What this shows Crossfor's Innovation Score is 33.0/100 (43rd 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 Crossfor?

Each dot is one of Crossfor’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). Crossfor’s own 5.6 claims/patent is at or below the 14.9 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Crossfor's grants concentrate

Crossfor Co., Ltd. is a focused PatentsView assignee: 11 CPC subclasses with 53.3% of grants classified under A44C (Personal Adornments, e.g. JEWELLERY; Coins). Peak complete grant year is 2021 (4 grants) versus a trough of 1 in 2016. By volume, Crossfor sits between Corvid Technologies LLC and CustomArray, Inc..

Crossfor's three-year grant acceleration

Crossfor Co., Ltd. shows 5 grants in 2022–2024 against only 4 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.
