What this shows Chenfeng's Innovation Score is 26.6/100 (21st 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 Chenfeng?

Each dot is one of Chenfeng’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). Chenfeng’s own 12.8 claims/patent is at or below the 16.7 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Chenfeng's grants concentrate

Chenfeng Optronics Corporation is a focused PatentsView assignee: 8 CPC subclasses with 66.7% of grants classified under G02B (Optical Elements, Systems OR Apparatus). Peak complete grant year is 2019 (3 grants) versus a trough of 1 in 2015. By volume, Chenfeng sits between CHD Holdings, LLC and China Automotive Systems, Inc..

Chenfeng's three-year grant acceleration

Chenfeng Optronics Corporation shows 1 grants in 2022–2024 against only 3 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.
