What this shows Atomic's Innovation Score is 44.0/100 (top 27% 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 Atomic?

Each dot is one of Atomic’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). Atomic’s own 19.6 claims/patent is ABOVE the 12.9 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Atomic's grants concentrate

Atomic Energy OF Canada Limited is a focused PatentsView assignee: 26 CPC subclasses with 71.8% of grants classified under Y02E (Reduction OF Greenhouse GAS [GHG] Emissions, Related TO Energy Generation, Transmission OR Distribution). Peak complete grant year is 2017 (11 grants) versus a trough of 2 in 2020. By volume, Atomic sits between AIC Inc. and Aldeyra Therapeutics, Inc..

Atomic's three-year grant acceleration

Atomic Energy OF Canada Limited shows 3 grants in 2022–2024 against only 14 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.
