What this shows Perspectum's Innovation Score is 36.7/100 (top 46% 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 Perspectum?

Each dot is one of Perspectum’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). Perspectum’s own 16.0 claims/patent is ABOVE the 8.5 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Perspectum's grants concentrate

Perspectum Limited is a focused PatentsView assignee: 4 CPC subclasses with 66.7% of grants classified under A61B (DIAGNOSIS; SURGERY; Identification). Peak complete grant year is 2022 (2 grants) versus a trough of 1 in 2020. By volume, Perspectum sits between Perkins Technical Services, Inc. and Pezy Computing K.K..

Perspectum's three-year grant acceleration

Perspectum Limited shows 4 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.
