What this shows Nemaska's Innovation Score is 41.6/100 (top 33% 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 Nemaska?

Each dot is one of Nemaska’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). Nemaska’s own 19.0 claims/patent is ABOVE the 15.5 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Nemaska's grants concentrate

Nemaska Lithium Inc. is a focused PatentsView assignee: 12 CPC subclasses with 88% of grants classified under C01D (Compounds OF Alkali Metals, i.e. Lithium, Sodium, Potassium, Rubidium, Caesium, OR Francium). Peak complete grant year is 2018 (4 grants) versus a trough of 1 in 2016. By volume, Nemaska sits between Montefiore Medical Center and NP Medical Inc..

Nemaska's three-year grant acceleration

Nemaska Lithium Inc. shows 8 grants in 2022–2024 against only 8 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.
