|Cabot Microelectronics' Patents Upheld in Patent Enforcement Action Against Dupont Air Products Nanomaterials, LLC|
AURORA, Ill., Jul 8, 2010 (GlobeNewswire via COMTEX) --
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."
