What this shows Epic's Innovation Score is 49.5/100 (top 15% 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 Epic?

Each dot is one of Epic’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). Epic’s own 23.8 claims/patent is ABOVE the 18.3 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Epic's grants concentrate

Epic Lift Systems is a focused PatentsView assignee: 4 CPC subclasses with 94.7% of grants classified under E21B (Earth OR Rock DRILLING; Obtaining OIL, GAS, Water, Soluble OR Meltable Materials OR A Slurry OF Minerals From Wells). Peak complete grant year is 2024 (4 grants) versus a trough of 1 in 2016. By volume, Epic sits between Emerson Vulcan Holding LLC and Eternal East (HK) Ltd..

Epic's three-year grant acceleration

Epic Lift Systems shows 8 grants in 2022–2024 against only 3 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.
