What this shows Hydropool's Innovation Score is 29.7/100 (32nd 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 Hydropool?

Each dot is one of Hydropool’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). Hydropool’s own 8.1 claims/patent is at or below the 14.9 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Hydropool's grants concentrate

Hydropool Inc. is a focused PatentsView assignee: 5 CPC subclasses with 36.4% of grants classified under E04H (Buildings OR Like Structures FOR Particular PURPOSES; Swimming OR Splash Baths OR POOLS; MASTS; FENCING; Tents OR Canopies, IN General). Peak complete grant year is 2021 (3 grants) versus a trough of 1 in 2020. By volume, Hydropool sits between Huizhou Roypow Technology Co., Ltd and Hyperstone GMBH.

Hydropool's three-year grant acceleration

Hydropool Inc. shows 5 grants in 2022–2024 against only 4 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.
