What this shows Plasmology4's Innovation Score is 42.6/100 (top 30% 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.

Where Plasmology4's grants concentrate

Plasmology4 is a focused PatentsView assignee: 14 CPC subclasses with 81.3% of grants classified under A61L (Methods OR Apparatus FOR Sterilising Materials OR Objects IN GENERAL; Disinfection, Sterilisation OR Deodorisation OF AIR; Chemical Aspects OF Bandages, Dressings, Absorbent Pads OR Surgical ARTICLES;). Peak complete grant year is 2016 (10 grants) versus a trough of 1 in 2020. By volume, Plasmology4 sits between Paper Converting Machine Company and Putco, Inc..

Plasmology4's three-year grant acceleration

Plasmology4 shows 4 grants in 2022–2024 against only 5 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.
