What this shows Essex's Innovation Score is 42.4/100 (top 31% 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 10.9 claims/patent is ABOVE the 8.9 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 Electronics is a focused PatentsView assignee: 6 CPC subclasses with 42.9% of grants classified under G07C (Time OR Attendance REGISTERS; Registering OR Indicating THE Working OF MACHINES; Generating Random NUMBERS; Voting OR Lottery APPARATUS; Arrangements, Systems OR Apparatus FOR Checking NOT Provided FO). Peak complete grant year is 2015 (3 grants) versus a trough of 1 in 2018. By volume, Essex sits between Ergon International GmbH and Evergreen Enterprises of Virginia, LLC.

Essex's three-year grant acceleration

Essex Electronics shows 3 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.
