Digital Property and opting it as career?

i would like your views on digital property specifically patents and opting it as career. turning your pet projects into prototypes and patenting them. selling or renting them for making money. I know about 97% of patents fails. most of them are pretty silly. and design patents are easily created. and yes plants patents do exists. but my question is in general. I have a background in CS so mostly my ideas will be IT based.
