What this shows Sixring's Innovation Score is 51.9/100 (top 11% 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 Sixring?

Each dot is one of Sixring’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). Sixring’s own 14.4 claims/patent is ABOVE the 11.6 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Sixring's grants concentrate

Sixring Inc. is a focused PatentsView assignee: 12 CPC subclasses with 100% of grants classified under D21C (Production OF Cellulose BY Removing Non-cellulose Substances From Cellulose-containing MATERIALS; Regeneration OF Pulping LIQUORS; Apparatus Therefor). Peak complete grant year is 2024 (10 grants) versus a trough of 4 in 2023. By volume, Sixring sits between Shenzhen Kanger Technology Co., Ltd and State Grid Jiangsu Electric Power Research Institute.

Sixring's three-year grant acceleration

Sixring Inc. shows 14 grants in 2022–2024 against only 0 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.
