What this shows Miura's Innovation Score is 44.4/100 (top 26% 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 Miura's grants concentrate

Miura Co., Ltd. is a focused PatentsView assignee: 39 CPC subclasses with 35.1% of grants classified under F22B (Methods OF Steam GENERATION; Steam Boilers). Peak complete grant year is 2017 (9 grants) versus a trough of 2 in 2022. By volume, Miura sits between Luminar, LLC and Moldex-Metric, Inc..

Miura's three-year grant acceleration

Miura Co., Ltd. shows 5 grants in 2022–2024 against only 7 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.
