What this shows HMS's Innovation Score is 24.4/100 (15th 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 HMS?

Each dot is one of HMS’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). HMS’s own 7.4 claims/patent is at or below the 12.0 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where HMS's grants concentrate

HMS MFG Co. is a focused PatentsView assignee: 6 CPC subclasses with 22.2% of grants classified under B62B (Hand-propelled Vehicles, e.g. Hand Carts OR PERAMBULATORS; Sledges). Peak complete grant year is 2019 (2 grants) versus a trough of 1 in 2015. By volume, HMS sits between Hitachi Automotive Systems Kyushu, Ltd. and Horton DO Brasil Tecnologia Offshore, Ltda..

HMS's three-year grant acceleration

HMS MFG Co. shows 2 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.
