To the guy claiming S Korea has more patents than the US, I did some research into WIPO's latest database (2007) to stop both of you from making non-sense claims and reveal the truth. So here we go, straight from the horse's mouth:

-South Korea had the world's largest filings per GDP, ahead of all countries.
-South Korea had the world's largest filings per R&D;, ahead of all countries.
-South Korea had the world's 2nd largest filings per million population, ahead of USA and Germany, UK and France.
-South Korea had the world's 3rd largest resident filings , ahead of EU and Germany, UK, France and Canada.
-South Korea had  the world's 4th largest total patent filings, ahead of EU, Germany, Canada, UK and France.

So I guess Lakshmix claim isn't completely wrong but Aerain is right in that the US has more total patents than S Korea. I think the sentence simply needs rephrasing, as you can see above.
