Cabot Microelectronics' Patents Upheld in Patent Enforcement Action Against Dupont Air Products Nanomaterials, LLC
09 July 2010 - 11:06AM
Cabot Microelectronics Corporation (Nasdaq:CCMP), the world's
leading supplier of chemical mechanical planarization (CMP)
polishing slurries and growing CMP pad supplier to the
semiconductor industry, announced today that on July 8, 2010, the
validity of all Cabot Microelectronics' patents were upheld in the
company's ongoing patent enforcement litigation in the United
States District Court for the District of Arizona against DuPont
Air Products NanoMaterials, LLC ("DuPont Air Products
NanoMaterials").
The litigation began when DuPont Air Products NanoMaterials
filed an action seeking to invalidate certain Cabot
Microelectronics' patents and for a declaration of non-infringement
of them in December, 2006. It involves DuPont Air Products
NanoMaterials' manufacture and marketing of certain CMP slurries,
including those for polishing tungsten, that the company believes
infringe four patents owned by Cabot Microelectronics, which are
fundamental patents in the field of CMP. All of Cabot
Microelectronics' patents at issue in the case were found
valid. However, the jury found that DuPont Air Products
NanoMaterials' products at issue do not infringe the asserted
claims of these patents.
"We are pleased that the validity of all of our CMP patents at
issue in this case, which are core patents for tungsten and other
CMP polishing applications, has been upheld. However, we are
disappointed with the jury's verdict regarding infringement, and
are currently reviewing our legal options, including an appeal of
the verdict and moving for judgment as a matter of law," said H.
Carol Bernstein, Cabot Microelectronics' Vice President, Secretary
and General Counsel. "We remain committed to the enforcement
of our intellectual property and protection of our significant
investment in patent-protected research and development."
