What this shows Junkosha's Innovation Score is 46.7/100 (top 20% 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 Junkosha?

Each dot is one of Junkosha’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). Junkosha’s own 10.9 claims/patent is at or below the 11.5 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Junkosha's grants concentrate

Junkosha Inc. is a focused PatentsView assignee: 28 CPC subclasses with 29.7% of grants classified under F16L (PIPES; Joints OR Fittings FOR PIPES; Supports FOR Pipes, Cables OR Protective TUBING; Means FOR Thermal Insulation IN General). Peak complete grant year is 2016 (5 grants) versus a trough of 1 in 2015. By volume, Junkosha sits between Infinitum Electric Inc. and KIP Prod P1 LP.

Junkosha's three-year grant acceleration

Junkosha Inc. shows 12 grants in 2022–2024 against only 9 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.
