What this shows Zerokey's Innovation Score is 33.8/100 (45th 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 Zerokey?

Each dot is one of Zerokey’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). Zerokey’s own 20.2 claims/patent is ABOVE the 14.0 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Zerokey's grants concentrate

Zerokey Inc. is a focused PatentsView assignee: 9 CPC subclasses with 92.9% of grants classified under H04W (Wireless Communication Networks). Peak complete grant year is 2018 (3 grants) versus a trough of 1 in 2017. By volume, Zerokey sits between YSI, Inc. and Zwipe AS.

Zerokey's three-year grant acceleration

Zerokey Inc. shows 2 grants in 2022–2024 against only 8 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.
