What this shows Lewco's Innovation Score is 24.1/100 (14th 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 Lewco?

Each dot is one of Lewco’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). Lewco’s own 15.2 claims/patent is ABOVE the 13.8 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Lewco's grants concentrate

Lewco, Inc. is a focused PatentsView assignee: 2 CPC subclasses with 91.7% 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 2019 (2 grants) versus a trough of 1 in 2016. By volume, Lewco sits between Laser Institute, Shandong Academy OF Sciences and Limo Patentverwaltung GmbH & Co. KG.

Lewco's three-year grant acceleration

Lewco, Inc. shows 1 grants in 2022–2024 against only 6 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.
