A Full Utility Patent Application costs a lot of money, why do it instead of a Provisional Patent Application (PPA)?
I know it seems like a lot of money at first, but, to frame the context more accurately, like any decision, it is all about assessing the opportunity -vs.- cost. On the opportunity side of the equation, if the opportunity seems to be relatively significant and there is some positive feedback from industry players (e.g., professionals, companies, academia, executives, etc.), then a less quality Patent Application (e.g., a do-it-yourself PPA) may risk losing a valuable deal if a big player deems the application as legally insufficient to warrant their investment or licensing. Another significant risk is that the weaker PPA might very well have technical and legal gaps in the disclosure that would allow would-be-copiers or licensees to more easily design around your patent, thereby losing all or part of your potential revenue stream.
