What this shows AC's Innovation Score is 45.7/100 (top 23% 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 AC?

Each dot is one of AC’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). AC’s own 24.9 claims/patent is ABOVE the 12.7 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where AC's grants concentrate

AC Immune SA is a focused PatentsView assignee: 9 CPC subclasses with 95.8% of grants classified under A61K (Preparations FOR Medical, Dental OR Toiletry Purposes). Peak complete grant year is 2020 (8 grants) versus a trough of 1 in 2021. By volume, AC sits between Yamazaki Mazak Corporation and Alector LLC.

AC's three-year grant acceleration

AC Immune SA shows 12 grants in 2022–2024 against only 12 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.
