What this shows EPC's Innovation Score is 36.4/100 (top 46% 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 EPC?

Each dot is one of EPC’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). EPC’s own 1.6 claims/patent is at or below the 15.7 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where EPC's grants concentrate

EPC Product LLC is a focused PatentsView assignee: 3 CPC subclasses with 7.1% of grants classified under H05B (Electric HEATING; Electric Light Sources NOT Otherwise Provided FOR; Circuit Arrangements FOR Electric Light Sources, IN General). Peak complete grant year is 2022 (7 grants) versus a trough of 1 in 2020. By volume, EPC sits between Entersekt International Limited and Essen Tech Co., Ltd..

EPC's three-year grant acceleration

EPC Product LLC shows 13 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.
