Does more volume mean deeper claims for Cadwell?

Each dot is one of Cadwell’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). Cadwell’s own 19.5 claims/patent is ABOVE the 14.3 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Cadwell's grants concentrate

Cadwell Laboratories, Inc. is a focused PatentsView assignee: 5 CPC subclasses with 82.6% of grants classified under A61B (DIAGNOSIS; SURGERY; Identification). Peak complete grant year is 2021 (5 grants) versus a trough of 1 in 2016. By volume, Cadwell sits between Cranial Technologies, Inc. and Chemische Fabrik Budenheim KG.

Cadwell's three-year grant acceleration

Cadwell Laboratories, Inc. shows 9 grants in 2022–2024 against only 10 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.
