What this shows Hampton's Innovation Score is 43.9/100 (top 27% 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 Hampton?

Each dot is one of Hampton’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). Hampton’s own 11.0 claims/patent is at or below the 16.5 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Hampton's grants concentrate

Hampton Products International Corporation is a focused PatentsView assignee: 27 CPC subclasses with 22.9% of grants classified under E05B (LOCKS; Accessories THEREFOR; Handcuffs). Peak complete grant year is 2018 (10 grants) versus a trough of 1 in 2023. By volume, Hampton sits between GW Research Limited and Innophase, Inc..

Hampton's three-year grant acceleration

Hampton Products International Corporation shows 9 grants in 2022–2024 against only 11 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.
