Does more volume mean deeper claims for Perfect?

Each dot is one of Perfect’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). Perfect’s own 56.8 claims/patent is ABOVE the 16.7 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Perfect's grants concentrate

Perfect DAY, Inc. is a focused PatentsView assignee: 10 CPC subclasses with 100% of grants classified under C07K (Peptides). By volume, Perfect sits between Pellficure Pharmaceuticals, Inc. and Perimeter Technologies, Inc..

Perfect's three-year grant acceleration

Perfect DAY, Inc. shows 2 grants in 2022–2024 against only 2 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.
