What this shows Janome's Innovation Score is 43.9/100 (top 27% 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 Janome?

Each dot is one of Janome’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). Janome’s own 6.6 claims/patent is at or below the 18.9 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Janome's grants concentrate

Janome Corporation is a focused PatentsView assignee: 6 CPC subclasses with 76% of grants classified under D05B (Sewing). Peak complete grant year is 2024 (10 grants) versus a trough of 5 in 2022. By volume, Janome sits between Inventprise, LLC and Jiangxi University of Science and Technology.

Janome's three-year grant acceleration

Janome Corporation shows 21 grants in 2022–2024 against only 0 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.
