What this shows Candu's Innovation Score is 51.0/100 (top 12% 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 Candu?

Each dot is one of Candu’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). Candu’s own 16.4 claims/patent is ABOVE the 15.4 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Candu's grants concentrate

Candu Energy Inc. is a focused PatentsView assignee: 18 CPC subclasses with 80% of grants classified under Y02E (Reduction OF Greenhouse GAS [GHG] Emissions, Related TO Energy Generation, Transmission OR Distribution). Peak complete grant year is 2024 (3 grants) versus a trough of 1 in 2017. By volume, Candu sits between Camcon OIL Limited and Carbovate Development Corp..

Candu's three-year grant acceleration

Candu Energy Inc. shows 4 grants in 2022–2024 against only 0 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.
