DuPont Air Products NanoMaterials
L.L.C. (DA NanoMaterials) remains confident in its legal positions following
the judge's order denying all summary judgment motions in DA NanoMaterials'
patent invalidity/non-infringement lawsuit against Cabot Microelectronics currently
under way in the U.S. District Court for the District of Arizona.
The judge in the case denied summary judgment motions from both DA NanoMaterials
and Cabot, including Cabot's claim that DA NanoMaterials infringed Cabot's tungsten
chemical-mechanical planarization (CMP) patents. The Court has ordered the parties
to submit pre-trial filings by December 16, 2009.
The denial of Cabot's summary judgment motion, coupled with a recent invalidation
judgment rendered by Korean governmental authorities invalidating Cabot's tungsten
CMP patent in Korea, strengthen DA NanoMaterials' position. DA NanoMaterials
remains committed to its innovative and patented products. The company looks
forward to defending its products in this U.S. lawsuit against Cabot and continuing
to compete in the marketplace worldwide with its superior technology and customer
