What this shows Hewitt's Innovation Score is 25.0/100 (16th percentile of the PatentsView-derived corpus). The chart places that score against the nearest Innovation Score peers plus corpus poles, not a reprint of the volume ranking.

Does more volume mean deeper claims for Hewitt?

Each dot is one of Hewitt’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). Hewitt’s own 14.4 claims/patent is ABOVE the 12.4 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Hewitt's grants concentrate

Hewitt Machine & Mfg. Inc. is a focused PatentsView assignee: 5 CPC subclasses with 80% of grants classified under B63C (Launching, Hauling-out, OR Dry-docking OF VESSELS; Life-saving IN WATER; Equipment FOR Dwelling OR Working Under WATER; Means FOR Salvaging OR Searching FOR Underwater Objects). Peak complete grant year is 2020 (2 grants) versus a trough of 1 in 2018. By volume, Hewitt sits between Herdstar, LLC and Hi-Tech Solutions Ltd..

Hewitt's three-year grant acceleration

Hewitt Machine & Mfg. Inc. shows 1 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.
