Zentek Ltd. (“Zentek” or the “Company”) (Nasdaq: ZTEK; TSX-V: ZEN), a graphene technology development and commercialization company, has filed patent applications for ZenGUARD™ in 47 countries.
The examiner for the Patent Cooperation Treaty, the international patent law treaty, that reviewed the ZenGUARD™ patent application opined that it met all 3 requirements to be granted a patent: novelty, an inventive step and industrial applicability. The Company has also been granted a patent for ZenGUARD™ by the Canadian Intellectual Property Office, as previously announced on December 7th, 2022. Examiners in other jurisdictions will use these actions as a basis for their own examinations and granting of patents in their respective countries.
The patented ZenGUARD™ antimicrobial technology platform has demonstrated it is a powerful solution for deactivating pathogens and increasing bacterial and viral filtration efficiency of both surgical masks and HVAC filters.
Based on the above information, the Company has decided to file patents in 47 new jurisdictions, including the United States, Europe, India and others and expects to be successful in all of them. The patent covers the chemical formula for ZenGUARD™, a fabrication method along with its application to various substrates, including surgical mask material, other personal protective equipment (PPE) and heating, ventilation, and air conditioning (HVAC) filters.
“We expect our patented ZenGUARD™ antimicrobial platform can provide numerous opportunities to give our business partners a competitive advantage in their respective markets, which we believe will make it a cornerstone for Zentek,” commented Greg Fenton, CEO of Zentek. He continued, “Importantly, this demonstrates our ability to move from a concept in the lab to a patent-protected technology platform that we hope to commercialize in numerous ways with several partners – all with the aim of making their products better, safer, and greener. We expect to follow a similar path for our other nanotechnologies, including ZenARMOR™, our patent-pending corrosion technology, and others.”
