What this shows Pearson's Innovation Score is 28.8/100 (28th 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 Pearson?

Each dot is one of Pearson’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). Pearson’s own 12.4 claims/patent is at or below the 14.3 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Pearson's grants concentrate

Pearson Engineering Limited is a focused PatentsView assignee: 4 CPC subclasses with 62.5% of grants classified under F41H (ARMOUR; Armoured TURRETS; Armoured OR Armed VEHICLES; Means OF Attack OR Defence, e.g. Camouflage, IN General). Peak complete grant year is 2016 (2 grants) versus a trough of 1 in 2018. By volume, Pearson sits between Parexel International, LLC and Percko.

Pearson's three-year grant acceleration

Pearson Engineering Limited shows 1 grants in 2022–2024 against only 1 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.
