What this shows BIG's Innovation Score is 25.9/100 (19th 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 BIG?

Each dot is one of BIG’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). BIG’s own 5.0 claims/patent is at or below the 14.4 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where BIG's grants concentrate

BIG Daishowa Co., Ltd. is a focused PatentsView assignee: 6 CPC subclasses with 87.5% of grants classified under B23Q (Details, Components, OR Accessories FOR Machine Tools, e.g. Arrangements FOR Copying OR Controlling ; Machine Tools IN General Characterised BY THE Construction OF Particular Details OR COMPONENTS; Co). Peak complete grant year is 2022 (2 grants) versus a trough of 1 in 2019. By volume, BIG sits between Better Walk, Inc. and Biodiscovery NEW Zealand Limited.

BIG's three-year grant acceleration

BIG Daishowa Co., Ltd. shows 3 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.
