Does more volume mean deeper claims for Dadco?

Each dot is one of Dadco’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). Dadco’s own 17.4 claims/patent is ABOVE the 13.7 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Dadco's grants concentrate

Dadco, Inc. is a focused PatentsView assignee: 12 CPC subclasses with 73.3% of grants classified under F16F (SPRINGS; SHOCK-ABSORBERS; Means FOR Damping Vibration). Peak complete grant year is 2024 (4 grants) versus a trough of 1 in 2017. By volume, Dadco sits between Cubist Pharmaceuticals LLC and DCG Systems, Inc..

Dadco's three-year grant acceleration

Dadco, Inc. shows 5 grants in 2022–2024 against only 3 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.
