Usually Apple does not invent anything, they design using what other people have invented.
Apple does not focus on research as much as in development. They put billions into factories that mass produce what has been already proven to work.
Multi touch for example was not invented by Apple, Apple bought a company that invented most of the technology and brought it into telephones.
They did not invented Gorilla glass or accelerometers or small hard drives(like in the old ipod). They approached inventors and offered using their technologies in the millions or tens of millions of units.
