Have to be careful using this defence if what I have read becomes true.
I have read that the US patent department wants to change the rules to
who files first gets the patent. This could supersede prior art.
"Prior art" doesn't mean already patented. It means that if it can be
demonstrated that something has already been developed, you can't patent
it. For example, I don't know if anyone has patented the wheel, but
there is centuries of prior art.
