What this shows Sub-zero's Innovation Score is 54.2/100 (top 8% 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 Sub-zero?

Each dot is one of Sub-zero’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). Sub-zero’s own 11.5 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 Sub-zero's grants concentrate

Sub-Zero Group, Inc. is a focused PatentsView assignee: 32 CPC subclasses with 29.8% of grants classified under F25D (REFRIGERATORS; Cold ROOMS; ICE-BOXES; Cooling OR Freezing Apparatus NOT Otherwise Provided FOR). Peak complete grant year is 2024 (13 grants) versus a trough of 1 in 2020. By volume, Sub-zero sits between SSH Communications Security OYJ and Toyo Denso Kabushiki Kaisha.

Sub-zero's three-year grant acceleration

Sub-Zero Group, Inc. shows 23 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.
