What this shows Nanjing's Innovation Score is 43.7/100 (top 27% 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 Nanjing?

Each dot is one of Nanjing’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). Nanjing’s own 5.6 claims/patent is at or below the 8.0 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Nanjing's grants concentrate

Nanjing Haohui HI Tech Co., Ltd. is a focused PatentsView assignee: 16 CPC subclasses with 100% of grants classified under Y02E (Reduction OF Greenhouse GAS [GHG] Emissions, Related TO Energy Generation, Transmission OR Distribution). By volume, Nanjing sits between Nammu21, Inc. and Nano Hesgarsazan Salamat Arya Ncubation Center FOR Medical Equipment AND Devices.

Nanjing's three-year grant acceleration

Nanjing Haohui HI Tech Co., Ltd. shows 4 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.
