What this shows Shanghai's Innovation Score is 48.0/100 (top 17% 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 13.6 claims/patent is ABOVE the 8.1 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 Slamtec Co., Ltd. is a focused PatentsView assignee: 12 CPC subclasses with 75% of grants classified under G05D (Systems FOR Controlling OR Regulating Non-electric Variables). Peak complete grant year is 2022 (5 grants) versus a trough of 1 in 2020. By volume, Shanghai sits between Shanghai Oceania International Co., Ltd. and Shanghai Vanchip Technologies Co., Ltd..
Shanghai's three-year grant acceleration
Shanghai Slamtec Co., Ltd. shows 6 grants in 2022–2024 against only 2 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.
