What this shows Heat's Innovation Score is 24.2/100 (14th 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 Heat?

Each dot is one of Heat’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). Heat’s own 16.2 claims/patent is ABOVE the 13.8 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Heat's grants concentrate

Heat Source Energy Corp. is a focused PatentsView assignee: 2 CPC subclasses with 60% of grants classified under Y02E (Reduction OF Greenhouse GAS [GHG] Emissions, Related TO Energy Generation, Transmission OR Distribution). Peak complete grant year is 2019 (2 grants) versus a trough of 1 in 2017. By volume, Heat sits between Healionics Corporation and Heeling Sports Limited.

Heat's three-year grant acceleration

Heat Source Energy Corp. shows 1 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.
