Does more volume mean deeper claims for AF?

Each dot is one of AF’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). AF’s own 14.5 claims/patent is ABOVE the 13.3 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where AF's grants concentrate

AF Chemicals, LLC is a focused PatentsView assignee: 9 CPC subclasses with 100% of grants classified under A61K (Preparations FOR Medical, Dental OR Toiletry Purposes). Peak complete grant year is 2021 (2 grants) versus a trough of 1 in 2016. By volume, AF sits between Adienne Pharma &biotech SA and Agiga Tech Inc..

AF's three-year grant acceleration

AF Chemicals, LLC shows 4 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.
