What this shows Sulfur's Innovation Score is 30.9/100 (36th 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 Sulfur's grants concentrate

Sulfur Chemical Laboratory Inc. is a focused PatentsView assignee: 10 CPC subclasses with 83.3% of grants classified under Y10T (Technical Subjects Covered BY Former US Classification). Peak complete grant year is 2017 (3 grants) versus a trough of 1 in 2016. By volume, Sulfur sits between STX Offshore & Shipbuilding Co., Ltd. and Summit Semiconductor, LLC.

Sulfur's three-year grant acceleration

Sulfur Chemical Laboratory Inc. shows 1 grants in 2022–2024 against only 1 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.
