What this shows Hydroacoustics's Innovation Score is 45.5/100 (top 23% 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 Hydroacoustics?

Each dot is one of Hydroacoustics’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). Hydroacoustics’s own 15.7 claims/patent is ABOVE the 9.2 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Hydroacoustics's grants concentrate

Hydroacoustics Inc. is a focused PatentsView assignee: 7 CPC subclasses with 83.3% of grants classified under E21B (Earth OR Rock DRILLING; Obtaining OIL, GAS, Water, Soluble OR Meltable Materials OR A Slurry OF Minerals From Wells). Peak complete grant year is 2024 (2 grants) versus a trough of 1 in 2020. By volume, Hydroacoustics sits between Hussey Seating Company and HyperAccel Co., Ltd..

Hydroacoustics's three-year grant acceleration

Hydroacoustics Inc. shows 4 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.
