What this shows Purissima's Innovation Score is 39.1/100 (top 39% 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 Purissima?

Each dot is one of Purissima’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). Purissima’s own 20.0 claims/patent is ABOVE the 18.3 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Purissima's grants concentrate

Purissima, Inc. is a focused PatentsView assignee: 4 CPC subclasses with 100% of grants classified under C12P (Fermentation OR Enzyme-using Processes TO Synthesise A Desired Chemical Compound OR Composition OR TO Separate Optical Isomers From A Racemic Mixture). Peak complete grant year is 2022 (4 grants) versus a trough of 1 in 2020. By volume, Purissima sits between Proximie Inc. and Q-yield Outdoor Gear Ltd..

Purissima's three-year grant acceleration

Purissima, Inc. shows 4 grants in 2022–2024 against only 2 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.
