Does more volume mean deeper claims for Chubu?

Each dot is one of Chubu’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). Chubu’s own 10.4 claims/patent is ABOVE the 7.7 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Chubu's grants concentrate

Chubu University Educational Foundation is a focused PatentsView assignee: 32 CPC subclasses with 30.8% of grants classified under C07K (Peptides). Peak complete grant year is 2022 (4 grants) versus a trough of 1 in 2015. By volume, Chubu sits between CHI MEI Medical Center and Cirocomm Technology Corp..

Chubu's three-year grant acceleration

Chubu University Educational Foundation shows 6 grants in 2022–2024 against only 1 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.
