What this shows Dalian's Innovation Score is 26.0/100 (19th 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 Dalian?

Each dot is one of Dalian’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). Dalian’s own 9.6 claims/patent is at or below the 13.2 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Dalian's grants concentrate

Dalian Rongkepower Co., Ltd is a focused PatentsView assignee: 6 CPC subclasses with 100% 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 2021 (3 grants) versus a trough of 1 in 2016. By volume, Dalian sits between Dai-ichi High Frequency Co., Ltd. and DB Equipment AS.

Dalian's three-year grant acceleration

Dalian Rongkepower Co., Ltd shows 3 grants in 2022–2024 against only 6 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.
