What this shows Fetu's Innovation Score is 32.1/100 (40th 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 Fetu?

Each dot is one of Fetu’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). Fetu’s own 25.8 claims/patent is ABOVE the 14.6 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Fetu's grants concentrate

Fetu Limited is a focused PatentsView assignee: 6 CPC subclasses with 100% of grants classified under F01C (Rotary-piston OR Oscillating-piston Machines OR Engines). Peak complete grant year is 2021 (2 grants) versus a trough of 1 in 2019. By volume, Fetu sits between FD IP & Licensing LLC and Fidelity National Information Services, Inc..

Fetu's three-year grant acceleration

Fetu Limited 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.
