What this shows Nanjing's Innovation Score is 41.6/100 (top 33% 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 9.8 claims/patent is at or below the 14.3 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 Easthouse Electrical Co., Ltd. is a focused PatentsView assignee: 19 CPC subclasses with 33.3% of grants classified under G07C (Time OR Attendance REGISTERS; Registering OR Indicating THE Working OF MACHINES; Generating Random NUMBERS; Voting OR Lottery APPARATUS; Arrangements, Systems OR Apparatus FOR Checking NOT Provided FO). Peak complete grant year is 2023 (7 grants) versus a trough of 1 in 2017. By volume, Nanjing sits between Nationwide Children's Hospital, Inc. and Nomadix, Inc..

Nanjing's three-year grant acceleration

Nanjing Easthouse Electrical Co., Ltd. shows 16 grants in 2022–2024 against only 13 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.
