What this shows Essex's Innovation Score is 51.4/100 (top 11% 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 Essex?

Each dot is one of Essex’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). Essex’s own 19.0 claims/patent is ABOVE the 16.4 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Essex's grants concentrate

Essex Furukawa Magnet Wire USA LLC is a focused PatentsView assignee: 10 CPC subclasses with 91.7% of grants classified under H01B (CABLES; CONDUCTORS; INSULATORS; Selection OF Materials FOR Their Conductive, Insulating OR Dielectric Properties). Peak complete grant year is 2023 (6 grants) versus a trough of 1 in 2020. By volume, Essex sits between Esko Software BV and Evertree.

Essex's three-year grant acceleration

Essex Furukawa Magnet Wire USA LLC shows 10 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.
