What this shows Zoeller's Innovation Score is 51.3/100 (top 12% 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 Zoeller?

Each dot is one of Zoeller’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). Zoeller’s own 14.9 claims/patent is at or below the 16.7 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Zoeller's grants concentrate

Zoeller Pump Company, LLC is a focused PatentsView assignee: 14 CPC subclasses with 53.8% of grants classified under E03F (SEWERS; Cesspools). Peak complete grant year is 2022 (3 grants) versus a trough of 1 in 2021. By volume, Zoeller sits between Zhejiang Kaiying New Materials Co., Ltd. and iBio, Inc..

Zoeller's three-year grant acceleration

Zoeller Pump Company, LLC shows 7 grants in 2022–2024 against only 1 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.
