What this shows Star's Innovation Score is 43.8/100 (top 27% 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 Star?

Each dot is one of Star’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). Star’s own 7.7 claims/patent is at or below the 11.2 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Star's grants concentrate

Star Micronics Co., Ltd. is a focused PatentsView assignee: 26 CPC subclasses with 46.7% of grants classified under B23B (TURNING; Boring). Peak complete grant year is 2019 (8 grants) versus a trough of 1 in 2021. By volume, Star sits between SCG Chemicals Co. Ltd and Sciosense B.V..

Star's three-year grant acceleration

Star Micronics Co., Ltd. shows 13 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.
