What this shows Heathkit's Innovation Score is 46.3/100 (top 21% 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 Heathkit?

Each dot is one of Heathkit’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). Heathkit’s own 18.5 claims/patent is ABOVE the 11.5 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Heathkit's grants concentrate

Heathkit Company, Inc. is a focused PatentsView assignee: 13 CPC subclasses with 46.2% of grants classified under G01R (Measuring Electric VARIABLES; Measuring Magnetic Variables). Peak complete grant year is 2024 (6 grants) versus a trough of 1 in 2019. By volume, Heathkit sits between Harbin Medical University and Hizero Technologies Co., Ltd..

Heathkit's three-year grant acceleration

Heathkit Company, Inc. shows 8 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.
