What this shows Chengli's Innovation Score is 23.6/100 (12th 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 Chengli?

Each dot is one of Chengli’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). Chengli’s own 10.2 claims/patent is at or below the 14.6 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Chengli's grants concentrate

Chengli Li is a focused PatentsView assignee: 5 CPC subclasses with 100% of grants classified under H02H (Emergency Protective Circuit Arrangements). Peak complete grant year is 2017 (2 grants) versus a trough of 1 in 2023. By volume, Chengli sits between ChemLink Laboratories, LLC and Chicago Display Company.

Chengli's three-year grant acceleration

Chengli Li shows 1 grants in 2022–2024 against only 2 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.
