What this shows Essence's Innovation Score is 52.5/100 (top 10% 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 Essence?

Each dot is one of Essence’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). Essence’s own 17.7 claims/patent is ABOVE the 16.0 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Essence's grants concentrate

Essence Security International (E.S.I.) Ltd. is a focused PatentsView assignee: 11 CPC subclasses with 77.8% of grants classified under G08B (Signalling OR Calling SYSTEMS; Order TELEGRAPHS; Alarm Systems). Peak complete grant year is 2023 (4 grants) versus a trough of 1 in 2019. By volume, Essence sits between Elster Solutions, LLC and Excellims Corp..

Essence's three-year grant acceleration

Essence Security International (E.S.I.) Ltd. shows 11 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.
