Does more volume mean deeper claims for Corbett?

Each dot is one of Corbett’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). Corbett’s own 4.0 claims/patent is at or below the 19.8 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Corbett's grants concentrate

Corbett Lair Inc. is a focused PatentsView assignee: 6 CPC subclasses with 22.4% of grants classified under A61F (Filters Implantable Into Blood VESSELS; PROSTHESES; Devices Providing Patency TO, OR Preventing Collapsing OF, Tubular Structures OF THE Body, e.g. STENTS; Orthopaedic, Nursing OR Contraceptive Device). Peak complete grant year is 2016 (11 grants) versus a trough of 1 in 2021. By volume, Corbett sits between Cardinal CG Company and Dassault Systemes Americas Corp..

Corbett's three-year grant acceleration

Corbett Lair Inc. shows 1 grants in 2022–2024 against only 15 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.
