What this shows Starfire's Innovation Score is 48.8/100 (top 16% 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 Starfire?

Each dot is one of Starfire’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). Starfire’s own 19.3 claims/patent is ABOVE the 10.7 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Starfire's grants concentrate

Starfire Energy is a focused PatentsView assignee: 8 CPC subclasses with 100% of grants classified under C01C (AMMONIA; CYANOGEN; Compounds Thereof). Peak complete grant year is 2023 (3 grants) versus a trough of 1 in 2020. By volume, Starfire sits between SRG Global Liria, S.L. and Stefano Ricci S.P.A..

Starfire's three-year grant acceleration

Starfire Energy shows 6 grants in 2022–2024 against only 1 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.
