Does more volume mean deeper claims for Tulsa?

Each dot is one of Tulsa’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). Tulsa’s own 12.9 claims/patent is at or below the 17.5 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Tulsa's grants concentrate

Tulsa Winch, Inc. is a focused PatentsView assignee: 10 CPC subclasses with 50% of grants classified under B66C (CRANES; Load-engaging Elements OR Devices FOR Cranes, Capstans, Winches, OR Tackles). Peak complete grant year is 2021 (2 grants) versus a trough of 1 in 2016. By volume, Tulsa sits between Trofimuk Institute of Petroleum Geology and Geophysics and Tyger Manufacturing LLC.

Tulsa's three-year grant acceleration

Tulsa Winch, Inc. 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.
