What this shows GRU's Innovation Score is 36.5/100 (top 46% 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 GRU?

Each dot is one of GRU’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). GRU’s own 19.6 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 GRU's grants concentrate

GRU Energy Lab Inc. is a focused PatentsView assignee: 6 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 2021 (3 grants) versus a trough of 1 in 2024. By volume, GRU sits between Grenergy Opto Inc. and GTP Schäfer Gießtechnische Produkte GmbH.

GRU's three-year grant acceleration

GRU Energy Lab Inc. shows 4 grants in 2022–2024 against only 3 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.
