Patent Review And Re-issue Of United States Patent No. 7,531,709

PIPERSVILLE, Pa., July 23, 2018 /PRNewswire/ -- On August 18, 2017 an anonymous ex parte request for reexamination of claims 1-12 and 14-16 of Innovative Environmental Technologies, Inc. (IET – Pipersville, PA) US Patent 7,531,709 B2 was filed (It was determined that the request was filed by OnMaterials, LLC (www.onmaterials.com) who had a sublicense to the '709 Patent. Following a rigorous review by the U.S. Patent and Trademark Office (USPTO) that included consideration of extensive expert declarations, IET/Provectus are very pleased to announce that an Ex Parte Reexamination Certificate was issued on July 16, 2018.  The Reexamination Certificate validates the unique abiotic/biotic remediation methodology described in the '709 Patent and includes minor revisions to the claims that clarify the invention

'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.

Legal Perspective:

Requests for ex parte reexamination (www.uspto.gov/web/offices/pac/mpep/s2209.html) represents a procedure that enables the Patent Owner or third parties to request the USPTO reexamine an issued patent based on substantially new question of patentability (SNQ). Third party requests are often filed in an attempt to invalidate a competitor's patent and have it revoked.  If the request presents a SNQ, then the reexamination proceeds in a manner similar to regular examination procedures in patent applications. When the prosecution of a reexamination proceeding is finalized, a reexamination certificate is issued which indicates the status of all claims following the reexamination.  In the '709 Patent all of the claims were determined to be patentable including claims that were amended and new claims that were added.

"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," stated Ryder. It is inherently unfair to formal licensees such as Provectus and their sublicensees who respect the intellectual property rights of others and thus obtained a license for a fee to be at a cost disadvantage to those who disrespect and misappropriate patented technology.  As such, "We join IET/Provectus in their commitment to enforcing the value of their patents and we will continue to support their patent protection and litigation efforts," said Mr. Ryder.
