What this shows HFA's Innovation Score is 20.0/100 (6th 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 HFA?

Each dot is one of HFA’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). HFA’s own 1.5 claims/patent is at or below the 12.3 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where HFA's grants concentrate

HFA, Inc. is a focused PatentsView assignee: 3 CPC subclasses with 21.7% of grants classified under B21D (Working OR Processing OF Sheet Metal OR Metal Tubes, Rods OR Profiles Without Essentially Removing MATERIAL; Punching Metal). Peak complete grant year is 2021 (9 grants) versus a trough of 2 in 2019. By volume, HFA sits between Guangzhou Songxianjun Trading Co., Ltd. and Hoya Candeo Optronics Corporation.

HFA's three-year grant acceleration

HFA, Inc. shows 4 grants in 2022–2024 against only 13 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.
