What this shows REN's Innovation Score is 31.9/100 (39th 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.
REN Fuel K2B AB is a focused PatentsView assignee: 11 CPC subclasses with 100% of grants classified under C07G (Compounds OF Unknown Constitution). Peak complete grant year is 2018 (2 grants) versus a trough of 1 in 2019. By volume, REN sits between Regina Catene Calibrate S.P.A. and Repnow Inc..
REN Fuel K2B AB shows 1 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.
