"China is about to overtake Japan in patent applications"- that seems to me the part of an on going seismic shift in the dynamics between two fiercely competing nations.

Here is an extract from The Economist article:
"Patents are a crude but useful measure of innovation. The change shows that Chinese inventors are developing a stake in intellectual-property protection, which is welcome. And because national patents protect the technologies of foreign firms too, the trend reflects how global companies are ploughing into China as a market and a manufacturing base. Even Japanese firms have increased their patent filings in China but decreased them at home."
