Comment No one needs a motivation to invent (Score 1) 234
That would make sense if there was a shred of evidence that people only invent things because they hope to patent them. Say maybe if the world were full of saying like "IP protection is the mother of invention" or "invent a better mouse trap and the world will grant you exclusive use of the idea for a limited time."
Or suppose we had clear evidence that primitive people lived lives little different than those of other animals until some freak accident created the first intellectual property laws, triggering the taming of fire, agriculture, and so forth.
Of course, we don't see any of that. We don't live in that world and it takes a rather twisted view of human nature to swallow the notion that patents somehow cause invention.
On the other hand, all it takes to support the notion that patents were intended to cause disclosure of inventions is a little reading. For example, in the second paragraph of The Patent Act of 1790 we find the prerequisites for obtaining a patent and the reason for them spelt out. In the second full sentence of US patent law we are told that those seeking patents must:
[...] deliver to the Secretary of State a specification in writing, containing a description, accompanied with drafts or models, and explanations and models (if the nature of the invention or discovery will admit of a model) of the thing or things, by him or them invented or discovered, and described as aforesaid, in the said patents; which specification shall be so particular, and said models so exact, as not only to distinguish the invention or discovery from other things before known and used, but also to enable a workman or other person skilled in the art or manufacture, whereof it is a branch, or wherewith it may be nearest connected, to make, construct, or use the same, to the end that the public may have the full benefit thereof, after the expiration of the patent term;
If you want a patent on your gizmo, you have to fully disclose the details so anyone reasonably competent can make and use one after the patent expires.
That is what society gets out of it. The promotion of progress isn't about gulling people into inventing stuff (they were doing that already). It's about making sure that other people can copy those inventions, build on them, progress from them, rather than having the secret die with the inventor thus forcing everyone else to (as the saying goes) "reinvent the wheel".
