What this shows Shanghai's Innovation Score is 57.0/100 (top 6% 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 16.4 claims/patent is ABOVE the 13.0 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 Bright Power Semiconductor Co., Ltd. is a focused PatentsView assignee: 16 CPC subclasses with 59.5% of grants classified under H02M (Apparatus FOR Conversion Between AC AND AC, Between AC AND DC, OR Between DC AND DC, AND FOR USE With Mains OR Similar Power Supply SYSTEMS; Conversion OF DC OR AC Input Power Into Surge Output POWER;). Peak complete grant year is 2024 (12 grants) versus a trough of 1 in 2015. By volume, Shanghai sits between Samsung Techwin Co., Ltd. and Sigfox.

Shanghai's three-year grant acceleration

Shanghai Bright Power Semiconductor Co., Ltd. shows 29 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.
