Russian Excimer Patents Before 1-31-2005
2001 Device for ultraviolet inactivation of microorganisms – inventors E.A Sosnin L.V Lavrentiev , Victor F Tarasenko
The invention relates to ultraviolet inactivation of microorganisms. The device contains a flask made of a dielectric, transparent at a working wavelength, containing a mixture of gases, electrodes forming an internal discharge gap, a generator connected to both electrodes, the electrodes are tightly installed on the outer surface of the flask, the working medium contains an inert gas and halogen. The device operates at voltages up to 10 kV with a certain ratio of parameters. EFFECT: invention provides ultraviolet irradiation at a wavelength effective for inactivation (or a set of wavelengths), increasing the reliability and safety of the sterilization process for the operator.
“the discharge is associated with the structure of the terms of the working molecules formed by them (in the examples described, these are the KrCl* and XeBr* molecules). “

Ushio was the first to patent the 222nm excimer technology in the USA. These Ushio patents in the USA expired free-related, making them no longer enforceable several years before the USPTO was tricked into issuing new patents on old technology disclosed in several expired US patents!
Japan, South Korea, Taiwan, and USA Patents issued before 1-31-2005 Invalidates any US patent claim to 222nm excimer lamps!
