Where Epygon's grants concentrate

Epygon is a focused PatentsView assignee: 4 CPC subclasses with 77.8% of grants classified under A61F (Filters Implantable Into Blood VESSELS; PROSTHESES; Devices Providing Patency TO, OR Preventing Collapsing OF, Tubular Structures OF THE Body, e.g. STENTS; Orthopaedic, Nursing OR Contraceptive Device). Peak complete grant year is 2020 (5 grants) versus a trough of 1 in 2019. By volume, Epygon sits between Enshu Limited and ES Cell International PTE Ltd.

Epygon's three-year grant acceleration

Epygon shows 3 grants in 2022–2024 against only 6 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.
