More research on the patents - this stuff is hard to find, but, the sources are authoritative (Government websites) and the results are clear even to a lay person.
UK Patent Office - 6th November 2018

See section 6 and why the patent was rejected in the UK - similar to the AUS rejection.
Surely these rejections should have been in the prospectus?
A right of reply was requested by the Company and granted by IPO UK until 6th Feb 2019 - but nothing appears on record as a response (and it wouldnt take IPO UK a month and a half to update the details) - see the Telephone Record at > https://www.ipo.gov.uk/p-ipsum/Document/ApplicationNumber/GB1507531.0/a09cf769-f332-431c-81fa-4f0785f30aba/GB2521790-20181224-Report%20%20Telephone%20conversation.pdf and the lack of submission since > https://www.ipo.gov.uk/p-ipsum/Case/ApplicationNumber/GB1507531.0
I now no longer hold any stock as of today.
