What this shows S.j.'s Innovation Score is 27.6/100 (24th 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 S.j.?
Each dot is one of S.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). S.j.’s own 8.1 claims/patent is at or below the 9.3 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.
Where S.j.'s grants concentrate
S.J. Electro Systems, LLC is a focused PatentsView assignee: 10 CPC subclasses with 15% of grants classified under H01H (Electric SWITCHES; RELAYS; SELECTORS; Emergency Protective Devices). Peak complete grant year is 2017 (5 grants) versus a trough of 1 in 2016. By volume, S.j. sits between Russell Brands, LLC and Sanvean Technologies LLC.
S.j.'s three-year grant acceleration
S.J. Electro Systems, LLC shows 1 grants in 2022–2024 against only 6 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.
