What this shows Marshall's Innovation Score is 47.8/100 (top 18% 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 Marshall?

Each dot is one of Marshall’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). Marshall’s own 16.0 claims/patent is ABOVE the 13.4 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Marshall's grants concentrate

Marshall University Research Corporation is a focused PatentsView assignee: 19 CPC subclasses with 54.5% of grants classified under A61K (Preparations FOR Medical, Dental OR Toiletry Purposes). Peak complete grant year is 2024 (5 grants) versus a trough of 1 in 2016. By volume, Marshall sits between Mindmaze Group SA and McNeil-PPC, Inc..

Marshall's three-year grant acceleration

Marshall University Research Corporation shows 9 grants in 2022–2024 against only 5 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.
