What this shows Showa's Innovation Score is 34.4/100 (48th 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 11.2 claims/patent is at or below the 13.6 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 Aluminum CAN Corporation is a focused PatentsView assignee: 16 CPC subclasses with 54.2% of grants classified under B41J (TYPEWRITERS; Selective Printing Mechanisms, i.e. Mechanisms Printing Otherwise Than From A FORME; Correction OF Typographical Errors). Peak complete grant year is 2017 (6 grants) versus a trough of 1 in 2015. By volume, Showa sits between Shanghai Flexiv Robotics Technology Co., Ltd. and Somar Corporation.
Showa's three-year grant acceleration
Showa Aluminum CAN Corporation shows 4 grants in 2022–2024 against only 11 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.
