What this shows Shanghai's Innovation Score is 45.8/100 (top 22% 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 10.5 claims/patent is at or below the 14.2 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 Highly Electrical Appliances Co., Ltd. is a focused PatentsView assignee: 13 CPC subclasses with 50% of grants classified under F04B (Positive-displacement Machines FOR LIQUIDS; Pumps). Peak complete grant year is 2022 (4 grants) versus a trough of 1 in 2021. By volume, Shanghai sits between Shang HAI PAN SHI TOU ZI Guan LI YOU Xian Gong SI and Shanghai Microport EP Medtech Co., Ltd..

Shanghai's three-year grant acceleration

Shanghai Highly Electrical Appliances Co., Ltd. shows 5 grants in 2022–2024 against only 1 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.
