What this shows E.j.'s Innovation Score is 33.8/100 (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 E.j.?

Each dot is one of E.j.’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). E.j.’s own 14.0 claims/patent is at or below the 14.7 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where E.j.'s grants concentrate

E.J. Brooks Company is a focused PatentsView assignee: 9 CPC subclasses with 50% of grants classified under G09F (DISPLAYING; ADVERTISING; SIGNS; Labels OR NAME-PLATES; Seals). Peak complete grant year is 2016 (4 grants) versus a trough of 1 in 2018. By volume, E.j. sits between Dräger Medical GmbH and Emeh, Inc..

E.j.'s three-year grant acceleration

E.J. Brooks Company shows 3 grants in 2022–2024 against only 4 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.
