What this shows Riso's Innovation Score is 34.9/100 (49th 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 Riso?

Each dot is one of Riso’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). Riso’s own 18.8 claims/patent is ABOVE the 11.2 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Riso's grants concentrate

Riso Technologies Corporation is a focused PatentsView assignee: 1 CPC subclasses with 100% of grants classified under B41J (TYPEWRITERS; Selective Printing Mechanisms, i.e. Mechanisms Printing Otherwise Than From A FORME; Correction OF Typographical Errors). By volume, Riso sits between Riken Keiki Co., Ltd. and RK Pharma Solutions LLC.

Riso's three-year grant acceleration

Riso Technologies Corporation shows 2 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.
