What this shows Shanghai's Innovation Score is 52.3/100 (top 10% 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 19.3 claims/patent is ABOVE the 10.9 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 Roye Electric Co., Ltd. is a focused PatentsView assignee: 10 CPC subclasses with 100% of grants classified under G01N (Investigating OR Analysing Materials BY Determining Their Chemical OR Physical Properties). By volume, Shanghai sits between SDS Biotech K.K. and Shenzhen Jingtai Technology Co., Ltd..

Shanghai's three-year grant acceleration

Shanghai Roye Electric Co., Ltd. shows 10 grants in 2022–2024 against only 0 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.
