Hmm given all the intellectual theft and bootlegs and knock offs, I suspect the WTO complaints reflect a reality that US complaints mean something and Chinese complaints are a waste of time, thus there are fewer because nothing will be done.

You don't need to suspect or post rationalize. There are literal academic books and many papers analyzing Chinese WTO compliance record in Dispute Settlement Body (DSB), and several explicit compares and contrast US with China and EU, by western researchers. TL;DR: China isn't the devil. The latest one is literally called: China’s Implementation of the Rulings of the World Trade Organization (2019), but studies goes back a decade.
