What this shows West's Innovation Score is 29.6/100 (31st 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 West?

Each dot is one of West’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). West’s own 9.9 claims/patent is at or below the 12.8 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where West's grants concentrate

West Coast Chain MFG. Co. is a focused PatentsView assignee: 15 CPC subclasses with 42.9% of grants classified under A45F (Travelling OR Camp EQUIPMENT: Sacks OR Packs Carried ON THE Body). Peak complete grant year is 2020 (4 grants) versus a trough of 1 in 2016. By volume, West sits between WD Racing OY and Woco Industrietechnik GmbH.

West's three-year grant acceleration

West Coast Chain MFG. Co. shows 1 grants in 2022–2024 against only 10 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.
