What this shows First's Innovation Score is 43.4/100 (top 28% 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 First?

Each dot is one of First’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). First’s own 25.8 claims/patent is ABOVE the 6.9 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where First's grants concentrate

First RF Corporation is a focused PatentsView assignee: 5 CPC subclasses with 85% of grants classified under H01Q (Antennas, i.e. Radio Aerials). Peak complete grant year is 2016 (3 grants) versus a trough of 1 in 2018. By volume, First sits between F.M. Products Inc and Foursquare Labs, Inc..

First's three-year grant acceleration

First RF Corporation shows 6 grants in 2022–2024 against only 4 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.
