Does more volume mean deeper claims for Canonical?

Each dot is one of Canonical’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). Canonical’s own 9.1 claims/patent is at or below the 16.6 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Canonical's grants concentrate

Canonical Limited is a focused PatentsView assignee: 3 CPC subclasses with 55.6% of grants classified under G06F (Electric Digital Data Processing). Peak complete grant year is 2018 (3 grants) versus a trough of 1 in 2017. By volume, Canonical sits between Caelus Technologies Limited and Cardurion Pharmaceuticals, Inc..

Canonical's three-year grant acceleration

Canonical Limited shows 3 grants in 2022–2024 against only 2 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.
