What this shows Shanghai's Innovation Score is 24.7/100 (15th percentile 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 16.7 claims/patent is ABOVE the 8.5 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 North Ocean Photonics Co., Ltd. is a focused PatentsView assignee: 1 CPC subclasses with 100% of grants classified under G02B (Optical Elements, Systems OR Apparatus). Peak complete grant year is 2021 (3 grants) versus a trough of 1 in 2022. By volume, Shanghai sits between Shanghai Benxu Precision Mold Co., Ltd. and Shanghai Xinshenpai Technology Co., Ltd..

Shanghai's three-year grant acceleration

Shanghai North Ocean Photonics Co., Ltd. shows 2 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.
