Does more volume mean deeper claims for T-H?

Each dot is one of T-H’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). T-H’s own 13.7 claims/patent is ABOVE the 11.6 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where T-H's grants concentrate

T-H Marine Supplies, LLC is a focused PatentsView assignee: 21 CPC subclasses with 44.4% of grants classified under B63B (Ships OR Other Waterborne VESSELS; Equipment FOR Shipping). Peak complete grant year is 2018 (3 grants) versus a trough of 1 in 2015. By volume, T-H sits between Synvina C.V. and TAM International, Inc..

T-H's three-year grant acceleration

T-H Marine Supplies, LLC shows 5 grants in 2022–2024 against only 4 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.
