What this shows Prior's Innovation Score is 37.6/100 (top 43% 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 Prior?

Each dot is one of Prior’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). Prior’s own 5.9 claims/patent is at or below the 11.2 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Prior's grants concentrate

Prior Company Limited is a focused PatentsView assignee: 13 CPC subclasses with 33.3% of grants classified under C08G (Macromolecular Compounds Obtained Otherwise Than BY Reactions Only Involving Unsaturated Carbon-to-carbon Bonds). Peak complete grant year is 2016 (4 grants) versus a trough of 1 in 2022. By volume, Prior sits between Pressure Systems International, LLC and ProLight Opto Technology Corporation.

Prior's three-year grant acceleration

Prior Company Limited 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.
