Nanya opens the champers


Nanya Technology
said that the US International Trade Commission (ITC) has given it a clean bill of health and that is DRAM activities were all above board.

Tessera Technologies moaned to the FTC that chipmakers Elpida Memory, Nanya, Powerchip Semiconductor and ProMOS Technologies had violated its patents. The move follows a ruling by an administrative law judge found Tessera's patents US Patent No. 5663106, 6133627 and 5679977 weren't infringed in an action the company brought against memory-chip manufacturers.

The ITC said that three Tessera patents were valid, but Tessera's expert in the case "was insufficient to prove infringement by the respondents of two of the asserted patents."

There was some proof that the manufacturers had infringed the third patent in some of the products, but it seems that patent was exhausted so there was no violation of Section 337 of the Tariff Act of 1930.
