What this shows Shanghai's Innovation Score is 32.9/100 (43rd 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 10.4 claims/patent is ABOVE the 9.4 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 Nuclear Engineering Research & Design Institute Co., Ltd. is a focused PatentsView assignee: 11 CPC subclasses with 90% of grants classified under Y02E (Reduction OF Greenhouse GAS [GHG] Emissions, Related TO Energy Generation, Transmission OR Distribution). Peak complete grant year is 2020 (3 grants) versus a trough of 1 in 2016. By volume, Shanghai sits between Shanghai Air-paq Composite Material Co., Ltd. and Shenzhen Buddy Technology Development Co., Ltd..

Shanghai's three-year grant acceleration

Shanghai Nuclear Engineering Research & Design Institute Co., Ltd. shows 3 grants in 2022–2024 against only 3 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.
