Does more volume mean deeper claims for Musashi?
Each dot is one of Musashi’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). Musashi’s own 9.9 claims/patent is at or below the 12.4 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.
Where Musashi's grants concentrate
Musashi Seimitsu Industry Co., Ltd. is a focused PatentsView assignee: 16 CPC subclasses with 89.1% of grants classified under F16H (Gearing). Peak complete grant year is 2016 (7 grants) versus a trough of 1 in 2015. By volume, Musashi sits between Mahle Filter Systems Japan Corporation and Plant 21 LLC.
Musashi's three-year grant acceleration
Musashi Seimitsu Industry Co., Ltd. shows 15 grants in 2022–2024 against only 14 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.
