What this shows FK's Innovation Score is 36.7/100 (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 FK?

Each dot is one of FK’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). FK’s own 8.6 claims/patent is at or below the 11.4 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where FK's grants concentrate

FK Irons Inc. is a focused PatentsView assignee: 5 CPC subclasses with 50% of grants classified under A61M (Devices FOR Introducing Media Into, OR Onto, THE Body ; Devices FOR Transducing Body Media OR FOR Taking Media From THE Body ; Devices FOR Producing OR Ending Sleep OR Stupor). Peak complete grant year is 2024 (9 grants) versus a trough of 1 in 2019. By volume, FK sits between Equity Shift, Inc. and Free-free Industrial Corp..

FK's three-year grant acceleration

FK Irons Inc. shows 17 grants in 2022–2024 against only 10 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.
