SAN JOSE – Tessera Technologies has filed a new complaint requesting the U.S. International Trade Commission investigate the unlawful importation, sale for importation and sale after importation of certain small-format BGA semiconductor packages and products including these packages.
 
Tessera’s complaint is directed at a variety of products, including certain DRAM memory chips, DRAM memory modules and computer systems incorporating such chips and modules.
 
Companies named as respondents include A-DATA Technology, Acer, Acer America, Centon Electronics, Elpida Memory, International Products Sourcing Group, Kingston Technology, Nanya Technology, Peripheral Device and Product Systems, Powerchip Semiconductor, ProMOS Technologies, Ramaxel Technology, SMART Modular Technologies, and TwinMOS Technologies.
 
None of these companies is a Tessera licensee.
 
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 licensees.
 
The ITC is expected to decide whether to initiate an investigation 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 complaints, Tessera seeks remedies for infringement of four U.S. patents. Licensed companies include DRAM manufacturers Samsung, Hynix, Qimonda and Micron.
