Does more volume mean deeper claims for Waterfurnace?

Each dot is one of Waterfurnace’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). Waterfurnace’s own 18.9 claims/patent is ABOVE the 16.5 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Waterfurnace's grants concentrate

WaterFurnace International, Inc. is a focused PatentsView assignee: 6 CPC subclasses with 81.3% of grants classified under F25B (Refrigeration Machines, Plants OR SYSTEMS; Combined Heating AND Refrigeration SYSTEMS; Heat Pump Systems). Peak complete grant year is 2023 (4 grants) versus a trough of 1 in 2021. By volume, Waterfurnace sits between Wombat Security Technologies, Inc. and WingArc1st Inc..

Waterfurnace's three-year grant acceleration

WaterFurnace International, Inc. shows 8 grants in 2022–2024 against only 3 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.
