What this shows Shima's Innovation Score is 34.3/100 (47th 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.

Where Shima's grants concentrate

Shima Seiki MFG., Ltd. is a focused PatentsView assignee: 18 CPC subclasses with 85.7% of grants classified under D04B (Knitting). Peak complete grant year is 2017 (9 grants) versus a trough of 1 in 2015. By volume, Shima sits between Sapproro Medical University and Sigma Enterprises, LLC.

Shima's three-year grant acceleration

Shima Seiki MFG., Ltd. shows 4 grants in 2022–2024 against only 8 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.
