Does more volume mean deeper claims for Perkins?

Each dot is one of Perkins’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). Perkins’s own 17.8 claims/patent is ABOVE the 16.4 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Perkins's grants concentrate

Perkins Manufacturing Co. is a focused PatentsView assignee: 2 CPC subclasses with 100% of grants classified under B65F (Gathering OR Removal OF Domestic OR Like Refuse). Peak complete grant year is 2022 (2 grants) versus a trough of 1 in 2019. By volume, Perkins sits between Perceptia IP Pty Ltd and Pernix Ireland Pain Limited.

Perkins's three-year grant acceleration

Perkins Manufacturing Co. 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.
