What this shows China's Innovation Score is 33.6/100 (45th percentile of the PatentsView-derived corpus). The chart places that score against the nearest Innovation Score peers plus corpus poles, not a reprint of the volume ranking.
Does more volume mean deeper claims for China?
Each dot is one of China’s 8 nearest volume peers (same corpus rank neighbourhood as the chart above), placed by total granted patents (horizontal) against average claims per patent (vertical). China’s own 17.0 claims/patent is ABOVE the 13.4 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.
Where China's grants concentrate
China Iwncomm Co., Ltd. is a focused PatentsView assignee: 5 CPC subclasses with 97.5% of grants classified under H04L (Transmission OF Digital Information, e.g. Telegraphic Communication). Peak complete grant year is 2015 (9 grants) versus a trough of 1 in 2023. By volume, China sits between Belgravia Wood Limited and Cathay Biotech Inc..
China's three-year grant acceleration
China Iwncomm Co., Ltd. shows 4 grants in 2022–2024 against only 10 in 2019–2021. That prior window is too thin for a growth multiple (rename and spin-out assignees look artificially high when the baseline is near zero), so PlainPatent withholds a ranked acceleration claim here.
