See Chao Ma, Xiaohong Yu & Haibo He, Data Analysis: Report on the Publication of Chinese Judicial Decisions on the Internet, China Law Review 12(4), 2016: 208. (Table 10 lists the ratios of the number of judicial documents of each province publicly available on CJO to the number of cases adjudicated in each province, ranging from 15.17% to 78.14%.)

So cherry-picked cases that range from 15-78% of the data set.

1.6k patent cases over multiple years seems -extremely- low to me. The USA has roughly 3-4x that per year. https://law.stanford.edu/wp-content/uploads/2016/07/Revised-...
