Patent Review And Re-issue Of United States Patent No. 7,531,709
Innovative Environmental Technology Inc. (IET) is pleased to announce that the patent challenge to UNITED STATES PATENT No. 7,531,709 ('709), a recognized, significant environmental technology has been successfully defended.
'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 U.S. Patent No. 7,531,709. Moreover, IET's patent is not tied into a specific mode of application, but offers examples using higher pressure injections.
IET's Perspective: "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 now, an acceptable, proven and widely used remedial approach for the treatment of chlorinated solvents."
Provectus' Perspective: "Provectus holds an exclusive license to IET's patent portfolio, including US Patent 7,531,709, with rights to sublicense the technology. As such we are committed to the defense and support of IET's patent rights," stated Dr. Jim Mueller President. Indeed, at Provectus we work with a myriad of environmental engineering firms, remedial construction firms, amendment and product suppliers to facilitate application of their own amendments or install our unique ISCO and antimethanogenic ISCR remedial products, all while respecting the rights of the '709 patent.

"We are very happy to have assisted IET/Provectus in the defense of the '709 Patent in the reexamination process," stated Douglas Ryder, Esq (Partner at Ryder, Lu, Mazzeo & Konieczny LLC – Colmar, PA). "The resulting Reexamination Certificate validates the technology captured in the '709 Patent and captures IET's continued commitment to defending their intellectual property. This should be a reminder to vendors and contractors who do not respect IET's '709 patent rights that they are subject to legal action for patent infringement. Moreover, technology end-users and their consultants should also be aware of their exposure to potential litigation through their use of unlicensed vendors and contractors,"
