Regarding Patent vs. Brev.:
I think it had something do with the CPSC-mandated changes in mid-1977, since that forced some new tools on Tullio (and I'll bet p'ed him off royally). As the tools needed replacement, they went from "Patent" to "Brev." in the dies (although this was technically due more to an International Patent Law coverage issue I believe). Some were certainly done sooner than others, and I imagine it was a multi-year, prioritized-by-component program, and that for some components (depending on how expensive the new tooling was, and how many tools existed for that particular component), both styles were produced concurrently for some period of time.
Maybe Valentino Campagnolo could be more specific (maybe the records aren't thorough enough to show every tool's replacement schedule's details from 24 years ago too...)?
As for World logo hoods, I'd guess about 1978, but it was probably dependent on the demand and they "used up" the old-logo tooling after making the decision to change the logo. Some of these parts are still around as NOS today....
Short-reach (piccolo) brakes were on fairly early Raleigh Pros if I recall correctly (as were six-speeds) - maybe 1974? (they're in the 1975 #17a catalog).
Just my two cents,
