What this shows Johnan's Innovation Score is 29.3/100 (30th 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 Johnan?

Each dot is one of Johnan’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). Johnan’s own 5.3 claims/patent is at or below the 11.2 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Johnan's grants concentrate

Johnan Manufacturing Inc. is a focused PatentsView assignee: 13 CPC subclasses with 78.9% of grants classified under E05F (Devices FOR Moving Wings Into Open OR Closed POSITION; Checks FOR WINGS; Wing Fittings NOT Otherwise Provided FOR, Concerned With THE Functioning OF THE Wing). Peak complete grant year is 2021 (6 grants) versus a trough of 1 in 2016. By volume, Johnan sits between Japan Cooperation Center Petroleum and Kaken Pharmaceutical Co., Ltd..

Johnan's three-year grant acceleration

Johnan Manufacturing Inc. shows 5 grants in 2022–2024 against only 11 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.
