Although Gladwell would argue that Lisp, too, was as much an invention as anything done with it afterwards, insofar as the person who invented, say, CLOS was simply discovering it (in McCarthy's terms) before someone else did.
Probably a continuum from discovery to invention. I don't know CLOS, but it sounds like mostly an invention.

A. If I hadn't come up with it, someone else would have. Pure Lisp was a discovery, everything that has been done with it since has been an invention.
This brought back thoughts about Gladwell's recent essay which was posted here.
