BioVaxys Broadens Intellectual Property Portfolio Commercial Trademark Application Filed for CoviDTH(R) Diagnostic

Commercial trademark application FILED for CoviDTH® diagnostic cancer vaccine platform patent coverage expanded to NOW include over 12 tumor types

VANCOUVER, B.C.,BioVaxys Technology Corp. (CSE: BIOV) (FRA: 5LB) (OTC: BVAXF) ("BioVaxys" or "the Company"), the world leader in haptenized antigen vaccines for antiviral and cancer applications, announced today that it has filed with the United States Patent & Trademark Office ("USPTO") an intent-to-use application to register the mark CoviDTH®, it's novel disposable T-cell immune response diagnostic for SARS-CoV-2. 

BioVaxys President and CEO Kenneth Kovan commented "As we get closer to market, we needed to register a trademark that would be descriptive, memorable, and defendable.  CoviDTH® is an ideal mark as it combines the letters DTH, or delayed type hypersensitivity, the mechanism behind our T-cell immune response diagnostic, with Covid-19."

In another action that further builds their IP portfolio, BioVaxys broadened the patent coverage for its bihaptenized tumor antigen vaccine platform by filing an international patent application through the Patent Cooperation Treaty ("PCT") with additional claims for cervical cancer.  In addition to cervical and ovarian cancer, patent claims for BioVaxys' cancer vaccine platform align with their oncology vaccine development plans and include other gynecological cancer targets such as uterine, vaginal, vulvar, and endometrial cancers.  Other tumor targets of commercial interest covered by its patent applications include melanoma, lung cancer, renal cell carcinoma, pancreatic cancer, colorectal cancer, breast cancer, and leukemia. 

An International PCT Application, which is a patent treaty with more than 150 member countries, makes it possible to seek patent protection for an invention simultaneously in a large number of countries by filing a single "international" patent application instead of filing several separate national or regional patent applications.  In March 2021, BioVaxys entered the National Phase with its bihaptenized tumor antigen platform patent application to pursue expanded patent protection in the major pharmaceutical markets of US, European Union (including the UK and Turkey), Australia, Canada, China, India, Japan, Russia, Brazil, and South Korea. 

BioVaxys' pursuit of a cervical cancer vaccine patent claim is related to its partnership with Procare Health Iberia of Barcelona, Spain, which includes joint clinical development of BioVaxys' bihaptenized antigen vaccine platform for ovarian cancer, cervical cancer  and  Human Papilloma Virus ("HPV"), as well as the right of first refusal for marketing by BioVaxys in the United States of Procare Health's vaginal gel product, Papilocare™, the world's first and only product to prevent and treat HPV-dependent cervical lesions.
