Does more volume mean deeper claims for Shizuoka?

Each dot is one of Shizuoka’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). Shizuoka’s own 11.0 claims/patent is ABOVE the 10.8 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Shizuoka's grants concentrate

Shizuoka Prefectural University Corporation is a focused PatentsView assignee: 9 CPC subclasses with 83.3% of grants classified under A61K (Preparations FOR Medical, Dental OR Toiletry Purposes). By volume, Shizuoka sits between Shinko Metal Products Co., Ltd. and Shummi Enterprise Co., Ltd..

Shizuoka's three-year grant acceleration

Shizuoka Prefectural University Corporation shows 1 grants in 2022–2024 against only 2 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.
