On January 21, 2010, the International Trade Commission issued a notice deciding to extend the target date for completion of the investigation in Certain Semiconductor Integration Circuits Using Tungsten Metallization and Products Containing Same (Inv. No. 337-TA-648).

By way of background, the Complainants in this investigation are LSI Corporation and Agere Systems Inc. and the Respondents are Tower Semiconductor, Ltd., Jazz Semiconductor, Powership Semiconductor Corporation, Grace Semiconductor Manufacturing Corporation, Integrated Device Technology, Inc., Spansion, Inc., and Nanya Technology Corporation.  On September 21, 2009, ALJ Carl C. Charneski issued an initial determination (“ID”) finding no violation of Section 337.  On November 23, 2009, the Commission issued a notice determining to review-in-part the ID finding no violation of Section 337 and determining to remand a portion of the investigation to ALJ Charneski.  See our November 30, 2009 post for more details.  On January 15, 2010, ALJ Charneski issued a remand ID finding that claim 4 of U.S. Patent No. 5,227,335 was not rendered obvious by IBM Process A and other prior art.

In the January 21 notice, the Commission “determined to extend the target date for completion of the investigation to March 22, 2010.”
