Patent Granted for Novel Anti-viral Seaweed Extract

Byotrol Plc (AIM: BYOT), the specialist infection prevention and control company, is pleased to report the approval today of a UK patent following its discovery of unique anti-viral properties of certain enhanced extracts of commonly available brown seaweed.

The award is a result of many years of research by Byotrol's technical team at its laboratories at Thornton Science Park, a University of Chester campus, and has been supported by the research scientists at the University of Liverpool led by Professor James Stewart, and by funding received from the Biotechnology and Biological Sciences Research Council (BBSRC) and Innovate UK.

The grant of the patent application gives Byotrol validated, valuable and protected intellectual property, to support the development of commercial relationships.

In the UK and Europe, seaweed extracts are not as yet approved as active materials for biocidal products, Byotrol's established area of expertise.  So, we are now actively exploring alternative applications in very sizeable markets such as over-the-counter (OTC) products for the prophylactic treatment of viral conditions including colds, flu, coronaviruses and cold sores.

Byotrol Plc's Chairman, Dr Trevor Francis, comments:

"We are delighted to have secured the first patent for our seaweed-based anti-viral technologies.  It is another good indication of the quality of our technical capability, and it will most certainly help us as we intensify the search for commercial partners.   It also adds to our already significant level of intellectual property in antimicrobials.

"This patent further confirms Byotrol's commitment to developing and commercializing natural and sustainable antimicrobial actives."
