What this shows Biosurfit's Innovation Score is 37.7/100 (top 43% 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 Biosurfit?

Each dot is one of Biosurfit’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). Biosurfit’s own 14.5 claims/patent is at or below the 15.3 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Biosurfit's grants concentrate

Biosurfit, S.A. is a focused PatentsView assignee: 19 CPC subclasses with 71.9% of grants classified under G01N (Investigating OR Analysing Materials BY Determining Their Chemical OR Physical Properties). Peak complete grant year is 2018 (8 grants) versus a trough of 1 in 2015. By volume, Biosurfit sits between Austin Hardware & Supply, Inc. and Brand GMBH & Co KG.

Biosurfit's three-year grant acceleration

Biosurfit, S.A. shows 3 grants in 2022–2024 against only 13 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.
