, filed a lawsuit in the US District Court for the District of Delaware against Teledyne Technologies, doing business as Teledyne Isco, for infringement of four Grace US 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 advanced capabilities to flash chromatography. Since then, Grace has been granted four Reveleris-related US 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.
