What this shows 21's Innovation Score is 28.6/100 (28th 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 21?

Each dot is one of 21’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). 21’s own 15.0 claims/patent is ABOVE the 12.0 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where 21's grants concentrate

21, Inc. is a focused PatentsView assignee: 6 CPC subclasses with 75% of grants classified under H04L (Transmission OF Digital Information, e.g. Telegraphic Communication). Peak complete grant year is 2019 (2 grants) versus a trough of 1 in 2017. By volume, 21 sits between 1080 Network, Inc. and 3nine AB.

21's three-year grant acceleration

21, Inc. shows 2 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.
