What this shows Arbutus's Innovation Score is 48.1/100 (top 17% 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 Arbutus?

Each dot is one of Arbutus’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). Arbutus’s own 20.3 claims/patent is ABOVE the 14.6 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Arbutus's grants concentrate

Arbutus Biopharma Corporation is a focused PatentsView assignee: 15 CPC subclasses with 91.4% of grants classified under A61K (Preparations FOR Medical, Dental OR Toiletry Purposes). Peak complete grant year is 2017 (9 grants) versus a trough of 1 in 2016. By volume, Arbutus sits between uBiome, Inc. and Amphipod, Inc..

Arbutus's three-year grant acceleration

Arbutus Biopharma Corporation shows 22 grants in 2022–2024 against only 18 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.
