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 2.6 claims/patent is at or below the 14.1 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 Laboratories, LLC is a focused PatentsView assignee: 4 CPC subclasses with 21.4% of grants classified under A01C (PLANTING; SOWING; Fertilising). Peak complete grant year is 2017 (6 grants) versus a trough of 1 in 2019. By volume, Essex sits between Erbe-usa, Inc. and Evolution Well Services, LLC.

Essex's three-year grant acceleration

Essex Laboratories, LLC shows 1 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.
