What this shows Shanghai's Innovation Score is 33.8/100 (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 Shanghai?

Each dot is one of Shanghai’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). Shanghai’s own 21.9 claims/patent is ABOVE the 7.3 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Shanghai's grants concentrate

Shanghai National Engineering Research Center of Digital Television Co., Ltd. is a focused PatentsView assignee: 4 CPC subclasses with 100% of grants classified under H04L (Transmission OF Digital Information, e.g. Telegraphic Communication). Peak complete grant year is 2018 (2 grants) versus a trough of 1 in 2017. By volume, Shanghai sits between Service Ideas, Inc. and Shenzhen Gaodi Digital Co., Ltd..

Shanghai's three-year grant acceleration

Shanghai National Engineering Research Center of Digital Television Co., Ltd. shows 4 grants in 2022–2024 against only 6 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.
