What this shows Miyakoshi'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 Miyakoshi?

Each dot is one of Miyakoshi’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). Miyakoshi’s own 8.5 claims/patent is at or below the 14.3 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Miyakoshi's grants concentrate

Miyakoshi Printing Machinery Co., Ltd. is a focused PatentsView assignee: 19 CPC subclasses with 67.4% 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 2015 (13 grants) versus a trough of 1 in 2019. By volume, Miyakoshi sits between Leer Group and Mimosa Networks, Inc..

Miyakoshi's three-year grant acceleration

Miyakoshi Printing Machinery Co., Ltd. shows 1 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.
