What this shows FCI's Innovation Score is 36.2/100 (top 47% 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 FCI?

Each dot is one of FCI’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). FCI’s own 12.8 claims/patent is at or below the 16.3 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where FCI's grants concentrate

FCI Holdings Delaware, Inc. is a focused PatentsView assignee: 14 CPC subclasses with 95.5% of grants classified under E21D (SHAFTS; TUNNELS; GALLERIES; Large Underground Chambers). Peak complete grant year is 2015 (4 grants) versus a trough of 1 in 2023. By volume, FCI sits between Epirus, Inc. and Fitipower Integrated Technology Inc..

FCI's three-year grant acceleration

FCI Holdings Delaware, Inc. shows 4 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.
