What this shows Essex's Innovation Score is 33.7/100 (45th 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 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 13.6 claims/patent is at or below the 14.0 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 Industries, Inc. is a focused PatentsView assignee: 9 CPC subclasses with 30% of grants classified under F16K (VALVES; TAPS; COCKS; ACTUATING-FLOATS; Devices FOR Venting OR Aerating). Peak complete grant year is 2020 (3 grants) versus a trough of 1 in 2022. By volume, Essex sits between Ernst & Young U.S. LLP and Evolve Technologies, LLC.

Essex's three-year grant acceleration

Essex Industries, Inc. 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.
