Does more volume mean deeper claims for Zurn?

Each dot is one of Zurn’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). Zurn’s own 13.6 claims/patent is ABOVE the 11.1 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Zurn's grants concentrate

Zurn Water, LLC is a focused PatentsView assignee: 32 CPC subclasses with 27.8% of grants classified under E03C (Domestic Plumbing Installations FOR Fresh Water OR Waste Water ; Sinks). By volume, Zurn sits between Zena Technologies, Inc. and Zinniatek Limited.

Zurn's three-year grant acceleration

Zurn Water, LLC shows 6 grants in 2022–2024 against only 0 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.
