Tessera Technologies Inc. has filed a new patent infringement complaint against several companies with the U.S. International Trade Commission (ITC). Tessera also has filed a concurrent action in the U.S. District Court for the Eastern District of Texas against these same companies. The company is seeking to investigate the unlawful importation of certain small-format BGA semiconductor packages and products.

The companies named as respondents in this ITC complaint include A-Data Technology, Acer Inc., Acer America, Centon Electronics, Elpida, International Products Sourcing Group, Kingston Technology, Nanya Technology, Peripheral Device and Product Systems, Inc., Powerchip Semiconductor, ProMOS Technologies, Ramaxel Technology, SMART Modular, and TwinMOS Technologies.

The complaint seeks an exclusion order barring the importation, sale for importation or sale after importation of products that Tessera believes infringe its technology and are unlawfully competing with products from Tessera's licensees.

The ITC is expected to decide whether to initiate an investigation under the complaint within 30 days. Tessera also has filed a concurrent action in the U.S. District Court for the Eastern District of Texas against these same companies.

In both the ITC and district court complaints, Tessera seeks remedies for infringement of U.S. Patents 5,679,977; 6,133,627; 5,663,106; and 6,458,681. The 5,679,977 and 6,133,627 patents have been litigated in prior Tessera legal actions. All four patents are part of a portfolio of technology that is broadly licensed to companies in the semiconductor industry including leading DRAM manufacturers Samsung, Hynix, Qimonda and Micron.

In May 2007, the ITC instituted an investigation regarding infringement of Tessera's patents by Qualcomm, Freescale, Motorola, ATI Technologies, Spansion, Spansion LLC, and ST Microelectronics.
