Wow, I was surprised to see that Apple has patents on those, especially the one on pull-down menus. Wasn't pull-down menus there in some old Xerox computer?

Pull-downs are entirely Apple's:

That's interesting, IIRC pull-downs were used in GEM and Amiga Workbench too...

The Apple Lisa was released in January 1983, GEM was first demoed in November 1984 (http://en.wikipedia.org/wiki/Graphical_Environment_Manager, http://en.wikipedia.org/wiki/COMDEX), and Amiga Workbench was released in july 1985 (http://en.wikipedia.org/wiki/Workbench_(AmigaOS), http://en.wikipedia.org/wiki/Amiga_1000)

I don't think anybody ever claimed parallel inventions here.

They both did, but came after Apples implement implementation in Lisa.
