What this shows Chan's Innovation Score is 42.2/100 (top 31% 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 Chan?

Each dot is one of Chan’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). Chan’s own 8.9 claims/patent is at or below the 13.3 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Chan's grants concentrate

Chan Li Machinery Co., Ltd. is a focused PatentsView assignee: 25 CPC subclasses with 53.8% of grants classified under B65H (Handling Thin OR Filamentary Material, e.g. Sheets, Webs, Cables). Peak complete grant year is 2015 (5 grants) versus a trough of 1 in 2019. By volume, Chan sits between Caterpillar Underground Mining Pty Ltd. and Chiral Photonics, Inc..

Chan's three-year grant acceleration

Chan Li Machinery Co., Ltd. shows 7 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.
