What this shows 0chain's Innovation Score is 42.7/100 (top 30% 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 0chain?

Each dot is one of 0chain’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). 0chain’s own 22.2 claims/patent is ABOVE the 15.5 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where 0chain's grants concentrate

0chain Corp. is a focused PatentsView assignee: 10 CPC subclasses with 91.7% of grants classified under H04L (Transmission OF Digital Information, e.g. Telegraphic Communication). Peak complete grant year is 2021 (5 grants) versus a trough of 1 in 2022. By volume, 0chain sits between artience Co., Ltd. and 365 Retail Markets, LLC.

0chain's three-year grant acceleration

0chain Corp. shows 7 grants in 2022–2024 against only 5 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.
