What this shows J.f.'s Innovation Score is 44.1/100 (top 26% 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 J.f.?

Each dot is one of J.f.’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). J.f.’s own 17.3 claims/patent is ABOVE the 10.5 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where J.f.'s grants concentrate

J.F. Brennan Company, Inc. is a focused PatentsView assignee: 15 CPC subclasses with 66.7% of grants classified under E02B (Hydraulic Engineering). Peak complete grant year is 2016 (2 grants) versus a trough of 1 in 2017. By volume, J.f. sits between Ivanhoe HTL Petroleum Ltd. and Jafer Enterprises R&D SL.

J.f.'s three-year grant acceleration

J.F. Brennan Company, Inc. shows 2 grants in 2022–2024 against only 1 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.
