What this shows Hydrite's Innovation Score is 36.7/100 (top 46% 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 Hydrite?

Each dot is one of Hydrite’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). Hydrite’s own 18.7 claims/patent is ABOVE the 12.4 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Hydrite's grants concentrate

Hydrite Chemical Co. is a focused PatentsView assignee: 18 CPC subclasses with 40% of grants classified under B01D (Separation). Peak complete grant year is 2018 (3 grants) versus a trough of 1 in 2015. By volume, Hydrite sits between Huvis Corporation and Haechitech Corporation.

Hydrite's three-year grant acceleration

Hydrite Chemical Co. shows 1 grants in 2022–2024 against only 3 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.
