What this shows Keith's Innovation Score is 22.8/100 (11th 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 Keith?

Each dot is one of Keith’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). Keith’s own 6.7 claims/patent is at or below the 13.4 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Keith's grants concentrate

Keith Manufacturing Co. is a focused PatentsView assignee: 3 CPC subclasses with 92.9% of grants classified under B65G (Transport OR Storage Devices, e.g. Conveyors FOR Loading OR Tipping, Shop Conveyor Systems OR Pneumatic Tube Conveyors). Peak complete grant year is 2018 (5 grants) versus a trough of 1 in 2016. By volume, Keith sits between Kyocera Mita Corporation and Kiswe Mobile Inc..

Keith's three-year grant acceleration

Keith Manufacturing Co. shows 2 grants in 2022–2024 against only 4 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.
