Does more volume mean deeper claims for Canadian?

Each dot is one of Canadian’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). Canadian’s own 5.8 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 Canadian's grants concentrate

Canadian Solar Manufacturing (CHANGSHU) Inc. is a focused PatentsView assignee: 4 CPC subclasses with 33.3% of grants classified under Y02E (Reduction OF Greenhouse GAS [GHG] Emissions, Related TO Energy Generation, Transmission OR Distribution). Peak complete grant year is 2020 (3 grants) versus a trough of 1 in 2021. By volume, Canadian sits between C3 Corporation and Capital Normal University.

Canadian's three-year grant acceleration

Canadian Solar Manufacturing (CHANGSHU) Inc. shows 4 grants in 2022–2024 against only 4 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.
