Being a patent holder myself and having various copyrights I have to say that the founding fathers were right in their action. The more I study these men the more profound I find their wisdom and understanding of human nature. Many people try to compare what they know today with them, as if they have greater understanding, when IMHO we are By Far dumbed down compared to their level of understanding regardless of our fancy devices, and atom bombs.
Contrary to popular belief, my patent does not stop you from building my machine, you simply cannot sell it here in the US. However just having my patent application may not give you enough detail to build the device on your own, thus creating the need to secure my services.
If it took me three years of constant effort and my own capital to create a device, I certainly believe anyone is entitled to At Least be reimbursed for such effort. But even with patents, ideas and inventions are STILL stolen, many inventors left broken.
To show you how little patents actually do help, just study Nikola Tesla. Nearly everything radio and electrical up to this very day are based on his patents, yet he died impoverished and despite his impact on mankind, few know of him.
I believe in patents for at least honoring the inventor, such as with Tesla being unknown. I believe there could be patent reform as it is now abused, such as large corporations buying up renewable ideas to maintain their Empire of Waste and Consumption. Devices so sophisticated that the average lab can't build for personal use and study anyway!
I believe in patents for AT LEAST allowing the inventor to break even!!
But I do believe in a cap on time limits, and I also believe in being able to build the device for personal use (one device) without infringement. Which is basically allowable today, it is personal know how that stops many people (labs/shops) in this vein.
IMHO patent reform MUST come AFTER government and business reform, because in a world as corrupt as today, EVERY inventor would be robbed, unknown, and penniless, regardless of the significance of his/her invention, if you disbanded patent law now.
If there was no protection for an inventor from these thieves and tyrants, then NO inventor would develop anything, and if they did they would hide it from everyone.
So YES, the founding fathers ARE encouraging the development of these things, albeit it could be slightly reformed.
Just My Opinion
