ITC Judge Rules in Favor of AnalogicTech in Patent Infringement Case

Sunnyvale, CA – May 22, 2007 – Advanced Analogic Technologies Incorporated (AnalogicTech) (Nasdaq: AATI), a developer of power management semiconductors for mobile consumer electronic devices, today announced that it has prevailed in a case before the United States International Trade Commission (ITC) that was initiated by Linear Technology Corporation (Nasdaq: LLTC) (Linear). On May 22, 2007, Administrative Law Judge Sidney Harris of the ITC issued his Initial Determination, finding all asserted claims of Linear’s U.S. Patent Nos. 6,411,531 and 6,580,258 were either non-infringed or invalid. Based on this finding, Judge Harris ruled that none of AnalogicTech’s charge pump or switching regulator products should be subject to an exclusion order under Section 337 of the Tariff Act.

“We are very gratified that Judge Harris ruled in AnalogicTech’s favor on both the charge pump and switching regulator patents,” stated Richard K. Williams, President, CTO and CEO of AnalogicTech. “This ruling is a tremendous validation of our technology position and underscores our belief in and respect for intellectual property. We believe our victory in this case demonstrates that young companies can successfully compete and defend their intellectual property against industry giants.”

Following normal procedure, the Initial Determination will now be considered by the full ITC. The Final Determination is expected to be issued by September 22, 2007 and AnalogicTech anticipates Judge Harris’s findings will be confirmed at that time.

AnalogicTech is a recognized leader in specialized power management semiconductors and believes in promoting ingenuity through fair competition, as well as the protection of intellectual property.
