What this shows Hrst's Innovation Score is 37.0/100 (top 45% 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 Hrst?

Each dot is one of Hrst’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). Hrst’s own 15.9 claims/patent is ABOVE the 12.6 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Hrst's grants concentrate

Hrst, Inc. is a focused PatentsView assignee: 14 CPC subclasses with 50% of grants classified under F22B (Methods OF Steam GENERATION; Steam Boilers). Peak complete grant year is 2024 (2 grants) versus a trough of 1 in 2015. By volume, Hrst sits between Horiba France SAS and Htl-strefa Spolka Akcyjna.

Hrst's three-year grant acceleration

Hrst, Inc. shows 3 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.
