Thermal Shipping Solutions (TSS) Prevails as the Exclusive Patent Owner of Its PET Insulated Liner Technology
NOVATO, Calif., May 21, 2025 /PRNewswire/ -- Thermal Shipping Solutions (TSS) holds the only relevant patent for its recyclable PET insulated box liner technology used in its popular Renewliner product, recognized as "The Most Sustainable, Temperature-Sensitive Product in the U.S."
This comes after Magistrate Judge Laurel Beeler of the United States District Court for the Northern District of California denied Cellulose Material Solutions' (CMS) request to reconsider her previous ruling that invalidated CMS's patent claims (U.S. Patent No. 11,078,007) against PET insulation technology used in its InfinityCore box liner. The judge rejected CMS's legal assertion, reaffirming that indeed TSS's product was offered for sale prior to CMS's patent claim.
"Humbly, we've always known what the court's recent decision validates — that our PET product innovation was exclusively ours in composition, design, and functionality. We worked tirelessly in developing and protecting Renewliner, which has become the gold standard in cold chain packaging integrity. We're proud of the product invention, so we're going to protect it," said Max Cardinale, Chief Executive Officer of TSS.
As the dominant patent owner for high-performance recyclable PET thermal liners, TSS's seminal patent, U.S. Patent No. 11,691,402, covers PET packaging insulation that keeps temperature-sensitive products like food, pharmaceuticals, and other perishables cold, preventing heat transfer, while maintaining a stable environment that is thermally safe, temperature secure, and earth sustainable. The recent ruling is not only a legal victory, but solidifies the company's leadership in the marketplace, further strengthening its ability to invest in optimized technologies, improving efficiency, sustainability, and reliability for its customers' shipped products.
As a U.S. leader in providing sustainable and effective cold chain solutions, the company comes from a long legacy of thermal product innovations, including, introducing the industry's original self-expanding, insulative protector mailer, and pioneering cold chain's first recyclable insulated shipping system.
"Look, we don't just solve problems. We engineer every brand product as the best possible solution. Products just don't get better on their own, better solutions make better products, and this is what we introduced with Renewliner," stated Sal Cardinale, Founder & President of TSS.
Inspired by their "Be Better" philosophy TSS uniquely employs Thermalists™, a powerhouse of accredited industry experts in thermal engineering and thermodynamics, who test, validate, and package-proof, every product using real world rigor and simulated climatic environments.
