What this shows Selas's Innovation Score is 30.3/100 (34th 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 Selas?

Each dot is one of Selas’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). Selas’s own 14.5 claims/patent is ABOVE the 13.2 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Selas's grants concentrate

Selas Heat Technology Company LLC is a focused PatentsView assignee: 8 CPC subclasses with 70% of grants classified under F23D (Burners). Peak complete grant year is 2019 (3 grants) versus a trough of 1 in 2015. By volume, Selas sits between Schurter AG and Sensewhere Limited.

Selas's three-year grant acceleration

Selas Heat Technology Company LLC shows 2 grants in 2022–2024 against only 4 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.
