Harness Dickey Upholds All Claims of Hotly Contested Patent

National Intellectual Property Firm Successfully Defends Innovative Fire Sprinkler Invention from the “Patent Killing Field”

Harness Dickey is pleased to announce that a team of attorneys in its Metro St. Louis office has successfully defended all claims of a client’s patent in an Inter Partes Review proceeding held within the United States Patent and Trademark Office.  Attorneys Michael Thomas, Bryan Wheelock and Joel Samuels secured an all-out victory before a board where, statistically, 81% of proceedings invalidate at least one patent claim, earning IPR proceedings the reputation of a “Patent Killing Field.”

The client, St. Louis-based Engineered Corrosion Solutions, LLC, owns U.S. Patent 9,144,700, which is directed to a dry pipe fire sprinkler system having a nitrogen generator for supplying pressure maintenance gas and a vent to eliminate oxygen to reduce corrosion.  This innovative technology was challenged on the grounds of obviousness by not one but two competitors, South-Tek Systems, LLC and Potter Electric Signal Co., LLC.  By upholding the patent’s claims, Harness Dickey was able to safeguard ECS’s intellectual property and maintain its commercial advantage in the fire sprinkler industry.

“We are very pleased with the outcome of the IPR review,” said Jeff Kochelek, CEO of Engineered Corrosion Solutions.  “In finding that Petitioners failed to establish any claims of the patent are unpatentable for obviousness, the USPTO’s decision confirms the strength and significant value of ECS’s patent.”

“Harness Dickey is proud to share in this victory with ECS,” said Michael Thomas. “This win underscores the merits of ECS’s technology as well as the hard work and expertise of our attorneys and staff.”

The patented system and other ECS technologies are used by clients around the country, including mission critical manufacturers and data centers, major retailers, sports stadiums, hotels, offices and airports.
