What this shows Showa's Innovation Score is 31.5/100 (38th 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 Showa?

Each dot is one of Showa’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). Showa’s own 3.9 claims/patent is at or below the 15.9 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Showa's grants concentrate

Showa Glove Co. is a focused PatentsView assignee: 11 CPC subclasses with 65.7% of grants classified under A41D (OUTERWEAR; Protective GARMENTS; Accessories). Peak complete grant year is 2021 (6 grants) versus a trough of 1 in 2015. By volume, Showa sits between Sanofi Biotechnology and Subsea 7 Norway AS.

Showa's three-year grant acceleration

Showa Glove Co. shows 12 grants in 2022–2024 against only 16 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.
