ShieldMark and Mighty Line Prevail in Six-Year Federal Legal Battle Against Spota LLC and Clifford A. Lowe

CLEVELAND, OH, UNITED STATES, May 30, 2025 /EINPresswire.com/ -- After six years in the federal courts, ShieldMark, Inc., manufacturer of Mighty Line Floor Tape, is pleased to announce it has secured a significant victory in a patent dispute that was filed under Court Case No. 1:19-cv-00910-JRA and has now been dismissed with prejudice following multiple decisive rulings. The legal proceedings culminated in the Federal Circuit Court of Appeals on May 28, 2025, bringing finality to claims initially asserted by Clifford A. Lowe and Spota LLC (formerly InSite Solutions).

On August 23, 2022, the United States District Court for the Northern District of Ohio determined that Spota LLC and Mr. Lowe lacked standing due to an ongoing transfer of patent rights in U.S. Patent No. 10,214,664. The District Court also granted ShieldMark’s counterclaim, fully invalidating the challenged patent and ordering Mr. Lowe and Spota LLC to pay $213,765 in attorney fees and costs.

Furthermore, on March 24, 2025, the Federal Circuit Court of Appeals issued a decision reversing the standing determination but upholding the invalidation of U.S. Patent No. 10,214,664. The appellate court further affirmed the award of fees and additional interest in favor of ShieldMark, and dismissed the case with prejudice, bringing an end to all pending litigation.

This outcome reaffirms the innovation of Tom Goecke, founder of ShieldMark, who pioneered the beveled-edge floor marking tape design that has transformed warehouse and factory safety protocols. Since its introduction, Mighty Line Floor Tape has set a new standard for industrial-strength, precision-engineered solutions in high-traffic environments.

“We are proud that the courts have recognized our pioneering work and commitment to quality,” says Goecke. “This decision underscores the value of continuous innovation and reinforces our dedication to delivering the most reliable floor marking products in the industry.”
