What this shows Chongqing's Innovation Score is 54.3/100 (top 8% 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 Chongqing?

Each dot is one of Chongqing’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). Chongqing’s own 17.0 claims/patent is ABOVE the 14.3 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Chongqing's grants concentrate

Chongqing Jinkang Powertrain NEW Energy Co., Ltd. is a focused PatentsView assignee: 16 CPC subclasses with 76.5% of grants classified under H01M (Processes OR Means, e.g. Batteries, FOR THE Direct Conversion OF Chemical Energy Into Electrical Energy). Peak complete grant year is 2022 (14 grants) versus a trough of 1 in 2021. By volume, Chongqing sits between Cellcontrol, Inc. and Compugroup Medical SE.

Chongqing's three-year grant acceleration

Chongqing Jinkang Powertrain NEW Energy Co., Ltd. shows 16 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.
