Back in early college I wanted to toy with my location based app development skills. I created a Windows Phone game where Pokemon were scattered across a real world map in your area and you could walk/drive around and if you got close enough to said Pokemon you could catch it. Now of course I couldn't publish or do anything with the app as I didn't have the rights to Pokemon.
A few years later Google released essentially the same thing (better written of course) and it was a big hit. Now of course Pokemon Go was just released and is a worldwide sensation already, again doing essentially the same thing just much better.
Now again I know I have no rights to Pokemon but I was wondering, if I had tried and succeeded to patent something more general for my game back then such as "Geolocation based monster catching app for the phone using real world maps" insert lawyer talk, would I have some sort of IP case/royalties from these new games? Or would their specificity of owning Pokemon override my idea.
