China Trademarks: Subclasses and Basic Numbers
Andrei Mincov's commentary on the original article
This is actually a great idea. Several classes of the Nice Classification contain entries that are totally different (for example, entertainment and education in class 41; a vast array of unrelated services in class 35, etc.) With 5 million trademarks filed in China every year, no wonder they wanted to subclassify products and services. In fact, this is probably the future of the world trademark system at some point.
