Product Systems Inc., Defends Its Single Wafer Megasonic Technology

Campbell, CA July 24, 2006 - Product Systems Inc. (“ProSys”) has responded to a patent infringement lawsuit filed by Akrion, Inc. (Case No. 2:06-CV-467 in the United States District Court for the Eastern District of Pennsylvania) and filed a countersuit for the infringement of a ProSys patent relating to Radial Uniform Megasonic Processing.

Megasonic processing has emerged as an increasingly important method of cleaning contamination and damage sensitive products. Radial Uniform Megasonic exposure helps improve the chemical and cleaning processes used while ensuring that every part of the rotating substrate is exposed to the same amount of acoustic energy. ProSys holds key patents in the area of Megasonic uniformity and Megasonic cleaning generally. In fact, ProSys has 12 US and international Megasonic-related patents of its own with 15 applications pending worldwide.

“ProSys has been designing, building, and patenting Megasonic Single Substrate processing solutions since the late1990’s” said Mark J. Beck, ProSys’ CEO and founder. “We do not copy, we innovate, and the market has responded to our ideas and products in a very positive way.”

“We have advanced Megasonic Processing in the areas of transducer design, acoustic uniformity, power control, and sonoluminescence metrology since our inception in 1996. Our products are based upon our considerable intellectual property, not the ideas or intellectual property of others. We will vigorously defend our intellectual property and our customers’ rights to purchase and use the ProSys products.” said Mr. Beck.
