What this shows Shanghai's Innovation Score is 38.3/100 (top 41% 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 7.1 claims/patent is at or below the 13.1 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Shanghai's grants concentrate

Shanghai Sansi Electronic Engineering Co. Ltd. is a focused PatentsView assignee: 16 CPC subclasses with 61.9% of grants classified under F21V (Functional Features OR Details OF Lighting Devices OR Systems THEREOF; Structural Combinations OF Lighting Devices With Other Articles, NOT Otherwise Provided FOR). Peak complete grant year is 2023 (5 grants) versus a trough of 1 in 2015. By volume, Shanghai sits between Sea to Summit Pty Ltd and Silicon Line GmbH.

Shanghai's three-year grant acceleration

Shanghai Sansi Electronic Engineering Co. Ltd. shows 11 grants in 2022–2024 against only 8 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.
