Keywords: Patents

Positron Systems, Inc. (“Positron”), a provider of advanced nondestructive and material characterization testing, has been informed that the United States Patent and Trademark Office (“USPTO”) has issued a Notice of Allowance for a patent application entitled “Method for Photon Activation Positron Annihilation Analysis” filed by the Idaho National Laboratory. Upon receiving payment of $1,700 in fees, the USPTO will issue the patent on or before 6 October 2005. When issued, Positron will become the worldwide, exclusive licensee of the patent.

When issued, the patent will protect Positron's induced positron annihilation volumetric (IPA-V) technology. IPA-V assesses material damage up to four inches deep and has significant market applications for component inspections and health monitoring, remaining life assessment and inspection compliance in aerospace, power generation and other markets. States Board of Directors Chairman Steve Bolen: “The new patent represents a major advancement for the Company and greatly increases the value of our intellectual property portfolio.”

About Positron Systems' Induced Positron Annihilation (IPA) Technologies.

The IPA process involves penetrating materials with a photon beam generated by a small linear accelerator or other techniques to create positrons, which are attracted to nano-sized defects in the material. Eventually, the positrons collide with electrons in the material and are annihilated, releasing energy in the form of gamma rays. The gamma ray energy spectrum creates a distinct and readable signature of the defects or damage present in the material.

IPA can detect a wide variety of damage types in a wide variety of materials including metals, polymers, ceramics and composites. Because IPA examines materials at the atomic level, it can detect damage at its earliest stage, from initial manufacture through failure. The technology can detect damage in second-layer materials and may prove useful in determining the remaining useful life of a component.
