What this shows PF's Innovation Score is 39.3/100 (top 38% 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 PF?

Each dot is one of PF’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). PF’s own 23.8 claims/patent is ABOVE the 13.9 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where PF's grants concentrate

PF Waterworks LP is a focused PatentsView assignee: 7 CPC subclasses with 95% of grants classified under E03C (Domestic Plumbing Installations FOR Fresh Water OR Waste Water ; Sinks). Peak complete grant year is 2019 (4 grants) versus a trough of 1 in 2017. By volume, PF sits between PAN Pacific Plastics MFG., Inc. and Pocared Diagnostics Ltd..

PF's three-year grant acceleration

PF Waterworks LP shows 7 grants in 2022–2024 against only 9 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.
