What this shows Waterway's Innovation Score is 29.0/100 (29th 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 Waterway?

Each dot is one of Waterway’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). Waterway’s own 7.5 claims/patent is at or below the 16.1 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Waterway's grants concentrate

Waterway Plastics is a focused PatentsView assignee: 17 CPC subclasses with 54.5% of grants classified under A61H (Physical Therapy Apparatus, e.g. Devices FOR Locating OR Stimulating Reflex Points IN THE BODY; Artificial RESPIRATION; MASSAGE; Bathing Devices FOR Special Therapeutic OR Hygienic Purposes OR Specifi). Peak complete grant year is 2017 (3 grants) versus a trough of 1 in 2015. By volume, Waterway sits between Wuhan Institute OF Physics AND Mathematics, Chinese Academy OF Sciences and Wein Holding, LLC.

Waterway's three-year grant acceleration

Waterway Plastics shows 1 grants in 2022–2024 against only 5 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.
