Kingston (ON), Canada – September 4th, 2025 – Cold Plasma Group (CPG), a pioneer in plasma-based sterilization technologies, is proud to announce that the United States Patent and Trademark Office has officially granted U.S. Patent No. 12,383,641, titled “Sterilization of Plant Material.” The patent was issued on August 12, 2025, following the company’s international filing on November 8, 2019, and U.S. filing on May 6, 2021.
This milestone marks the first granted patent in a global series of applications, with corresponding filings under review in Canada, the European Union, and other jurisdictions. The U.S. patent strengthens CPG’s leadership in cannabis microbial remediation and signals the beginning of a broader international expansion of its intellectual property portfolio.
Cannabis Sterilization: A Pressing Industry Need
Cannabis producers face strict microbial safety requirements, particularly under Good Manufacturing Practice (GMP) frameworks. Traditional sterilization methods, such as irradiation or chemical treatments, risk damaging product quality or leaving residues. CPG’s patented cold plasma process provides a powerful alternative by delivering:
Complete microbial remediation of cannabis flower, eliminating bacteria, fungi, and spores.
Non-destructive sterilization that preserves cannabinoids, terpenes, and other valuable compounds.
Chemical-free sustainability, aligning with regulatory and consumer demand for clean, natural products.
Global Strategic Impact
By securing its first patent in the U.S., CPG strengthens its position as a trusted partner for cannabis companies seeking EU-GMP compliance and access to international export markets. The pending patents in Canada and the EU will further establish CPG’s global IP footprint, ensuring long-term protection and competitive advantage.
“The sterilization of cannabis is one of the most pressing challenges for licensed producers, and our patented plasma solution provides a clean, effective, and non-thermal method to meet the highest quality standards,” said Dr. Florina Truica, CTO and Co-Founder of Cold Plasma Group. “This U.S. patent not only validates our innovation, but also opens the door to expanding cannabis exports into tightly regulated markets.”
Beyond Cannabis
Although cannabis sterilization is currently the primary focus, the patented process is also applicable to seeds, herbs, and agricultural materials, offering a versatile and sustainable platform for plant sterilization worldwide. The company is now expanding its focus to develop new business verticals to support various agri-sectors, a strategic move intended to diversify its product portfolio, acquire additional IP, tap into a growing bio-based market, and to support growth and green innovation.
