What this shows West's Innovation Score is 34.3/100 (47th 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 38.5 claims/patent is ABOVE the 16.4 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where West's grants concentrate

West Virginia University Research Corporation is a focused PatentsView assignee: 7 CPC subclasses with 100% of grants classified under C01B (Non-metallic ELEMENTS; Compounds THEREOF; ; Metalloids OR Compounds Thereof NOT Covered BY Subclass C01c). Peak complete grant year is 2018 (3 grants) versus a trough of 1 in 2020. By volume, West sits between Wavin B.V. and Winview IP Holdings, LLC.

West's three-year grant acceleration

West Virginia University Research Corporation shows 1 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.
