What this shows 42maru's Innovation Score is 44.2/100 (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.

Does more volume mean deeper claims for 42maru?

Each dot is one of 42maru’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). 42maru’s own 10.5 claims/patent is at or below the 18.0 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where 42maru's grants concentrate

42Maru Inc. is a focused PatentsView assignee: 4 CPC subclasses with 95.5% of grants classified under G06F (Electric Digital Data Processing). Peak complete grant year is 2024 (7 grants) versus a trough of 1 in 2020. By volume, 42maru sits between ip.access Limited and Acsuper Technologies Inc..

42maru's three-year grant acceleration

42Maru Inc. shows 17 grants in 2022–2024 against only 1 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.
