What this shows Essex's Innovation Score is 39.6/100 (top 38% 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 10.0 claims/patent is at or below the 11.1 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Essex's grants concentrate

Essex Furukawa Magnet Wire Japan Co., Ltd. is a focused PatentsView assignee: 11 CPC subclasses with 90.9% of grants classified under H01B (CABLES; CONDUCTORS; INSULATORS; Selection OF Materials FOR Their Conductive, Insulating OR Dielectric Properties). Peak complete grant year is 2022 (5 grants) versus a trough of 1 in 2024. By volume, Essex sits between EPG (ENGINEERED Nanoproducts GERMANY) AG and Eurotech S.P.A..

Essex's three-year grant acceleration

Essex Furukawa Magnet Wire Japan Co., Ltd. shows 6 grants in 2022–2024 against only 3 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.
