His was a valid request to ask that someone back up a claim.

Love your user name, btw. Niven fan.
You might be too young to know, but Korea went through a pretty horrible war in the 50s, not long after being really messed up during WW-II.
So, the same as with Japan and Germany, their slow rebuilding of industry often relied on copying the US for a long time. It takes a while for countries to recover from being bombed to nearly nothing.
Of course, we all know what happened later on in the 1980s, when Japanese technology and Germany engineering caught up and started eating American products for lunch. Yep, the USA started copying those other countries.
Korea, who is still technically at war, and always under nuclear threat from a nutcase close by, has to go through a similar healing and growing process just like any other, but it will take longer there.
I'd say they're getting pretty innovative, but yes in general I'd say that in that part of the world, locking down ideas to a single owner is not seen as a valuable concept. Such is life. Different cultures.
