"Presently, we have 65 patents either in force, or pending, in major global regions around the world, and this is very significant as we advance PRP towards human trials."
"We continue to fund research programs with our university partners, and plan to file additional patent applications in the future," said Dr Julian Kenyon, Propanc’s Chief Scientific Officer. "Intellectual property lies at the heart of any early stage Biotech company and we look forward to expanding our portfolio covering further aspects of our invention related to PRP, especially as we advance further down the clinical development pathway."
