TEMPE, Ariz., July 12 /PRNewswire-FirstCall/ -- A jury in the
patent infringement litigation in the United States District Court
for the District of Arizona
rendered a verdict last week that alumina-based and silica-based
tungsten Chemical Mechanical Planarization (CMP) slurries produced
and sold by DuPont Air Products NanoMaterials, LLC (DA
NanoMaterials) do not infringe Cabot Microelectronics' patents.
"We are extremely pleased with the jury's conclusion that DA
NanoMaterials' tungsten CMP slurries do not infringe Cabot's
patents," said Seng Wui Lim, chief
executive officer, DA NanoMaterials. "The ruling reinforces
the fact that our products are vastly different from Cabot's and
enables us to continue to aggressively pursue future business
growth regarding these products. We remain committed to
delivering innovative products, and will continue to compete in the
marketplace worldwide while providing our customers with superior
technology and service."
In addition to this court ruling, on June
18, the appellate Korean Patent Court found Cabot's tungsten
CMP Korean patent invalid. This continues a series of losses
by Cabot in Korean court cases finding Cabot's tungsten CMP patent
invalid, including invalidations in the Seoul District Court, the appellate Korean
High Court and the Korean Intellectual Property Tribunal.
