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.

Does more volume mean deeper claims for REN?

Each dot is one of REN’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). REN’s own 18.7 claims/patent is ABOVE the 14.7 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where REN's grants concentrate

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's three-year grant acceleration

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.
