What this shows Whirlpool's Innovation Score is 47.5/100 (top 18% 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.

Where Whirlpool's grants concentrate

Whirlpool S.A. is a focused PatentsView assignee: 47 CPC subclasses with 54.9% of grants classified under F04B (Positive-displacement Machines FOR LIQUIDS; Pumps). Peak complete grant year is 2015 (21 grants) versus a trough of 1 in 2024. By volume, Whirlpool sits between Transdermal Biotechnology, Inc. and Bwxt mPower, Inc..

Whirlpool's three-year grant acceleration

Whirlpool S.A. shows 3 grants in 2022–2024 against only 14 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.
