There`re big ideas and then there`re smaller ones. It is important to assess the size of the market before patenting an invention. Wise inventors address huge problems.
The current patent system allows an inventor at least a year to test out the market viability of his invention by using PPA. If he couldn`t market his gizmo during that period, he may as well not file PA to keep it a secret, taking the chance that another inventor may come up with same invention and apply for a patent.
There`s no simple answer about invention and invention-based business, but like Jesus said, know the cost of the project before doing it.
The art of patent drafting is learnable. Most patent examiners are engineers and attorneys. As an inventor and a decent pro se patent drafter, I have a huge advantage of speed, quality, and cost. Yet I`m very selective in what I apply for patent. i.e. only what I`m gonna commercialize. I have considered becoming a patent agent but opted for hi-tech business. It`s selling one`s time vs selling products worldwide.
