What this shows Thermal's Innovation Score is 35.1/100 (top 50% 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 Thermal?

Each dot is one of Thermal’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). Thermal’s own 23.6 claims/patent is ABOVE the 16.0 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Thermal's grants concentrate

Thermal Storage Systems is a focused PatentsView assignee: 4 CPC subclasses with 100% of grants classified under F24S (Solar Heat COLLECTORS; Solar Heat Systems). Peak complete grant year is 2017 (2 grants) versus a trough of 1 in 2019. By volume, Thermal sits between The Willamette Valley Company LLC and Thinx Inc..

Thermal's three-year grant acceleration

Thermal Storage Systems shows 2 grants in 2022–2024 against only 2 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.
