What this shows Whitestone's Innovation Score is 47.0/100 (top 19% 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 Whitestone?

Each dot is one of Whitestone’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). Whitestone’s own 7.5 claims/patent is at or below the 11.1 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Whitestone's grants concentrate

Whitestone Co., Ltd. is a focused PatentsView assignee: 13 CPC subclasses with 62.5% of grants classified under G06F (Electric Digital Data Processing). Peak complete grant year is 2022 (7 grants) versus a trough of 1 in 2018. By volume, Whitestone sits between Väderstad Holding AB and Wisilica Inc..

Whitestone's three-year grant acceleration

Whitestone Co., Ltd. shows 11 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.
