What this shows Shanghai's Innovation Score is 47.2/100 (top 19% 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 17.2 claims/patent is ABOVE the 17.0 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 Research Institute OF Petrochemical Technology, Sinopec is a focused PatentsView assignee: 21 CPC subclasses with 64.5% of grants classified under C07C (Acyclic OR Carbocyclic Compounds). Peak complete grant year is 2021 (9 grants) versus a trough of 1 in 2022. By volume, Shanghai sits between Paris Presents Incorporated and Smart Wires Inc..

Shanghai's three-year grant acceleration

Shanghai Research Institute OF Petrochemical Technology, Sinopec shows 16 grants in 2022–2024 against only 19 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.
