What this shows Stemcell's Innovation Score is 39.7/100 (top 37% 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 17.3 claims/patent is ABOVE the 12.6 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 Inc. is a focused PatentsView assignee: 20 CPC subclasses with 44.4% of grants classified under G01N (Investigating OR Analysing Materials BY Determining Their Chemical OR Physical Properties). Peak complete grant year is 2016 (4 grants) versus a trough of 1 in 2015. By volume, Stemcell sits between Springs Window Fashions, LLC and Sun Pleasure Company Limited.

Stemcell's three-year grant acceleration

StemCell Technologies Inc. shows 2 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.
