What this shows Sunarrow's Innovation Score is 28.4/100 (27th 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 Sunarrow?

Each dot is one of Sunarrow’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). Sunarrow’s own 10.6 claims/patent is at or below the 11.7 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Sunarrow's grants concentrate

Sunarrow Ltd is a focused PatentsView assignee: 12 CPC subclasses with 71.4% of grants classified under B32B (Layered Products, i.e. Products Built-up OF Strata OF Flat OR Non-flat, e.g. Cellular OR Honeycomb, Form). Peak complete grant year is 2020 (3 grants) versus a trough of 2 in 2021. By volume, Sunarrow sits between Styrolution Europe GMBH and Suntree Technologies Holdings, LLC.

Sunarrow's three-year grant acceleration

Sunarrow Ltd shows 2 grants in 2022–2024 against only 5 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.
