What this shows ET's Innovation Score is 33.4/100 (44th percentile 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 ET?

Each dot is one of ET’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). ET’s own 26.5 claims/patent is ABOVE the 15.3 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where ET's grants concentrate

ET Water Systems, Inc. is a focused PatentsView assignee: 2 CPC subclasses with 100% of grants classified under A01G (HORTICULTURE; Cultivation OF Vegetables, Flowers, Rice, Fruit, Vines, Hops OR SEAWEED; FORESTRY; Watering). Peak complete grant year is 2018 (2 grants) versus a trough of 1 in 2015. By volume, ET sits between Ericsson Modems SA and Etex Building Performance International SAS.

ET's three-year grant acceleration

ET Water Systems, Inc. shows 1 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.
