What this shows SIT's Innovation Score is 41.4/100 (top 33% 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 SIT's grants concentrate

SIT S.P.A. is a focused PatentsView assignee: 14 CPC subclasses with 84.6% of grants classified under F23N (Regulating OR Controlling Combustion). Peak complete grant year is 2017 (2 grants) versus a trough of 1 in 2021. By volume, SIT sits between Sika Dr. Siebert & Kühn GmbH & Co. KG and Skydex Technologies, Inc..

SIT's three-year grant acceleration

SIT S.P.A. shows 5 grants in 2022–2024 against only 3 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.
