What this shows Pentair's Innovation Score is 48.3/100 (top 17% 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 Pentair?

Each dot is one of Pentair’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). Pentair’s own 13.5 claims/patent is at or below the 15.7 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Pentair's grants concentrate

Pentair Residential Filtration, LLC is a focused PatentsView assignee: 17 CPC subclasses with 52.9% of grants classified under C02F (Treatment OF Water, Waste Water, Sewage, OR Sludge). Peak complete grant year is 2017 (9 grants) versus a trough of 1 in 2018. By volume, Pentair sits between Prinoth S.P.A. and QM Power, Inc..

Pentair's three-year grant acceleration

Pentair Residential Filtration, LLC 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.
