Hmmm. I would have thought automobiles was very high IP. No reference, but don't VW or Audi hold more patents than any other company in the world or something?

Unilver, Sony etc submit 100s of 1000s of patents every year. Anyway, that aside, even if this chart is correct, a correlation does not imply any kind of causation. There many be any number of reasons why Food has more money spent on it (perhaps because we need food to survive and music consumption is purely discretionary?)
