What this shows Maruyama's Innovation Score is 25.9/100 (19th 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 Maruyama?

Each dot is one of Maruyama’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). Maruyama’s own 6.1 claims/patent is at or below the 12.9 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Maruyama's grants concentrate

Maruyama MFG. Co., Inc. is a focused PatentsView assignee: 10 CPC subclasses with 16.7% of grants classified under F02M (Supplying Combustion Engines IN General With Combustible Mixtures OR Constituents Thereof). Peak complete grant year is 2018 (4 grants) versus a trough of 1 in 2015. By volume, Maruyama sits between Marklogic Corporation and Medical Microinstruments, Inc..

Maruyama's three-year grant acceleration

Maruyama MFG. Co., Inc. shows 1 grants in 2022–2024 against only 3 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.
