Patent protection

It sounds like you are asking about trying to get IP coverage in the UK for the application you filed in Australia. Most countries allow a one year grace period to claim priority. So you would need to find out if you can still claim priority (within the year), and if you can, then hire an attorney in the UK (or EPO) etc., to file an application there for you. If you have passed the one year mark, then your Australian application would be considered a barring prior art.

Hope this helps!
