What this shows Stemcell's Innovation Score is 51.7/100 (top 11% 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 Stemcell?

Each dot is one of Stemcell’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). Stemcell’s own 18.1 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 Stemcell's grants concentrate

Stemcell Technologies Canada Inc. is a focused PatentsView assignee: 11 CPC subclasses with 61.5% 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 2024 (3 grants) versus a trough of 2 in 2023. By volume, Stemcell sits between Staples THE Office Superstore, LLC and SUN Drilling Products Corporation.

Stemcell's three-year grant acceleration

Stemcell Technologies Canada Inc. shows 5 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.
