Does more volume mean deeper claims for Canfield?

Each dot is one of Canfield’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). Canfield’s own 24.2 claims/patent is ABOVE the 12.5 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Canfield's grants concentrate

Canfield Scientific, Incorporated is a focused PatentsView assignee: 12 CPC subclasses with 65% of grants classified under A61B (DIAGNOSIS; SURGERY; Identification). Peak complete grant year is 2020 (6 grants) versus a trough of 1 in 2019. By volume, Canfield sits between Cablofil, Inc. and Carrier Japan Corporation.

Canfield's three-year grant acceleration

Canfield Scientific, Incorporated shows 4 grants in 2022–2024 against only 9 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.
