Yep. I filed through through WIPO for worldwide priority. Eventually my finances stretched as far as obtaining an Australian patent and a US patent. EU was going to cost tens of thousands for low probability. Chinese patent would've cost another 10k at least and it would be a gamble on the future state of IP enforcement there. There will be more expenses. $50k was the get as far as the US patent. I've spent another $3k since then on costs arising from other paperwork around it.
