Mr. Ivey, I agree with you on all points. If there were an easy answer, the answer would have probably been known long before either of us were born. Most inventors have more than one idea, and I believe the most difficult aspect for many resides in choosing which invention to devote full resources to for commercialization. For individual inventors with no experience, the deck is stacked agains them, since commercializing an intellectual asset is a multidisciplinary task and the individual with the required skill set is becoming scarcer by the day, owing to rapidly changing demographics.
The risk of losing everything varies directly with the extent that a given inventor does not have all of the Intelligence (I don't mean brains here) data when decision-making time approaches. I believe Mr. Auslander attempts to address this with his methods, to bring enamored inventors back to an earthly reality. The question of where one draws the line is the fleeting aspect, but in the end, most inventors will follow their heart if they believe in their invention enough. Following one's heart leads to a love affair, which sometimes ends up in heartbreak and other times leads to multiple offspring ! I always caution clients that the downside of filing for patent is that all of their money may be lost, including what they pay me, while at the same time the downside of not filing is the risk of seeing some other person with a patent on the same invention coming out in a year or two, because as you probably know, it is common for the same inveniton to be made by two different people at about the same point in time. If the other person makes $ 1MM, then the inventor will have to live with that. Which do they want to live with ? Losing a few 1000's of $, or seeing somone else come up with the same thing in the near future ? It is entirely up to the inventor as to what they choose to do.
Like I stated previously, the rewards go to those willing to take the risks !
best regards,
Chris
