What this shows Chance's Innovation Score is 41.1/100 (top 34% 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 Chance?

Each dot is one of Chance’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). Chance’s own 14.1 claims/patent is ABOVE the 11.3 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Chance's grants concentrate

Chance Line Industrial Co., Ltd. is a focused PatentsView assignee: 19 CPC subclasses with 42.9% of grants classified under G09F (DISPLAYING; ADVERTISING; SIGNS; Labels OR NAME-PLATES; Seals). Peak complete grant year is 2021 (2 grants) versus a trough of 1 in 2024. By volume, Chance sits between CG RAIL—CHINESISCH-DEUTSCHES Forschungs- UND Entwicklungszentrum FÜR Bahn- UND Verkehrstechnik Dresden GMBH and CHD Bioscience, Inc..

Chance's three-year grant acceleration

Chance Line Industrial Co., Ltd. shows 3 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.
