Does more volume mean deeper claims for Carroll?

Each dot is one of Carroll’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). Carroll’s own 16.0 claims/patent is ABOVE the 11.0 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Carroll's grants concentrate

Carroll Hector, LLC is a focused PatentsView assignee: 5 CPC subclasses with 100% of grants classified under F03B (Machines OR Engines FOR Liquids). Peak complete grant year is 2021 (2 grants) versus a trough of 1 in 2020. By volume, Carroll sits between Cargo Cube Systems, LLC and Castle Biosciences, Inc..

Carroll's three-year grant acceleration

Carroll Hector, LLC shows 3 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.
