What this shows Empire's Innovation Score is 32.0/100 (40th 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 Empire?

Each dot is one of Empire’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). Empire’s own 17.3 claims/patent is ABOVE the 16.3 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Empire's grants concentrate

Empire Technological Group Limited is a focused PatentsView assignee: 3 CPC subclasses with 75% of grants classified under G07F (Coin-freed OR Like Apparatus). Peak complete grant year is 2020 (3 grants) versus a trough of 1 in 2022. By volume, Empire sits between Ellansalabs Inc. and Engineer.ai Corp..

Empire's three-year grant acceleration

Empire Technological Group Limited shows 5 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.
