What this shows F.r.'s Innovation Score is 30.4/100 (34th 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 F.r.?

Each dot is one of F.r.’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). F.r.’s own 14.8 claims/patent is ABOVE the 11.7 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where F.r.'s grants concentrate

F.R. Drake Company is a focused PatentsView assignee: 6 CPC subclasses with 86.7% 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 2020 (4 grants) versus a trough of 1 in 2018. By volume, F.r. sits between Excel Cell Electronics Co., Ltd. and Fico Triad, S.A..

F.r.'s three-year grant acceleration

F.R. Drake Company shows 4 grants in 2022–2024 against only 8 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.
