Do you mean the man or the Company?
In the case of the Company, one thing that comes to mind is the anti-skid brake for the B-47. The design was then licensed to Hydro-Aire for production.
Citing this example avoids all the nasty arguments about who invented the swept wing, the podded jet engine etc. While Boeing did not necessarily invent these types of items, they did exploit them sooner and more effectively than their competition.
Innovation often means effective integration, something Boeing now says is its primary strength, ie large scale systems integration.
