What this shows Hill's Innovation Score is 63.0/100 (top 2% 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 Hill?

Each dot is one of Hill’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). Hill’s own 19.5 claims/patent is ABOVE the 12.1 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Hill's grants concentrate

Hill Phoenix, Inc. is a focused PatentsView assignee: 31 CPC subclasses with 71.7% of grants classified under F25B (Refrigeration Machines, Plants OR SYSTEMS; Combined Heating AND Refrigeration SYSTEMS; Heat Pump Systems). Peak complete grant year is 2024 (16 grants) versus a trough of 3 in 2018. By volume, Hill sits between FLSmidth A/S and Innovelis, Inc..

Hill's three-year grant acceleration

Hill Phoenix, Inc. shows 43 grants in 2022–2024 against only 18 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.
