What this shows Carleton's Innovation Score is 48.5/100 (top 16% 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 Carleton?

Each dot is one of Carleton’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). Carleton’s own 17.6 claims/patent is ABOVE the 13.0 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Carleton's grants concentrate

Carleton University is a focused PatentsView assignee: 11 CPC subclasses with 40% of grants classified under C12N (Microorganisms OR ENZYMES; Compositions THEREOF; Propagating, Preserving, OR Maintaining MICROORGANISMS; Mutation OR Genetic ENGINEERING; Culture Media). Peak complete grant year is 2023 (2 grants) versus a trough of 1 in 2024. By volume, Carleton sits between Carego Innovative Solutions, Inc. and Carterra, Inc..

Carleton's three-year grant acceleration

Carleton University shows 3 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.
