US Patent 7,531,709 Validated in Reexamination
IET/Provectus Pleased to Announce ISCR Technology Validated During Reexamination - UNITED STATES PATENT No. 7,531,709
'709 Patent Overview:
Simply put, IET's technology captured in the '709 Patent consists of combining an organic hydrogen donor (e.g., oil, emulsified oil, lecithin, emulsified lecithin, fibrous organic matter / vegetable matter, sugars, et cetera) with zero valent metal (e.g., ZVI) for remediation of soil, sediment or groundwater. Therefore, any process that removes halogenated organic contaminants from groundwater that employs an organic hydrogen donor plus ZVI (or other zero valent metal) of any shape and size, often referred to as In Situ Chemical Reduction (ISCR), is covered by the '709 Patent. Moreover, IET's patent is not tied into a specific mode of application, but offers examples using higher pressure injections.
"IET developed and demonstrated the technology captured in US Patent 7,531,709 over 15 years ago as evidenced by its January 6, 2003 priority date. It took many years for the technology to become an accepted and common remediation approach." stated Mr. Michael Scalzi, inventor for '709 and founder of IET. "This reexamination and reissue of '709 affirms the validity and ownership of the technology through March 2025. I appreciate the wide-ranging support received from many industrial professionals who helped us present a technically defensible, convincing argument in support and recognition of the ownership of our patent. '709 is a proven and widely used remedial approach for the treatment of chlorinated solvents."
"Provectus holds an exclusive license to IET's patent portfolio, including US Patent 7,531,709, with rights to sublicense the technology.
