Does more volume mean deeper claims for Gemvax?
Each dot is one of Gemvax’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). Gemvax’s own 12.0 claims/patent is at or below the 15.2 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.
Where Gemvax's grants concentrate
GemVax & Kael Co., Ltd. is a focused PatentsView assignee: 11 CPC subclasses with 97.6% of grants classified under A61K (Preparations FOR Medical, Dental OR Toiletry Purposes). Peak complete grant year is 2021 (8 grants) versus a trough of 1 in 2016. By volume, Gemvax sits between General Plastic Industrial Co., Ltd. and Hospices Civils DE Lyon.
Gemvax's three-year grant acceleration
GemVax & Kael Co., Ltd. shows 10 grants in 2022–2024 against only 17 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.
