What this shows Keyline's Innovation Score is 34.0/100 (46th 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 Keyline?

Each dot is one of Keyline’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). Keyline’s own 8.6 claims/patent is at or below the 11.0 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Keyline's grants concentrate

Keyline S.p.A. is a focused PatentsView assignee: 7 CPC subclasses with 20% of grants classified under B23C (Milling). By volume, Keyline sits between Ketch Kloud, Inc. and Kiinja Corporation.

Keyline's three-year grant acceleration

Keyline S.p.A. shows 2 grants in 2022–2024 against only 0 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.
