Prior art: double clicking the application bar with _ O X on it for a web browser. Double tap is as old as the GUI.

Actually, double-click was invented at Apple in 1980 or 1981, some ten years after the WIMP paradigm was invented at Xerox, and 18 years after Ivan Sutherland invented a sort of graphical user interface for Sketchpad, which Alan Kay credits as "the invention of the GUI".

  That doesn't mean that Apple deserves a patent for every double-finger-twitch action in perpetuity, or that double-click doesn't logically follow from the reduction in mouse button count.

Lots of things "logically follow", but only a few make sense. Figuring that out seems to actually be fairly difficult as the state of the art shows.
