PASADENA, CA | Posted on February 12th, 2007

"The dip pen nanolithography project was one of the first to be sponsored by Arrowhead, and we have worked with Dr. Collier and Caltech to patent the inventions generated under the agreement," said R. Bruce Stewart, Chairman of Arrowhead. "We intend to continue to license Arrowhead's new technologies when the economics make sense, in addition to commercializing products through our subsidiaries."

"Our license from Arrowhead Research Corporation, coupled with several recently awarded patents, is helping to protect and strengthen NanoInk's intellectual property portfolio," said Dr. Cedric Loiret-Bernal, NanoInk's Chief Executive Officer. "This intellectual property will play a critical role as we continue to explore the applications of our DPN technology to drive the development of high value end products."

The licensed patent application covers techniques related to use of surfactants to support NanoInk's Dip Pen Nanolithography® (DPN®) technology. Dip pen nanolithography involves deposition of nanoscale materials onto a substrate for applications in the life sciences and semiconductor industries.
