What this shows Sunfire's Innovation Score is 33.2/100 (44th 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 Sunfire?

Each dot is one of Sunfire’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). Sunfire’s own 10.6 claims/patent is at or below the 13.3 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Sunfire's grants concentrate

Sunfire GmbH is a focused PatentsView assignee: 12 CPC subclasses with 100% of grants classified under Y02E (Reduction OF Greenhouse GAS [GHG] Emissions, Related TO Energy Generation, Transmission OR Distribution). Peak complete grant year is 2015 (2 grants) versus a trough of 1 in 2019. By volume, Sunfire sits between Sun Hill Industries, Inc. and Supercooler Technologies, Inc..

Sunfire's three-year grant acceleration

Sunfire GmbH 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.
