I ended up going a different route. I still have to hire a lawyer to do a prior art search to tell me if I'm violating any patents, if not, file one. I'm building a prototype of the idea and drawings now, but the damn prior art search is $1k-$2k just to tell you if it's already patented.

I found several similar patents but a few key parts in each are completely different from my plan, so I don't know if those different parts are enough to be considered an improvement to the process. But seeing what other people were granted patents for makes me think if it's not already taken that it could be patented. I was going to file a provisional claim as soon as I finish the prototype giving me a year to get the rest done.

Developing a great game is not an easy job and every developer wants to ensure that his efforts will be paid back.
There are different models of monetization but most common is Paid apps.
But there is a problem with pirates, keygens and so on...
As a team of software developers we decided to protect our stuff and has invented new app protection solution.
It is an online licensing service that prevents multiple copies of the software running at different Windows PCs.
If somebode is interested in such solution, just ask me for more detailed info. It is risk-free and we are not greedy (sometimes we support great projects for free)

Hate to be that guy, but are you sure something like this is even allowed by the advertisers?

I think it might fall under "inflating clicks artificially", since people would not anylonger click the ads because they are interested in the product, but just as a gameplay element.

From Admob FAQ:
Invalid clicks and impressions
Publishers may not click their own ads or use any means to inflate impressions and/or clicks artificially, including manual methods. Google treats invalid click activity very seriously, analyzing all clicks and impressions to determine whether they fit a pattern of use that might artificially drive up an advertiser's costs or a publisher's earnings. If we determine that an AdMob account might pose a risk to our advertisers, we may disable that account to protect our advertisers' interests.
