What this shows HF's Innovation Score is 32.7/100 (42nd percentile 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 HF's grants concentrate

HF Scientific, LLC is a focused PatentsView assignee: 9 CPC subclasses with 50% of grants classified under G01N (Investigating OR Analysing Materials BY Determining Their Chemical OR Physical Properties). Peak complete grant year is 2021 (2 grants) versus a trough of 1 in 2019. By volume, HF sits between Hemocue AB and Hill & Smith Limited.

HF's three-year grant acceleration

HF Scientific, LLC shows 4 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.
