What this shows EFC's Innovation Score is 32.7/100 (42nd 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 EFC?

Each dot is one of EFC’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). EFC’s own 13.0 claims/patent is ABOVE the 9.1 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where EFC's grants concentrate

EFC Systems, Inc. is a focused PatentsView assignee: 9 CPC subclasses with 75% of grants classified under B05B (Spraying APPARATUS; Atomising APPARATUS; Nozzles). Peak complete grant year is 2015 (2 grants) versus a trough of 1 in 2018. By volume, EFC sits between Ecole Nationale Superieure DE Techniques Avancees and Eken Electronics Limited.

EFC's three-year grant acceleration

EFC Systems, Inc. shows 1 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.
