I have an idea for an invention but not sure if it is possible in reality. i.e. A lot of us might like the invention of cars which can fly like aeroplanes, but at present it is not possible.
So, my question is,how do I find out if my idea/invention can work in practice and how can I find out if that idea is already patented?
I have heard of the website espacenet which has a lot of info regarding patents, is this the best website to go to in order to find out if the idea’s already patented?
Thanks in advance for your responses.
