What this shows BIG's Innovation Score is 32.8/100 (42nd 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 BIG?

Each dot is one of BIG’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). BIG’s own 16.0 claims/patent is ABOVE the 14.4 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where BIG's grants concentrate

BIG SUN Energy Technology Inc. is a focused PatentsView assignee: 12 CPC subclasses with 87.5% of grants classified under Y02E (Reduction OF Greenhouse GAS [GHG] Emissions, Related TO Energy Generation, Transmission OR Distribution). Peak complete grant year is 2016 (3 grants) versus a trough of 1 in 2019. By volume, BIG sits between Beyond AIR, Inc. and Biofridge Inc..

BIG's three-year grant acceleration

BIG SUN Energy Technology Inc. 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.
